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.

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.
