27.4 grs Big Game with 75 Amax at 2.48" COL. 2850 fps from 20" barrel.

Those fire form loads Steve?

You calling me a pussy? LOL. No. That's what we shoot in AI cases.

Maybe....

CCI 41, 25g 8208xbr, lapua case, 75 amax. 2.435" coal 3000 fps 21" 8 twist pacnor 3 groove. Sub 1/2 moa.

I think I need to get me some 8208xbr.

AR-Comp provides same speeds and better temp stability along with better consistency from lot to lot.

IMHO anyway.

CCI 400, 27.8 leverevolution, rem brass, 75 eld, 2.460" COAL, 22" mullerworks, 3015 fps.

I've got a case of AR-Comp. It's perfect for the 6x45 as well.

I like AR comp ok but 8208xbr has metered better, almost meters like ball but it's a small extruded like h322 or benchmark. I used to use benchmark a lot more but have grown to like 8208 a bit better for 75s. I have good lot to lot and great temp stability.

Still love benchmark with 50 or 53g vmax's.

I've read guys claiming 8208xbr and Benchmark is the same stuff.

Not the case?

Nope. I use different charges of each for a 50 gr Blitzking in .223. Also, XBR8208 is some of the cleanest burning powder I've ever used in a rifle. Benchmark is dirtier.

Shot this load tonight, or close to it. Topped with a 77 Sierra Tipped Match King. 2848 average ES 32. Pac Nor 3 groove 8 Twist @ 21" Speer LEO cases

50g V max or other with 28.0g of H335, Rem 7 1/2 or cci br4 is awesome to say the least.

I wanted to update this thread with some data for 88's and a few 75 loads as a few have asked me about them recently. These are from a 21" Bartlein.

Nice. That’s good stuff Hig. TY

Good stuff Hig, thanks

Your 75 data is about the same as mine,

I've been meaning to try the 88s in mine but it's a 1 in 8 so it may not work

It’s interesting that both FF to formed loads are 1.3 gr different.

27.5/Benchmark.....53 moly V max......Pac Nor 9 twist..Rem 7.5

Looks like 1.3 and 2.3 gr to me.

Thanks for posting your data!
