I've been debating between the 123 and 139 scenars. I don't have any loading supplies for 260 yet and was hoping to find a good mid-range bullet. What are you guys using? I am not stuck on the scenars and will try anything

Re: What 6.5 bullet for 600 yard F-Class?

Check out the Hornady 140 AMAX. We shoot them out to 1000+ and they are very accurate. Also they are about $12 cheaper per 100 than the Lapuas.

That is sometimes true but not in the case of the AMAX.

TDH, I would recommend buying a box of each bullet you want to try and see what gives you hte best performance before buying anything in bulk.
 
Re: What 6.5 bullet for 600 yard F-Class?

F-class use I'd suggest 140 or 130 Berger, 140 or 130 JLK (bit harder to come by), 142 SMK, or 139 Lapua.

140 A-max is a good bullet but seats deeper in case, going to cost you some velocity and has lower BC.

Dedicated F-class rifle I'd go with highest BC bullet that your rifle likes. What twist rate barrel is on your rifle?
 
Re: What 6.5 bullet for 600 yard F-Class?

I was scanning the Litz book while down at Nomad's house and unless I read it wrong his tests showed the 140 AMAX had a higher BC than the Lapaua 139s. Anyone have has book handy to check?

Also with a mag system you can load them out longer so no problems losing any velocity. I have had them loaded to 2870fps with no pressure signs in my 6.5 Creedmoor.

Don't have the book, but I'm thinking the 140 A-Max is about .550. I think the 139 Scenar is over .600; .615, maybe? Memory ain't what it used to be.
 
Re: What 6.5 bullet for 600 yard F-Class?

The 140 is higher than that. I believe Litz listed the 139 at around .585 and the 140 AMAX at .610. That's from his testing. The 140 is listed at .550 but I have always used .585 and been on.

Anyone with Litz book want to check that?
 
Re: What 6.5 bullet for 600 yard F-Class?

Just called Nomad and had him check his Litz copy and here's the BC info:

139 Scenar
3000fps .598
2500fps .574

140 AMAX
3000fps .626
2500fps .602

Hornady .264 140 A-MAX .287 .550

Lapua .264 139 Scenar .284 .615

I used .615 to calculate and it was on from 100 to 600.
 
Re: What 6.5 bullet for 600 yard F-Class?

Yes those are the published numbers but from my shooting of thousands of the 140 AMAX I have found that they are higher than .550 and Litz has confirmed that with doppler testing.

Like I said I had used .585 with the 140s and found it on to 1000 yards. So with the velocities of the Litz numbers, the BC number I use would work out on average at the velocities I run the 140s at, about 2800fps at muzzle, and the BC decreasing as velocity drops down to about 1400fps at 1000 yards. The small difference in BC numbers between the .585 I use and the Litz numbers, which are over .6 at 2800fps, at the closer ranges wouldn't be seen but at distance it would but as i already said the BC would drop as velocity does so it would average out correctly for people using one BC number in their ballistic calculators as opposed to those using multiple velocity BC readings.
 
Re: What 6.5 bullet for 600 yard F-Class?

F-class a 140 A-max is not going to hang with a 140 JLK or 140 Berger. A-max is a great bullet. If you are going to play the F-class game there is no reason to leave extra BC at home in the bullet box.

Now, if you are just using F-class as cross training for your tactical rifle than use same ammo as will be used for tactical match. That is the only reason to run a 140 A-max in an F-class match.
 
Re: What 6.5 bullet for 600 yard F-Class?

140 Berger or JLK will work just fine with an 8.5 twist barrel.

Any idea of how much free bore in your chamber?

Berger 140 VLD BC .612

JLK 140 VLD BC .630

How is using the AMAX with it's BC in the same range as the Berger leaving BC in the box? Only thing it's leaving is more money in your pocket to buy more bullets.

Also with the polymer tip it will keep the BC more uniformed without having to trim the meplat or point them like standard HPBT bullets.

TDH, if you want I will send you a box of 140s for free. That's how strongly I feel you will like them and they will perform for you. Drop me a PM with your contact info.

I'll certainly take your experience at face value as I've never shot an A-Max. Frankly, I was surprised that the Lapua BC was so close to the published number. Actually shot .5 MOA higher than the program indicated.
 
Re: What 6.5 bullet for 600 yard F-Class?

I just bought 600 JLK 140g bullets if that lets you now how I am leaning. Only <33 caliber bullet with a higher BC (G7) is the 180g Berger in 7mm and and the 240g SMK in 30 caliber.

Cost and availability are factors too I understand.
 
Re: What 6.5 bullet for 600 yard F-Class?

Thanks for all the input guys. I appreciate the debate and good info. It will be strictly F-Class. We don't have any tactical matches close to where I live and my rifle is setup more for F-Class and is not ideal for a tactical match.

Just for info purposes the rifle is a Badger M2008 with Bartlein heavy varmint barrel at 28". I'm debating bring it down to 26".

Barrel is 1:8.5 twist 4 groove.
 
Re: What 6.5 bullet for 600 yard F-Class?

I own the Litz book (which I highly recommend BTW) and can list a few BCs here. I'm going to post G7 BCs since this is a much better representation of these VLD type bullets for this application.

Berger 140gr VLD = .313
Hornady 140gr AMAX = .299
JLK 140gr VLD = .327
Lapua 139gr Scenar = .285
Sierra 142gr MK = .301

So yes the Lapua seems to be the least aerodynamic of the bunch with the JLK in the lead. I've also placed an order for the JLK 130gr (same profile as the 140gr) to play around with as well.

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: TDH</div><div class="ubbcode-body">It will be strictly F-Class....I'm debating bring it down to 26".</div></div>

Don't go shorter than the 28" for strictly F-Class...
 
Re: What 6.5 bullet for 600 yard F-Class?

I shoot the laupa 139s right now. But I'am going to experiment with the Jlk 140s and the 140 Amaxs. The JLKs are hard to get but are great bullets. You have to order larger amounts and at the right time. The Amaxs you can get pretty much anytime and they are cheaper in price but not Quality.
 
Re: What 6.5 bullet for 600 yard F-Class?

current load-123 gr scenar, 43.7gr H4350, 2.820" COL, fed 210M, RP 260 brass, 1in 8twist 26" krieger roughly 2975 fps

When Terry Cross sent me my rifle he had recommended I use 139gr Scenars with 47.0gr H4831 for a better load density but I am a cheap bastard and went otherwise as many have done. I still score decent even though my ES and SD's are higher. I thought I would start with a bushing die, then go to Terry's suggested load after I run through my 123's. I am running a factory trigger and will upgrade someday. When I retire my 260 R-P brass I am going to go to 7-08 W-W brass and neck down to 260.

As you can see I am the only guy that has responded to your thread that uses anything other than the 139/140/142 gr bullets. That probably means something...
 
Re: What 6.5 bullet for 600 yard F-Class?

140 A-max has less BC than Berger. JLK, which I listed as my first choice/suggestion, has even more BC.

140 A-max "...in same range..." still has less BC than JLK or Berger. Less is less, that is how you are leaving BC in the box.

You do a great job as a sponsored Hornady shooter of pushing product. I am a fan of Hornady bullets but I also like to pick the best bullet for the job.

Look at what bullet is being used by shooter that finished in top 10 or top 20 at USFCNC from last couple of years. That'll be a bit of an indicator.

Unless chamber has been cut with a fair bit more freebore, the A-max is going to seat deeper in case. Unable to push the A-max to same velocity as JLK. If you have enough freebore to seat the A-max where boattail/bearing surface junction is right at neck/shoulder junction, than the JLK wouldn't be as good a choice.

I don't just push them because we are sponsored by them but because we use them very successfully to win matches. I won't use something that doesn't work. I find them to be an excellent and very accurate bullet and I make no secret of my sponsorship as I put a huge Hornady banner in my sig line and will tell anyone who asks. It's not a reason to disregard my recommendations or experiences with the bullet and what it can do. Also so you know I was using AMAX bullets before I was sponsored by them after using others.

I have used Berger bullets in other calibers in the past and they very good bullets as well but I didn't find them anymore accurate than the AMAX bullets and they cost more.

What velocities are you getting from your 140 JLKs?

I think the OP will try different bullets in his rifle and use what works best as anyone should but writing off a bullet like the AMAX because it's not from a company that is held as the top of the line like Berge or JLK is a mistake.
 
Re: What 6.5 bullet for 600 yard F-Class?

I don't recall saying the A-max was a bad bullet. I said for dedicated F-class rifle it wouldn't be my first choice. I also asked how much freebore was present. Have enough freebore present to optimize rifle for 140 A-max / 142 SMK / 139 Lapua, going to be a bit more jump than I'd want for use with JLK.

Friends rifle in 260, had a short throat which limited OAL to 2.740" for 0.010" off rifling with the 140 A-max. JLK in that chamber was much better match, Berger was better but not to same level as the JLK.

140 A-max 2690 fps
140 Berger (old vld design, not newer BT design) 2800 fps
Accuracy loads, not fastest I could push the bullet. Problem with the short throat, caught between powders. Get pressure signs with Varget, couldn't get enough 4350 in case.

Can't find my data book with the JLK chronograph data for that rifle, do know the JLK ran faster. I've not gotten a Berger 140 BT in hand to measure, appears from pictures to be closer to the JLK.

140 A-max for tactical rifle is right in the thick of things. I'd not hesitate to suggest a 140 A-max for taking an antelope, deer, or yote. A-max shoots well, just doesn't hang with the JLK or Berger in dedicated F-class rifle in 6.5mm.

You musta missed the parts where I said I liked Hornady bullets.
wink.gif

Never wrote off the A-max, said there were better bullets for F-class.
I use a lot of Hornady bullets, really like the 75 and 80 gr A-max with 223, 87 V-max with 6BR (10 twist barrel, coyote rifle), and 178 A-max with 308. Got a fair number (2.5K or so) of 208 A-max to try with 300 SAUM and WSM. I'm a fan of Hornady bullets because Hornady bullets do work well.
 
Re: What 6.5 bullet for 600 yard F-Class?

I use the 140 in the 6.5 Creedmoor which has a shorter case than the .260 and the rounds are loaded at 2.800" OAL. When reloading I can get 2850fps with 43grn of H4350 with no pressure. No problems fitting the powder or bullet in the case. That load is my accuracy load and is sub 1/2 MOA to 400 yards which is the farthest I have shot groups with it to but I have shot it further on steel and it stays tight. The AMAX doesn't mind a little jump and still shoots accurately.
 
Re: What 6.5 bullet for 600 yard F-Class?

I'm going to try the Amax that Rob has so kindly offered to send me and I'm also ordering some of the Berger 140 VLD's. The JLK's are a little more than I was expecting to spend, but I might try them eventually.

I really appreciate all the debate and info and if you guys want to continue, I'll be happy to learn from you.
