6mm that would be good for competing in f open.

I think the low node trend came about when people heard Jake V was running his comp gun slow so the bullet stayed in the air longer (trace.)

If anyone knows any other reason to do so, I’d like to learn.

That sounds good... and I don't know much about a usual course of fire in PRS- but we're talking about a tenth of a second at 1000 yards... if you couldn't see the trace at 3000fps you aren't going to see it better at 2900

I think you can if you’ve paid your membership dues on a certain forum.

Joking, of course.

I don’t know why you’d take a 3100 fps cartridge and run it at 2800, but lots of them are doing it. I got nothin, maybe we are the weird ones.

 

[LVLAaron]

I was joking today that PRS is the crossfit of shooting sports. Someone did well shooting it slow, so everyone will. Someone shot well with a purple stock, so everyone paints their stock purple.

@LVLAaron I was off today and tried some 88 Bergers with N140.

I did a pretty basic seating depth test just in and out of the lands in .003 leaps. Ended up at .006 off. I ran them from nearly frozen to blazing hot and it shot well with several easily identifiable nodes.

I’m quite fond of the cartridge. I don’t think it’s the magic potion, but I don’t think that about anything. I think anything between a BR and a 47 can be competitive.

the ctg is not what is competitive--its the SHOOTER---Roger

I believe it's more about barrel life than the slight amount of wind drift you gain from 3k FPS. What advantage do you gain by pushing any cartridge to its pressure limit, is it then more accurate?

 

[LVLAaron]

I'll buy that.

 

[JEFFPPC]

Most of the guys that I shoot with are trying to slow down the GT to below 2,900 fps.
Been shooting a straight 6BR for many years in F-Class / PRS and mag fed flawlessly.

The 6 improved cartridges, dasher, brx, bra whatever, can be pushed to close 3100, but in my experience at 3000 accuracy degrades. 2970 to 2990 seems to be a sweet spot for me. I have talked to other longtime 6 shooters who say the same think. Accuracy tops out at just under 3000.

 

[eddief]

6BR, 6Dasher or 6GT are all your best choices for PRS. 90%+ of your top guys in open are going 2760 to 2850 speed wise.

For F-Class I would work up a faster load to play the game. The two are vastly different

 

[Evan]

So Kelbly F- Class Panda has 7 months lead time. Bat model M, is another I was considering but haven't called out there yet. Any others I should be considering? I think I'm just going to strictly build a rifle for F Class.

Jim Borden. He makes a short action repeater specifically for 6BR size cases. If you want a single shot, the Rimrocks are excellent. Buy the trigger from him and he'll time it up perfectly to the action for you. I have a couple Borden rifles, and will likely have more in the future.

Yeah I really gotta give this some thought and research and make a decision soon. I would like to be sending rounds down range by 2024 at the latest.

+1 on the Borden rimrock. They are smooth as silk.

 

[WildBill3/75]

6br/bra/brx/dasher would be my choice for 1k and in.
Bra is a br with an Ackley improved shoulder.
Brx keeps the br shoulder and blows the case forward.
Dasher gets the Ackley shoulder angle and blows the case forward.

6br or bra would be the easiest if fire forming scares you. You can just load them and shoot.


So many good actions out there. Go with what you like.

 

[Webster]

The BRX just a longer neck over the BR and bigger angle correct?

I have one. Shorter neck. The shoulder is blown .100" forward reducing neck length. I think it's the same shoulder angle. Will try to get a picture posted.

Here you go. BRX with a 109 Berger .020” off in a .140” FB chamber. It performs quite well at 1K. Occasionally giving the 6.5’s and 7’s a good run for their money if they don’t do their part reading wind.

 

[BORGY76]

Ive decided on the brx. Panda action will need to be ordered, Bruno's has a Bat model M in stock. Either way im going to be waiting on components in some fashion, so im kind of leaning towards the Panda. Stock I still haven't gotten anyone on the phone to discuss specifics, figure for the money, might as well get EXACTLY what i want.

F-Open, weight limit is 22 lbs. Trying to figure out max. length i can go on a straight or heavy palma contour. Does the 22lb limit include front rest as well? Im thinking about getting my own reamer and have a smith do a couple barrels at the same time. Then when i get time, play around with doing a barrel on my own.

I have some new lapua brass, primers, barts 105 Hammers on order. Was thinking of getting some bergers to play with as well.

About the only thing i can think of to do ahead of time, is deburr my flash holes/inspect and sort brass. Suppose i could also sort primers too while i wait.

22 Lbs is rifle/scope, the rest is not part of the total weight. .140”-.150” free bore will work great with anything from 105-110 and a .272” neck. Don’t waste your time with de burring flash holes with Lapua brass. Reloader 15.5 and 16 or Varget with CCI 450’s. I highly recommend a 7.5” twist for versatility. I’ve never seen a picky BRX. They are all super easy to load for and a real pleasure to shoot. And the days you beat the 6.5’s and 284’s are really satisfying, lol! I had one of those yesterday..

 

[Bottom Fodder]

I shoot a 16” 6 BrX (poor man’s dasher) with 107’s at 600 and 1k no problem. Stays super sonic for shot mark at 1k
