[Doc68]

Thanks man. Much appreciated ?

 

[XTREM HTR16]

Is anyone using Lapua 7mm-08 brass, if so could you give me a reading of your necks with a bullet seated. I just want to compare it to mine.

thanks in advance.

just loaded some up this weekend
virgin Lapua brass with 150 Scenar = 0.3140
1x fired, resized Lapua brass with 150 Scenar = 0.3130

does that match yours?

Good info guys thanks for sharing. I am working on putting components together while my rifle is being built.

I'm actually using Lapua 308 brass that I run through a 7mm--08 FL sizing die. I thought I was gonna have to turn the necks on the brass, that's why I was asking myself. But it seems I'm good to go for now.

Anyone tried the Berger 190 hybrids yet in a 7mm mag?

Good to know. I’ll prob just buy a box of the 7mm-08 Lapua brass and go from there but I think yalls numbers will jive with what I’ll be looking at.

 

[Doc68]

I found the Lapua 308 brass is about 20-25.00 cheaper per 100 piece box than the 7mm-08 Lapua brass and all you have to do is run it though a FL sizing die.

No neck turning or anything? Trimming?

 

[Doc68]

Nope, just straight through a 7mm-98 FL sizing die.

 

[sierracharlie338]

Very interesting I may have to give it a try.

 

[Doc68]

It's worth it in my book. Ten minutes worth of work for cheaper quality brass

 

[Doc68]

I have a neck diameter of .0315 and OAL of brass of 2.015-2.018

 

[Markhammett]

I’ve had real good luck with varget and 139 gr sst out of my custom 7mm-08.

RE 7mm loads
I have a custom LH Remington 700 hunting rifle with McMillian, and Jewell. It has a, lija 24 inch barrell with a 1N 10 twist

Here is 5 shots out of a cold barrell at 200 yards. Top right is first shot.
should I be happy with this group?
My son did the reloads as he shots in 600/1000 yard match.
he has other loads to try but what are the thoughts here

Forgot to add that it is using 168 bergers and we are trying 140 Berger BLD also

 

[Doc68]

1/10 twist??? Most are 1/9 or 1/8

 

[Mightyman]

Yes it is a 1n10 ias I had it nade with that and a Lija barrel
Thanks

How heavy of bullets can you shoot through that twist.

 

[RogueTanker]

Took my 7/08 ackley out to start burning thru some 180s. 2 shots at each charge weight. Neck at .3185 so I can size 308 with no turning.

26" tube
1/9 twist
H4350
180gr eldm
Non ffed LC LR 11 brass

44.0 2595 2582

I always wondered how fast 7-08 was with 180’s

 

[RogueTanker]

Fully ackley'ed, I can get 2700 easily.

 

[RogueTanker]

Went back for round 2. This time I used the fully formed Ackley brass.

26" tube
1/9 twist
H-4350
180gr ELD-M
formed LC LR 11 brass
loaded at 2.945

45.4 2585 2593

46.0 2611 2616
46.2 2628 2611
46.4 2661 2617- The 2661 shot was the only "flyer"
46.6 2643 2637
46.8 2656 2657- Still no signs of pressure.

 

[Doc68]

So here is a good load for my rifle.

RPR
27" barrel from preferred barrel blanks

.547 MOA at 100.

47.4gr of 6.5Staball powder
CCI Large Rifle Primer
Lapua 1x fired 308 brass formed into 7mm-08
168gr classic Hunter bullet
30 thousandths off lands.
15 shot average 2782fps.

 

[Mightyman]

Thanks for the help

 

[Mightyman]

Still looking for best suggested loads;
24 inch barrel
1-10 twist
Thanks guys

 

[RogueTanker]

Varget and 139s are easily the most accurate load I've ever shot. 5 shots stacked on top of each other. Those should stabilize well in a 10 twist.

Try 41.5-43 gr

 

[Mightyman]

Ok thanks!
now that’s what I am looking for I will try that..once I find some Varget!

Re: Loads for 7 Rem Mag

I am debating between a 6.5 284 and a 7mm Rem Mag. Ballistically, the 7mm has got my eye, but I have been warned about the recoil. How do these loads feel. I will be firing about 50 rounds per competition.

Thanks

If you have a balanced rifle the recoil can be less than a .308 with the 7 mag. My Fierce Edge is crazy comfertable to shoot with anything from 150 to 175s. It has less felt recoil than my .308 Browning Hells canyon had. The rifle makes the difference; lesson learned from Savage Axis 30-06... 180gn x 23 rds = ticked off shoulder.

 

[clcustom1911]

Rifffle: 7mm RemMag Tikka T3x Lite, 1:9.5, 24", factory configuration dropped into a Manners T4 MCS, CDI bottom metal. About 1500 down the tube.

RP Brass (3-4 firings, Lee Collet Die neck sized.
FED 215M primers
68.5 gr Reloder 26
168 Berger Classic Hunter hybrid
.020 jump

Lee dies in my old Dillon RL450

I think I did something right ?? 106 yards shooting from this position:

Made an adjustment, Changed point of aim, this happened:

Velocity.... no clue. When I shot Berger VLD 168's, Sierra 168 Matchkings it was 2985-3000. I suspect these 168's are moving with about the same sense of urgency.

 

[clcustom1911]

How heavy of bullets can you shoot through that twist.

168 would probably be the heaviest. My Tikka is 9.5 twist and can do well with up to 175's.

 

[millertime2]

Anyone try 190 Atips yet in 7RM?

edited Update: I tried some got them around 2945 with 67.7 grains of RL26. No signs of pressure gonna work up a little higher and see if I can find the next node or pressure signs. If I can get them up to 2960 safely they would gain me around 1 mil of elevation and .1-.2 of wind better than 180 ELDM’s at 1760.

 

[TheBoctor]

Figure I'd throw in some of my 7RM pet loads. Some of these are redlined so explore at your own risk.

For 7RM 26" Bartlein 1-8"
195 Berger EOL- 71.7gr RL33, GM215M, Norma Brass, 2.660" CBTO (.020" jump)- 2792 fps, ES 15, SD 7.3
195 Berger EOL- 66.5gr RL26, GM215M, Norma Brass, 2.660" CBTO (.020" jump)- 2904 fps, ES 12, SD 4.0

7RM 26" Christensen 1-9""
155gr Hammer Hunter- 66.3gr RL26, GM215M, Norma Brass, 2.726" CBTO (.025" Jump)- 3158 fps, ES 5, SD 2 (only 4 loads thrown before i ran out of bullets, hope to prove this one out when i get some more bullets in).
180gr Berger VLD Hunting- 65.8gr H1000, GM215M, Norma Brass, 2.705" CBTO (0.020" Jump)- 2932 fps, ES 11, SD 6

 

[wpeach1912]

Would 2700-2800 fps with a 24" 7-08 and 162 ELD-Xs out of a short action be reasonable? The barrel just went out on my Savage 6.5 creed, and I am thinking about rebarreling it with the 7-08.

 

[Doc68]

Very reasonable. I had a 27" before my surgery that was getting 2850-2875 for the 162s.

 

[AZgeek]

Anyone tried the Berger 190 hybrids yet in a 7mm mag?

Very limited testing but yes.

70.1gr of WC857 surplus, 2736 fps, 558yds=2.7mils, 24" Remington 700

 

[Rickt301]

Hunting load for my Model Seven, 18 1/2" barrel

7-08

Winchester brass
47.0 grains of H414
145 gr. Speer BTSP
CCI 250 primer
2749 fps

Work up, use a mag primer. Load shoots 5 under 1 1/4 inch in my rifle. Sudden killer on deer and feral hogs.

 

[BrienM]

Is anyone burning H1000 with 7mm rem mag behind 184bergers or any other weight in that area say 180-190's?

 

[nightman89]

I've got a Remington 700 in 7mm Magnum with a 26" barrel. Wanting to shoot 162g ELD-M/ELD-X/SST bullets. I have Reloader 26 available to me. Anybody have a good load with this combination?

 

[FuhQ]

I've had over a dozen different 7mm rifles (all cartridges from 7mm-08 up to 7mm RUM) over the years, and the 7mm RemMag has been my go-to deer cartridge for almost 20 years. Hard to beat. Will always have one in the safe, and most-likely will always be my go-to deer cartridge.

I have 2 Fierce rifles a 6.5 Creedmoore that loves 143g Hornady ELD-X factory ammo. It’s probably the most accurate gun I have ever owned. Just got a 7mm Rem Mag in a Furry as well. With the current ammo shortage I haven’t found anything it really likes yet.

I would highly recommend learning to reload your own ammo. That 7mm RemMag will REALLY shine with handloads. I've been shooting and hunting the 7mm RemMag for almost 20 years, and it wasn't until I started handloading for it about 10 years ago, that things really hit a new level with all of my rifles. No factory ammo I've ever shot will outshoot any of my handloads.

 

[Highbrass]

Been experimenting with 7-08 loads in a Rem 700 with a 24" Criterion Remage 1~9 twist. It seems to like about 40.5 Gr Varget & 162 ELDXs. That load bumps into 2700FPS & shot extremely well to 500 Yds. still Playing with it. Started seeing pressure signs @ 41 Gr
I went thru the last of my ELDXs but have some 162 AMXs on the way.
Wanting to try them in my 7Rem Mag with Criterion Remage 1~8
I have several powders to try gonna start with MagPro ...Just because I have a lot of it ...

Get you a 1:8 twist barrel for the 7mm-08, and try some Berger 195 EOL's... Folks think I'm crazy, because I have been shooting Berger 210 and 215's for my .308 Win for nearly 10 years. The muzzle velocity isn't very fast, but the amount of energy and drift it maintains is unparalleled downrange. The numbers don't lie.

One day I will build another 7mm-08 with a 20" 1:8 twist heavy barrel just to shoot the 175-195gr bullets.

I would have gotten a 1~8 708 if it had been available in a Remage Pre-fit. I was told that 1~9 was the fastest they made (that was available now)

Check with Preferred Barrel Blanks. I ordered a Remage barrel 1-8 twist with R5 rifling for a new 7mm Rem Mag build. Expect a Looooong wait if you ever go that route.

I do reload. Out of curiosity what’s your favorite Elk bullet?

We don't have Elk in Alabama, but if I had to choose one based on what I know, I'd recommend the Berger 195 EOL... But you will need a 1:8 twist to stabilize it.

Favorite elk bullet 28 nosler 195 Berger, 7 mag 175 accubond long range, 7mm08 168 accubonnd long range, my 7sip 175 accubond long range and the 7 wsm is 180 vld

So this is the route I went. I actually have an 18" proof 1:8 twist chambered in 7/08 and planning on running the 175's. Would be interested in any information you have. Plan on working up a load soon and trying to decide on the right powder. I have plenty of Varget and H4350. I have 8lbs of IMR4895 as well but not sure if that's gonna work. Sorry to revive an older post.
