375 In An AR15 Platform

[44caliberkid]

What is your favorite .375 cartridge that works in an AR15 size receiver and why? I am aware of the 375 SOCOM, 375 Raptor and 375 Stalker. I'm not interested in sub sonic loads, so maximum performance would be my goal. I already have and load for 458 SOCOM.

Since you've got the large caliber covered, I'd suggest a 300 HAM'R.

I too already have the 458 socom and was interested in the 375 socom. It's ballistics numbers were not enough different from the 458's to get me to follow through. There's a guy who makes all kinds of medium/big bore wildcats for the AR 15 (usually with names that sound like "rabid sabertooth killer tigers on the loose") but they are often black-belt brass-forming exercises. Tromix also makes a 358 socom. The socom case is a proven one and is a top performer in reliability in the AR 15 IMO.
