Flat and very pleasant to shoot.
Will up it a tenth for a better
PF margin.

Lot of testing needed especially from "true" compensated
guns. But based on this initial test the 155 is a real stand out.
My gun configuration likes the heavier bullet and a 165 grainer'
might be optimum. But I can say with confidence the 155 is by
a wide margin the best "light" bullet major load I've tried.

You have that slow one in there at 1086fps, but it still makes 168+ pf.

Other than that, your lows are looking good for 170+ pf.

You could probably slow it down a bit, but I doubt you'd really notice it while shooting. If you aren't getting any signs of pressure...it might be a good idea maintain a cushion to make sure you don't go Minor.

Ok I will keep them right here then, I just switched from HS6 and 165 gr bullets, these 155's with autocomp are quite a bit louder, maybe sharper.

How are they working the comp? Is the gun shooting pretty flat?

Yes it is pretty flat I only tested them on a 12 " steel plate but I was double tapping it as fast as I could pull the trigger at around 10 to 15 yards and keeping it on the steel, my main goal was to chrono them so i did not test them much. They are a little flatter and a little louder than my 165's. I should have tried a bill drill on the steel at various distances that might be a good test of the load. with definitive results.

Have you guys compared this against N320? Thinking of switching powders in the limited gun.

155 Berry's Round Shoulder

155 Berry's Round Shoulder

155 Berry's Round Shoulder

7.0 grains
Avg: 1064 fps
PF: 165

155 Berry's Round Shoulder
Winchester Autocomp
7.1 grains
Avg: 1074 fps
PF: 166

155 Berry's Round Shoulder
Winchester Autocomp
7.2 grains
Avg: 1090 fps
PF: 169


155 Berry's Round Shoulder
Winchester Autocomp
7.3 grains
Avg: 1096 fps
PF: 170


Is it odd that even with 0.1 increases, the PF doesn't increase all that much? Must be reaching a limit of powder burn? The proof is in the shooting I guess.

FWIW and it's probably zip. I pulled a bullet on a Winchester Value Pack 165gr FMJ round. If that ain't AutoComp their kissin' cousins. The charge weighed in at 6.2 grains. I read, perhaps here, that it's more than likely WSF or some bulk commercial equivalent.

In case your interested.....as I'm sure you are <_< I am trying to duplicate the WWB round for my BRAND NEW JAGER COMPENSATED, FASTFIRE SIGHTED OPEN G35 (well, it's scored open) :) I'll post a pick...when I'm dang good and ready. Maybe tonight still.
