153atip Hornady brass 56gr RL26 215 primer COAL .30065" 2985fps from 22"

It certainly does up close(less than 300y) I haven't had to test it's long range terminal effects yet but the atip appears to penitrate a bit then open up....more like a Berger or Targex than a Amax or Eldm.
I hope they work at longer ranges....my googling suggests that they do.
Have shot steel out to a K which is about as far as I can go with single turn turret and stacked a nice group consistent with data.
I'm pushing them out of a 7 twist so the extra rpm may help expansion or not....

OK interesting, saw a few packs of the 153 for sale today but just grabbed another 147 pack, half the price is the kicker...

I hope the bergers shoot well, if they do I will need to track down another pack or two.

I only have 2217 as a suitable powder, if I can get 2900 I will be happy... but maybe only 2850.

Can Get superperformance but reviews are variable in terms of stability

My barrel will be 1:8 which should be plenty and might avoid the rumors of projectiles blowing up mid flight

Yeah while certainly more twist is going to increase the risk I wonder how much of it is actually due to roughened firecracked throats?

2217 should be good.

If you did it again would you stick with a 22" barrel?

How many rounds have you launched? Would be interesting to scope the barrel

I'd either go longer and no suppressor or 20" suppressed and probably a 8 or 7.5 twist...... unless some heavier bullets come out
I'd have to have a count up but at around 350 down the tube and throat still looks good but I don't thrash it on gongs either.
