Today was the first time out this year as expected some rust to shake off. Besides the H4350 Creed test and the Sub 308 , I tried out a new scope I mounted on the 375 Wby this winter. I had sent the scope I had mount on it back to Crimson Trace. I took a generic load of 270gr Speers and Hybrid...
Back around the first of the year I toyed around with the Hornady 220gr RN and TiteGroup for subsonic loads. Not that I could finally have time to hit my range , I tried them out.
My S2 Vanguard has a 1:12 twist and I found that to be a handicap. They impacted 18.5” low on my 208gr A-max zero...
Digging this up again. Today I had a chance to run H4350 in this test. The only difference today is I’m using my Garmin and the Striker has a different brake that won’t allow the Magentospeed to mount.
44grs is all one can load in this case.
5 mph wind should show less than 1/2” at 100yds.
A bi-pod that’s not being preloaded on a slippery surface is not ideal for load development.
Anytime a variable is introduced into a load , I start from scratch.
2 years ago I picked up some CCI 250s and they were a pain when used in my 338WM.
The 90gr AH have been little stinkers it 2 of our 257 Wbys. This summer I might try H4350 and see what I get.
The 124gr HH and 404gr SH soot great for me.
