OK so I went to the range and played with 2 loads that performed the best.
I was using a Monarch 3 1-4x20 w/German #4 reticle. Probably going to switch to a scope with a more varied magnification (2-8, 2.5-10, or 3-9).
Rifle Rem 700. Sierra's 225gr Spitzer. Chronograph was 4ft from muzzle. Target distance 100yds
Load 1
51gr's of IMR 3031. CCI 200's. Remington case
Avg 10 shot vel 2460. High 2481. Low 2441. Dev 40fps
10 shot grouping was 2"
Load 2
55gr's IMR 4895 , CCI 200's. Rem cases
Avg 10 shot vel 2451. High 2472. Low 2430 Dev 42fps
10 shot grouping was 1.75"
Just for the heck of it I tried 5 rounds of each load at 200yds. Now with the scope I currently have on it parallax will be an issue and I had to pick a point where I thought the middle of the target was. Top magnification just didn't quite outline the target centre lines.
Anyway Load 1 grouped at 3.10" Granted there was a bit of a crosswind which didn't help.
Load 2 2.75"
Not bad. Probably could do better with a different scope.
