I did some below zero velocity testing with my 200.20x Berger load. Factory tikka 24” barrel. Zeroed for Norma 180 Bondstrike.

H4350 with the 200.20x had a 7 fps velocity increase going from between 57-59 degrees in July (average of 3 range sessions) to -7 degrees. The change per degree is small enough across that temp range to call it zero change.

H4350 with 200.20x works well for me.

What is your charge weight with the 200.20x? I've got an 8# of H4350, Norma and ADG brass, and 500 bullets to play with. Hoping to get a good load to try in the 300WSM barrel I have. Hopefully the 11 twist is fast enough for the elevation I hunt in.

You should be in the ballpark between 61-62 grains. Start low and work up. I don’t have my notes handy, and I ended up sticking with the 190 LRAB to have commonality with my hunting partner. We run the exact same load.
