Need some input here as I'm finally doing a new build! In 2015 or 16, I bought my first precision rifle. In its current form, I have a MPA BA chassis with internal forend weights, the original Kelbly Atlas Tactical action (I run my bolt fast and hard, no issues with the ejector some have had in the past btw), with a ZCO 527 mounted in a Sphur. The barrel is a 26" Krieger with a Dn5 brake for PRS, and a KGM suppressor for p-dog hunting, etc. I'm shooting 140gn bergers @2850fps using 42.6gn of H4350 if that matters to anyone. Up until now, I almost exclusively shot Guardian Team matches, and really never got too much into PRS for various reasons until recently. One of the huge differences in team matches versus PRS is having that team mate spot and call corrections for you. Unfortunately my shot calling skills are severely lacking, lol.

So while I continue to hone my shooting fundamentals, which I know is 99% of my issue here, I might as well pick ya'lls brain on how I can buy myself a few points at the next match I shoot, haha!

For my next build I'm leaning toward the MPA Matrix Pro-II, with a Kelbly Prometheus action (have really loved my Atlas, but I'm open to suggestions). I really like the adjustable butt stock bag rider on the MPA, so that's a huge feature for me. I'm not sure how much I'll use it in PRS, but that will be money prairie dog hunting, which I do annually with my dad. Again, open to suggestions.

Admittedly, I'm stuck on a caliber. Yes, the top shooters are winning with 6.5CM's with 153's and 156's. See above on fundamentals. Plus I already have a 6.5CM, I don't want two. The 25x47 Lapua seems like an awesome choice. Its super accurate, but not light like a dasher, and still, to my knowledge is a significant enough reduction in recoil over my 6.5CM to be noticeable. My two hang ups are only Peterson and Alpha make brass, which is expensive and hard to get, and I already have a Short Action Custom sizing die for my 6.5CM. I could resize brass, but..... meh.... Handloading takes up enough time as is.

I spoke to a high level shooter who works for a particular company who was really fond of the 25CM. Great! Buy a bushing for my SAC die and call it a day. Well, did some reading on the hide here, and the consensus seems its recoil is the same if not more than my 6.5CM. Is slowing down a 25CM to 25x47 Lapua speeds realistic? Can it maintain accuracy with a reduced load? I get conflicting information on this. But it would be cool to have one die that rules them all!!!

Ok, maybe jump on the Dasher bandwagon, or a GT. Same issue as the 25x47. New dies, but also new magazines. Can't modify existing mags bc those are for my Creedmoor. Plus there's a tradeoff IMO. Dasher, less recoil, but more wind correction. 25x47 is the opposite. Figured managing recoil is an easier fix than my wind reading skills.

6CM, high speed, good wind ballistics, but a barrel burner. Not remotely interested. This sport is expensive enough.

So there you have it ladies and gents, lay those opinions and words of wisdom on me.
 
Worrying about having 2 different 6.5CM rifles is like worrying about having 2 different gasoline powered vehicles. Pretty soon a guy will be choosing based on color. 6.5CM works and you are set up for it already. Ignore my advice if you have too much $$$ and are just trying to spend some.

Lol, fair statement, but just wanted to try something different.
 
If I’m shooting custom rifles with a ZCO, I wouldn’t be too stressed about buying some brass and dies, just personally.
You’re not wrong, lol. But damn those SAC dies are expensive, but soooooo good. And so many other things I could spend that money on! Like maybe an over priced bipod, or a fancy chrono, or annealer.
 
If the goal is to place higher up in comps, that money is MUCH better spent on training.

If you just want a new rifle (and nothing wrong with that), then go ahead and build one. Make it different than your first one. Nothing wrong with a Prometheus action. You already have a 6.5 CM, why not something different like a 6BRA or other cartridge? Perhaps try a different chassis or a stock like a Foundation. Mix it up.

Shouldn't have a problem running a 25 Creed at 2700fps ish.

Could try shooting a lighter bullet it in your 6.5 and slow it down just to make sure that's the answer you're looking for.

I'm building a PRS rifle and no way you could talk me out of a Dasher.

Definitely agree on that, and more importantly, putting in the work dry firing more than anything. But I am building a new rifle regardless.

So yeah, just looking for opinions on any and all. If you’re a fan of 6BRA, why? Same for Foundation, MDT, KRG, or whatever else comes to mind? Actions too. There’s a ton of info out there, but I’m looking for real world opinions, not a sponsored pro, or YouTuber. Thanks for the reply!

What do you love about the Dasher so much? It’s obviously #1 on what the pros use for a reason. Any drawbacks in your mind using such a relatively lighter bullet?

I’ve thought about slowing down the CM, and even going lighter as well. I read an article about detuning a round too much led to inaccuracy bc the case was not at or near capacity. I’m sure testing could sort that out when I find the time.
 
Is a new rifle in whatever caliber going to help you call your shots ?
You have a rig you're familiar with suited for shooting PRS right now.
Training with someone who can show you how to call your shots would be a better expenditure of your money.
