With Big Game it's 82.5 gr for 2931 fps.
With Rl15 it's 76 gr for 2883 fps
with H380 it's 81 gr. for 2854 fps
Saami max OAL is 3.340"

Big Game worked better than RL 15 in my gun but my one friend developed a great load with RL 15 and the 260 gr AB the other friend used it also with the 260 gr Partition both had their best accuracy at 74 gr. All 3 guns are tackdrivers, in fact some varmint guns would be jealous with how well they shoot

I have been having a hard time seating the 260 AB. Folds the cases when trying to seat the bullet to the cannelure. Is that to deep maybe? Putting heavy chambfer on cases, lubing bullets, adjusted dies over and over. Tried other bullets problem still present just not as bad. Called Hornaday a number of times and still. Cases folded! Any ideas or suggestions would help. Thx.

Hornady cases are pretty soft in the neck area. I have have the same issue with Partitions which have flat base until I switched to Win (W-W) cases. Welcome to the forum.

Welcome to the forum. It is frustrating when your cases are bulged or creased. It sounds, however, as if your seating die is adjusted too close; consequently, you are pushing the neck back. Try raising the ram, with a sized cartridge in the shell holder. Screw the seating die until it just touches the shoulder of the sized case. Now, back the seating die out at least one full turn, and lock it in place. This should permit me to seat your bullets without depending on the die body. Use the seating stem to adjust the seating depth. This should allow you to be good to go. Do not lube the bullet; that is unnecessary and may cause contamination problems.
