22-250 load data to share

Hey guys, I've just put together a 7twist 22-250 on a 700 action. It is a 24" criterion remage barrel. And, I wanted to share some load data with everyone. Remember to load down and work up, as to chamber differences, so everything will be safe.
I worked exclusively with the 88gr eldm in lapua brass, with 3 different powders, all of which produces sub 1/2 moa groups.

H4350, h4831sc, h1000

H4350 produced the most speed @ 2956fps with my accuracy load. Started @ 33gr and worked to 35.5gr where I began to see an ejector mark. 34gr was my accuracy load.

H4831sc, to me, is the most accurate @ 2932fps with my accuracy load. Started @ 34.5gr and worked to 37.5gr where I began to see an ejector mark. 36.5gr was my accuracy load.

H1000 gave me the smallest sd of 4.1 and 2904fps with my accuracy load. Started @ 36.5gr and worked to 38gr, just began to crunch powder and hardly any room left. Luckily, 38gr was my accuracy load.
 
34gr h4350 is the group that has 44gr written on it. 44gr is a typo.

while working with 4831sc I found a very accurate load @ near 223 velocity. 35.5gr gave me 2833fps with outstanding accuracy. Thought this would be interesting if someone wanted more barrel life.
 
I stepped down to the 69 TMK for a bit more velocity. It's a 24" pencil barrel ruger stainless 8 twist. I use AR Comp and 32 gr netted 3200fps, and it shoots under an inch every time I take her to the range. Can't complain a bit about it, connects on the gong solidly. Gun is a walking 7 lbs scoped rifle.
 
We have two .22-.250's with 7.7 twist barrels and shoot Hornady 68 hpbt & 75 ELD's with either H4350, H414, or Re16. Loads are 34.5 to 36.0, depending. A 3rd 7.7 .22-.250 is in the works.
Velocities with the 75 ELD run close to 3300.

36.5gr 4831sc for 6 shots

I am always looking for universal multi rifle powders like for 6mm AI, 6.5-06, .280, 6mm Rem - it looks like I will work on H4831SC with the 75 ELD's. IMR 4831, cheap and abundant at LGS, is another possibility. Sierra has 36.6 grains of IMR4831 @ 3050 as their .22-.250 accuracy load with their 80 MK.

I like to see bullet holes in felt tip marked paper plates. The .22-.250, with pointy 75 plus grain bullets, is potent.
