53gr Superformance out of 12.5” 1/8 ?

[jstone]

The stability should be no issue, but like MARKM said accuracy blows out of all the superformance I have tried. The superformance has problems with shorter gas systems, it's been a while but the burn rate of the powder should only be used with RLGS from what I remember. All the Vmax loads are usually great, if you reload there's a few more options.

Yea, I'd try the Vmax cartridges, they shoot very accurate and should be flat. Like Mark said the Super dog shit was just that. YMMV

2635 FPS out of a 12.5”. The drop is to within 1” the exact same as the .223 Speer 64gr GDHP at 300y. Thought it would fly much flatter.

I am shooting nice 0.89” 5 shot groups at 100y with it though. So that’s nice.

Should I try the 55gr VMAX?

Vmax has been great when Mark loaded them. I would def give them a try.

I shoot an 11.5" SBR with 55 V-max @ 2800 ft/secs. This load has accounted for many desert coyotes. What I found was how close it matched the reticle in my TAO1NSN ACOG if I substitute yards for meters! Never more than 1" off the POA vs POI.

The flattest shooting round in 5.56 is Black Hills 69 gr 5.56 TMK. FREAKINSHLY flat shooting with a long reach.

Not to hijack the thread but have you chronographed this load?

We chromo's some loads and they are in my Phone, being a dumbass I didn't note the 69 vs 77 loads. However I had 2827fps and 2843fps on another load. I think that was via 20 inch bolt gun.

I don't think we ever chrono'd the BH 69gr TMK 556 load.
