Painless load development (mine)

I think that would work.

An 18” 6.5-7 PRC shooting the 147 around 3000 would be a handy rig. I’m not sure if that charge and short barrel would play well with most suppressors though. If the OG 6.5 doesn’t have a barrel restriction, 22” overall barrel length suppressed would be awesome.

Tested 109 LRHT’s in the SAAMI 6 creed with 42gr. H4350. 2.857 COAL. Or about .020 off.

They aren’t very far down in the case neck (bearing surface is maybe 1/2 way down), so I single fed 5 and then mag fed 5 to see if it would make any difference with dispersion from the bullets hitting the feed ramp and possibly getting a little runout. It didn’t affect anything.

10 shots overlayed into a .57 MOA group with an ES of 28.

No actual load work, other than testing N555 as well, which didn’t shoot as small of groups but did have a lower ES. I’ll personally take the smaller groups vs. lower ES all day.

This is also a 26” carbon benchmark and the gun weighs 10lbs 4oz.

H, have you shot a critter with those 109 LRHT’s yet? I’ve got a 7 twist .243 that likes those and I’m curious how they perform on meat.

I haven't yet. I killed a coues deer at 500 yards with the 144LRHT and it performed very well. So I know the bullet style is capable of nice wounds, just don't know if it's optimal for them.
