Need some help from JP-LRP07 owners.....

[jaycoux]

Ok, I'm getting close to buying one of these. I have a few questions for those of you with first hand experience.

First, the barrel is a 1:10 twist. I committed a long time ago to run smk 175's, and all my experience in 308 is with 1:11.25 twist. Does anyone run 175 smk in their JP and is the accuracy good? Is there anything out there tbat the rifle really favors?

Second, I hear alot of people talking about how great their lrps are but the groups available on line seem to hover around 1". The rep i spoke to suggested 1" could be expected with factory match and 1/2" with reloads. What is your experience?

Thanks
J

Is there anything out there tbat the rifle really favors? You'll not have an ounce of trouble running the 175gr SMKs extremely accurately out of the JP 1:10 twist barrels of at least 18" in my experience (the 16" gives up a hair too much velocity with the 175s in my experience if you are wanting to stretch out to the longer ranges). At one time, John Paul and others at JPE were specifically recommending the 175gr loads for their 1:10 twist barreled .308/7.62 gassers, so I truly don't think you'll have anything to worry about with that twist versus the slightly slower, 1:11.25 twist you are used to.

Second, I hear alot of people talking about how great their lrps are but the groups available on line seem to hover around 1". The rep i spoke to suggested 1" could be expected with factory match and 1/2" with reloads. What is your experience? I don't think that the JP rep you spoke with is out of line with respect to those accuracy claims as JP, like almost ALL major AR mfgs, including some custom just shops, vastly UNDER-sell the accuracy capabilities of their large-frame ARs for multiple reasons. In my own personal experience, and having witnessed various JP rifles in the hands of a competent shooter with experience an understanding of how to properly drive a large-frame semi-auto...sub-MOA accuracy with factory match fodder is pretty easy to achieve and with reloads, the rifles are even more capable. Simply put...the JP offerings are some of THE MOST ACCURATE rifles on the market.

I am relatively new to precision shooting, am not a great group shooter, using a 3-9x optic and even when I call a flier I can get most groups under 1moa with 168 hornady tap. Yesterday my cold bore +2 measured .488 @100 with all rounds inside .5 of poa. Looking through my data book and filtering out shots I KNOW were me, I feel confident that my rifle can hold .8 all day....now if only I could shoot .8 all day.

JP is a little conservative on their accuracy estimates.

I was doing some load testing at 500Y with my 6.5CM LRP-07 yesterday morning. 123 Scenars, H4350, GM210M primers. Here is the best and worst group out of 7 different loads, 4 rounds per load. Grid size on the paper is exactly 1".



Last weekend I was shooting steel at 1150 and had no problem staying on a 45% IPSC torso for 7 of 10 rounds. Shifting winds got me on the 3 I missed, the hills out there are tough to read.

I also have a pair of JP SCR-11s in .223. The 18" barrel has a 1-6 scope on it and the farthest I've shot it for accuracy was at 300Y and it held about 0.5 MOA. The 22" barrel has a 5-25 on it and when the wind cooperates with the 53gr Vmax it will hold about 0.3MOA @ 300Y and 0.5 MOA @ 500. The 22" rifle is a ground squirrel slaying machine.

The weak link in the system in my case is me-- I'm not as consistent with semis as I am with a bolt rifle. Doesn't stop me from enjoying them though, they're the best AR rifles I've owned to date. I'm going to order a 2nd LRP-07 next year.

Check my pron post.

They shoot unbelievably well.

I was back and fourth between a Gap and JP and am very happy I choose teh LRP.

1st day out while still breaking in the barrel shooting from a unstable table.

 

[jevan126]

I have an LRP-07 with 18" light contour barrel and a 1:10 twist. I just went out to a friends house and he has a few acres of land with a small 100yard range he built. Well I took with me some Southwest 175gr smk and some Buffalo Bore 175gr sniper ammo and finally some ASYM 175gr smk, well I did a group of 5 shots @ 100yards with a Swarovski Z6i scope and got an average of less than one 1" with all 3 of those ammo, my scope is only a 6x so if you were to put on say 25x, I would be willing to bet that in the right hands and right conditions this rifle would stay under .50 with no problem. If you want PROOF that this RIFLE is Dead Nuts ACCURATE, google AMMOLAND and type with it JP rifles see use by AMU Team and read where Staff Sgt. Daniel Horner was getting .50 moa accuracy past 700 yards. If that isn't accuracy for a gas gun I don't know what is!

 

[nombei]

my LRP-07 with 18" barrel seems to prefer 168gr over 175gr for the groups i've shot at 100yds -- don't have a range with a longer distance close by... in fact i was doing a little battle between my JP and Sig SSG 3000 today and shot AE 168gr OTM, Prvi 168gr Match, and FGM 175gr. shot the groups using a Harris bipod and rear sandbag and the same Bushnell ET 4.5-30x50mm scope on both rifles.

some caveats here...
me: i'm probably nothing close to a precision shooter. i've never been trained to shoot. i just like going to the range. i also tend to screw up the 4th shot of my 5 shot groups, so for most of the number i list below, you can assume that these are 4 shot groups. also, i don't think i was shooting particularly well today; was definitely more consistent last weekend.

the rifles:
the Sig is a heavy barreled, bolt action with a 24" barrel (1 in 11 twist) and 2-stage trigger.
the JP is a light contour barreled, semi-auto with 18" barrel (1 in 10 twist) and single stage trigger.

and now for some results...

Sig SSG 3000
best group today was 0.375" ctr to ctr using AE 168gr OTM.
my best group yet with that rifle has been 0.25", also using AE 168gr OTM.
when i do my part, i tend to be sub 0.50" with the AE 168gr OTM.

best group i shot with FGM 175gr today was 0.875".
my best group yet with FGM 175gr has been 0.3125".
when i do my part, i tend to get groups between 0.6" and 0.75".

best group with the Prvi 168gr today was also 0.875".
my best group yet with Prvi 168gr has been 0.50".
when i do my part, i tend to get groups between 0.6" and 0.875".

i've also shot Norma 168gr through the Sig before and that also tends to fall in the 0.6" to 0.75" range.

so at least for me, and shooting at 100yd, i have seen my best and most consistent groups with AE 168gr.


JP LRP-07
best group today was 0.75". got that with both AE 168gr OTM and Prvi 168gr.
those are also the best groups i've gotten from the JP so far.
when i do my part, i tend to get groups between 0.875" and 1.25" with the AE 168gr OTM
and with the Prvi 168gr, i tend to be between 1" and 1.5"

best group today with the FGM 175gr was 1.0".
my best group yet with FGM 175gr has been 0.875".
when i do my part, i tend to get groups between 1.1" and 1.7"

so again, for me and shooting at 100yds, the AE 168gr OTM seems to be the winning round.


going forward, i want to get to the point where i can consistently get between 0.25" and 0.4" with the Sig SSG 3000 (and for all 5 shots!). i think the AE 168gr OTM is the round that will be able to get me there, just need to do my part better.

for the JP, i'm actually going to be a bit disappointed if i can't start getting some 0.5" groups each time i shoot. i'm sure that rifle has that accuracy in it, but i haven't been able to get it there yet. and as with the Sig, i think the AE 168gr OTM is the round i'll be shooting when i eventually get there.

 

[jaycoux]

See above.

Thanks ORD. My experience with large frame ar's is that most average shooters can get a good quality rifle to shoot moa with match ammo. In retrospect it seems obvious why jp uses moa as their expected accuracy.

I am going to order a 16" lrp for suppressed hunting and LR range shooting. I have already asked jp their opinion of cheek weld using a ubr vs. Prs stock with a 3.5-15 F1 Nightforce. I thought if anyone had their own personal experience with either of these stocks on their jp they might chime in. I was told by JP the ubr would be just fine. While I trust what they are saying i was looking for more opinions. Everyone is built different , so the more input the better.

Thank you Nombei, that is a very detailed and honest response. I dealt with some of your concerns when i bought my obr. I was sure something was wrong with it until I read the very good advice of members on this very board. I will occaisionally throw a shot but it is always when i get mentally lazy and forget what i am shooting. FWIW i did not get the 1/2 moa accuracy you are looking for until i started reloading.

For hunting both the prs and ubr are heavier than hell. I use just the ctr and have awesome results with both bench shootingand hunting.

 

[webvantage]

I have a 20" LRP .308 with Nightforce 3.5-15 F1 on JP rings and the PRS stock, so similar to what you want to put together. I think you will need the PRS's adjustability if using the NF NSX F1, at least i did. Its a great setup but its heavy. I have no problem hiking all day with it in my pack but i would not want to carry or sling it for a long period of time. Like what everyone else has said, JP is very conservative on their accuracy estimates but the rifle is extremely accurate. Mine prefers 168gr box match and will shoot that consistently 1/2 MOA average. Mine did not like box 175gr but if you hand load that wont be a problem. My hand load 175gr will now group sub 1/2 MOA all day long and i lend the majority of that accuracy to the rifle not me. The GAP-10 is a great rifle as well but i have no regrets getting the JP. Good luck on your purchase.

Here are 3x 3 round groups of Sierra Match King 168gr hand loads. Used OnTarget program for calculations.

 

[tewlman223]

I have a lrp-07 with good glass though just recently working with it. Just yesterday I shot multiple .5" groups at 100 yrds using 155 hornady a-max with 8208 powder. It is a load that JP recommended and it has not disappointed.

No problem. Hopefully that helps you a bit. I'm sure my inconsistency / lack of training could be a key factor, yet the general trends with the various rounds has been pretty repeatable.

I was chatting with one of my friends last night about expecting more from the JP and he brought up the same point you did: most of the really nice groups you see online are using hand loads tuned to the rifle. Have to say that did make me feel a bit better, but I still want to get a 0.50" group with some factory load.

 

[FALex]

well, if it's any consolation to you, I just got back from doing some load development (while doing the JP barrel break in deal). I was not shooting for groups like I was out competing, as I was most concerned with getting scope zero'ed and making sure I got everything right with the break in process. However, I just measured every group I shot and each of them was under an inch. ETA - all but one group were 3 shot groups, which I normally don't count for myself, but it was due to my load development, so today they count! HA! I have one 5 shot group at 300 that came in at 1.44.

You should also note that I am brand new to shooting a gas gun for precision endeavors. Obviously have railed tons of steel cased Brown Bear and Wolf with my 5.56's, but never considered precision work with a gas gun...until now. Getting used to the trigger's position is something I am going to have to get used to. It feels too close!

Sorry I can't help you with your bullet selection, mine is .260.

 

[ptrlcop]

Need some help from JP-LRP07 owners.....

Cold bore +4 from today. This is not a cherry picked group, it was the only 5 rds I shot.

Worth noting that all rounds are less than .1 mil from POA


ETA: this was 168 hornady tap

[webvantage]

Ok, so to give you some data for factory load, here is a target from shooting Federal Match 168gr. I got very similar results from Hornady TAP 168. Average group size of .6 MOA. A better shooter can do better than this i would think. I am still new to precision rifles and still learning.

 

[nombei]

nice shooting webvantage and ptrlcop!

interesting that your rifles seem to prefer the 168gr box match ammo too. wish i could get my groups to look like yours... i'll pick up some of the Hornady 168gr TAP to see what that does for me. i don't have any reloading gear, so for now i'll keep working with the factory ammo. just need one 0.50" group to make my day!

 

[997/2man]

My rifle shoots < 1" w FGMM, and maybe just a little tighter with Black Hills. But I'll have 4 touching holes and then take a vacation and send one that blows the group to an inch. It's all me, not JP's rifle.

Tried 4 diff. hand loads with 168s, 2 with 175s. O.k. results, nothing special, not for my rifle, buddy's ammo.

Hey, <1" at 100, I'm happy.


Here is a sampling:






And, my favorite.

 

[Stinger78]

I have an 18" LRP 07 I bought about a year and a half ago. It is my first/only AR-10 style rifle. On a scale of 1-10, 10 being sniper level skills I'm about a 1. I shoot half inch or better groups all day with FGMM 168's. These rifles are nasty accurate and make novice shooters look good

 

[EchoDeltaSierra]

My results from today, and it was the first time I've shot this rifle wearing winter weight jacket and gloves; it's grouped better and I blame myself. These were shot with 168 gr. SMK remanufactured ammo.
