I have a few loads with 23 saving it for the main hunting gun everything else I’ve lost hope on finding more and switched powders

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.

I’ve been having a terrible time getting copper bullets(190LRX and 190CX) to shoot so going back to lead. My load of 66gn H4831SC under a 215 Berger at 3.290 COAL(throated +0.100) shoots mostly 1 hole and 3/4 inch overall so I have a pretty good thing going. The 212 ELDX didn’t shoot as well for me so not going to bother. I also have some 200gn accubonds I am going to try.

Assuming the Berger and accubond are equally accurate which would you hunt with? I only like to shoot out to 500 yards but may push it if it seems like I need to. Expected shots are usually 200-500.

Berger 215 at 2720
Accubond 200 at ~2870(assumed velocity)

I've shot and used both. Berger 185s and 180 accubonds out of my 300wsm. 2 completely different bullets. Both will work well. The bergers definitely gave me more meat damage though.
