Unfortunately most folks can't get LE ammo, so that most-likely eliminates that solution to his problem.

However, the awesome thing about most all Ackley Improved chamberings is that you can shoot factory ammo in them and fire-form brass. In a custom rifle, you should still get MOA accuracy out of factory rounds that haven't been formed yet. And out to 500 yards, that's only 5" groups, which is more than capable of killng any medium-to-large game.

When I was fire-forming brass for my .25-06 AI with Nosler 85 BT's, I was getting fairly consistent 1/2-3/4 MOA groups out of un-formed brass that was still for factory chamberings. My .30-06 AI was the same way, and so was my .300 Ackley Mag.

This is with a .30-06 AI w/ a 26" 1:12 barrel, pushing a Berger 185 VLD around 2,861 fps MV.
I like your set up.

It looks like a factory rifle, but it's a custom build, I can assure you. I haven't gotten my load 100% dialed-in yet, but I'm hovering between 61-62gr of IMR 7828 SSC powder, and at 62gr, according to Quickload with my rifle's specs, should net me 2,861 fps MV.

I'd bet that the whole gun/scope combo probably weighs 10 lbs.

That is what my 7mm RM will look like when I wear out the factory barrel. Right down to the bolt handle. Perfect gun for the OP.

So then you haven't chronographed it yet? Quickload doesn't really mean anything. I've had the same exact hand loads in the same calibers go 150 fps in two different rifles with the same barrel length. You just don't know til you let bullets fly across those two little photo eyes hooked up to a timer. 3861 fps with a 185gr from anything based on the 30-06 case is a stout assumption of speed to say the least. So I see no relevance in your calculated long range velocity or energy until the speeds are proven.

I remember my father thinking he was pushing his bullets 200 fps faster than the manual listed because he was 3gr over max charge. Well when I chronographed his load for him, that assumed 3300 fps was actually only 3060 fps. He wasn't getting a complete powder burn. And the funniest thing was that the max charge in the manual said he'd be going 3100 fps with 3gr less. He wasn't even doing that! so you see my point I'm sure...

Not trying to offend you at all, as you seem to want to help everyone on here, but I believe advice and data intended to help others is best served based on proven facts, not assumptions of possibilities.

PS: That ought to make a really nice hunting rifle

I said 2,861, not 3,861... That would be obsurd. I have not hooked my MSV2 onto it yet, but might do it this weekend if I'm off on Friday.

Powder burn is supposed to be 97.1%, if i remember correctly, so I'm not lacking much from a complete burn.

I do understand facts are facts, which I will have soon, once I get this load developed. 2,861 is pretty feasible. It's a 106% load compression.

Re: Do I really need a 300 WM?

Sorry. I meant 2861 fps. Typo.

Even if that speed was possible, another unknown factor is whether or not a person may have to sacrifice accuracy to achieve that speed? Maybe you will, maybe you won't. Then again, maybe it will be most accurate at max loads. Don't know.

I do know for a fact that speed is not everything. I can push the 250gr Berger VLD in my 338-375 Ruger at over 3000 fps from my 26" Brux barrel, but I found the best accuracy at 2925 fps so that's where I left it. Regardless of being 100 fps under it's potential, it hammers the hell out of game.

I hope your load does turn out like you plan and would be interested in your data once it is discovered.
