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.

My old load of h4350 and 95 NBT for my 243 shot like shit after bedding, floating the barrel, cutting to 18” and threading (it never shot great, about 2moa at 100 for 10 shots). It was now 2.5” plus at 100. After reading this thread and eliminating most of my case prep methods, I chose two top end loads from hodgdon’s website, one with staball 6.5 one with h414. I loaded 5 of each just to see if they showed promise. Staball shot better than the h4350 load but still 1.5” for 5 shots at 100. H414 put all 5 into .6” at 100. I loaded 10 more and shot the same target, putting all 15 shots into 1.5”. The load clocked 2880. It’s looking plenty good to me, so I’ll load up another batch and shoot some steel.
I appreciate this out look on reloading and avoiding the incremental changes. It was pretty obvious which load was going to shoot looking at the 5 shot groups side by side, only difference being the powder.
