Any thoughts on full length versus neck sizing on the .375 RUM? The rifle is an HS Precision, and will go to Africa again next spring. I am just about to begin reloading for it, having used factory ammo with 300 gr A-frames. It shoots well with these (about 2 inches at 200 yards) but I'd like to try some 300 gr Barnes-X. Might one encounter chambering issues on a dangerous game rifle with neck sizing only? By the way, the factory load on my chrono comes in at 2865 fps.

Marty,

I have tried the neck sizing, even bought the die, but it didn't make any difference that I could see. I'm full sizing again and using 270gr Barnes XLCs and Vhitivouri N160 experimenting, more or less w/Saeed's .375/.404 loads listed on the reloading pages. Accuracy is amazing and very easy to shoot.

My opinion is always full length resize. Not only might you prevent a jam, but it's more accurate. High power target shooters who win at Camnp Perry full length resize every round.

Marty,
Ovis and Indy are steering you straight. I even full length resize for my 6mm PPC. More consistent (for me any way).
Never neck size hunting ammo.
