Here is the first shooting I did with it. No break in. About 5 shots to get it on paper and then I started dialing it in.
Posting the whole target lest I get charged with "cherry picking".
Remington 221 FB Brass, FL sized to 20VT, Remington 7 1/2 Primers.
Large Target - 5 shots to sight in using 32gr V-Max and 18.4gr of H4198 (.758 - .204 = .554)
Top Left - 5 shots 32gr V-Max and 18.0gr of H4198 (.715 - .204 = .511)
Left Middle - 5 shots 32gr V-Max and 18.2gr of H4198 (.526 - .204 = .322)
(For some reason, it looks like only 3 shots hit the paper. Can't explain that one.)
Bottom Left Corner - 5 shots 32gr V-Max and 18.4gr of H4198 (.505 - .204 = .301)
Bottom Center - 5 shots 32gr V-Max and 18.6gr of H4198 (.804 - .204 = .600)
Bottom Right - 5 shots 32gr V-Max and 18.8gr of H4198 (.931 - .204 = .727)
I know they're different loads and I would think that puts me at an disadvantage, but this is all for fun so I'll take my chances.
Average group size = .503
This was shot off a bench at Bristol Range in Bristol, WI. I use a Protector rear bag and a CaldWell Rock front rest. Shot within an hour or so on the same day. 100 Yards distance.
Note: These are MY loads in MY gun so please, don't duplicate them.
I haven't chrono'ed them so I don't know where they're cooking at. I can tell you that I hit multiple PDs are 400 yards on our recent trip. All in all, on of my favorite rifles.
Thanks dmpowder!!
