6.5 Mega done!

[Justice1327]

Might have a new set of rules in place..? This one will be less likely to puke unburned powder, and definitely will be an improvement in efficiency. Barrel will surely last longer.
Justice is going to find out, he needs to hurry up and tag out. I wish him luck quickly!

And thanks to him I'll probably be looking for another barrel before long, or at least a re-chamber for a certain 6.5 Max. It's already 28"

3 states to hunt in … it'll be next year before I get to this cartridge because I still have two cartridges to test in front of it.

Phil Phil Phil, efficiency and Barrel longevity. I couldn't care less, Not me just screaming bullets and smacking animals near to far, it's in range of the king 6.5-300wby. Barrel life is longer than I will live at 55 years old. It's a killer not a Prarie dog, PRS gun. Just a game killer extraordinaire.

With saying all that I do love the case of the Mega.

I'm wondering how fast a Berger Hybrid can be launched with predictable results.?

Barrel life isn't a real concern for me either.
But I do value somewhat well behaved cartridge designs.

Unlike my Dad who uses a 257STW 10tw and 100gr TTSX. But he's animals only. I shoot more than he does, except July and August usually, anyhow.

The one other 6.5 Mega I've heard about shot 156 EH at a comfortable 3250+ and "hit an 8" plate at will at 1100yds" as I recall. Serious medicine from any angle.

Distance corrected from 1200 to 1100yds*

That's smoking if true which i have some doubts, unless they are hitting huge pressures. I am working on my 6.5x300 with 153.5 and am at 3250+ with zero pressure. I finished up an additional ladder due to no pressure. Cant wait to see where she goes.
I am enjoying the 6.5 's more than I thought I would.

You are going to make me find out aren't you?

Great looking build, I'm a huge fan of the 6.5mm.
I have a 6.5-300WSM (Pronghorn) and mine is a 9 twist, so, 150g class is outta the question in that. Same goes for 2 264WM factory rifles.
I also have 8" twists in 6.5x47 (2), 264WM & 6.5-300 Weatherby.
How much powder volume increase is there with the 6.5 Mega case?

I am intrigued.

I have reached 3250+fps with both 142g/150g ABLR and 156g Berger in my custom 264WM based on the A191 reamer and custom throat/leade of my design 29.5" barrel, these are mild loads though.
My 6.5-300 Weatherby has a 30" barrel, so I expect 3400+fps with 156's/150's.

Cheers.

7 megs is 84grs according to Rich Sherman.

I have witnessed said 6.5Mega, as it belongs to a shooting buddy of mine. It is flat nasty. 28" barrel I think, but could be a 26".

Great looking rifle....Derek ain't a bad dude for wearing overalls 24/7.
