Took out the 22-250 AI tonight, it shot 0.7 edge to edge on a 4 shot group with winchester 45 grn jhp value pack....... Not bad for a case forming mission. Th fifth round I didn't measure into the group as it was the first shot at the range and was an inch off.
My .257 wby weighed in with a 0.60 edge to edge group for a 0.44" group center to center, not bad for a stock Wby Vanguard with a Bushnell Banner 3-9X40. Load was a 117 BTSP Hornady over 77 grns of WC 868 and a Fed 215. Case: Nosler Custom 7mm rem mag reworked to 257 wby and necks turned to 0.0105" neck wall thickness.
I actually never intended to use this load for anything more than forming the cases, but it shoots like a match load. Funny, this rifle generally shoots that way. It will be the deer rifle again this year, no question, I am confident in my shots with it.
The new 22-250AI isn't much different, but I know it will not down a deer with the authority of the 257. I can't wait for my dies to come in. This rifle shoots great with
junk that used to be something I only used if I had too. I do, however have 22-250 dies and a hundred cases or so to make form loads with. I bought some Sierra gameking 55 grn BTHP's to form with. $21/100 in Canada is pretty cheap with the insane prices that stuff goes for now. I have no intention of wasting my preciously small supply of 50 grn NBT's on forming :twisted: those are for the go FAST loads......
My 375 ICL came out tonight and I tried her with full power improved loads instead of just factory 375H&H loads. 84.5grns of W760 under a 300 grain Nosler Partition. QL suggests 2750FPS with this load and once again expecting to get rained out, I never brought the chrony. It shot about 2" and I had to adjust my zero up about 8" from the 270 grain fedral loads I bought. It hit exactly where I aimed it on the last shot, but recoil is pretty stout even with a 12.5 lbs rifle. I beleive that the load was alot better than I shot, I will test it properly next time with a lead sled. No sense in getting abused by it off the bench. I will also install sling studs on it, likely two fore and one aft. I hate to admit it, but I'm becoming very dependent on a good secure shooting platform.
It's 1130 and I'll post pics later.
G'night and great shooting everybody.

Prayers and sympathy for the people at the Big Valley Jamboree in Camrose, Alberta tonight that were involved with the tornado that tore down the main stage, killing one person, sending 4 to the hospital in critcal condition and injuring 60 others.
