Just shot the 61gr load with .100 jump and it has more pressure than my .002 jam. 3505fps with nice shiney ejector mark.

You better be careful. That place sounds like it could go up like the shuttle. lol

Smokeless powder is pretty safe stuff as long as it's not contained in a vessel that can pressurize. The cans of black powder I have would be much more scary.
I think I'm done testing gonna go with the h100v. Gonna freeze a few and see how much speed I lose.

I've got a 243-378 WBY mag. I'm waiting for the .243AH bullets so I can reach the 6,000 ft/sec record. I gotta get it right fast because the barrel life is about 50 rounds.

4300 is as fast as I've got. 243wssm with a 55 gr. Literally exploded a ground hog with it.

Going to run both a bit higher after the rain.

So did some testing with Superformance in the 6.5 PRC, went from 57.6gr up to 61.8g and velocity went from 3153 to 3420 with some light extractor marks and a heavier bolt lift. I'll be giving the 61.2 to 61.5 window a test as the velocity spread was only 3396 to 3402. The whole group was roughly 1.5 MOA but the first 4 were low while the remaining 11 went sub 3/4 MOA.
I also did more testing with StaBall 6.5, did the same load as last week but the groups opened to 1 MOA instead of sub 1/2 MOA. The weird thing is that the velocities seem to split between 3320 and 3360 with an odd 11 o'clock string even though they are all 59.3gr. I have the Lee FCD on order so I will have to try that and see if it helps tames the odd results I seem to be getting with StaBall.
Also I've been updating the document so if anybody else wants to add their load data please feel free.

I have noticed with staball 6.5 when you get to upper end loads it will get real jumpy with velocitySo did some testing with Superformance in the 6.5 PRC, went from 57.6gr up to 61.8g and velocity went from 3153 to 3420 with some light extractor marks and a heavier bolt lift.

Yeah I think I'm going to back down a bit to try a lower node and see how that goes and use Superformance for the faster node. I also have the 109gr AH coming this week so I'll give StaBall a shot with those.
