I recently bought a 375 Marlin and have gone through the first couple of $26 dollar boxes of power points. I found some Wisconsin Cartridge CO. ammo on gunbroker, and am waiting for their arrival. Are there any other factory outlets for the .375 WInchester out there. I've heard of Conley or Conely cartridge and that you had to buy 5 boxes per order. Once I get a good number of brass together and a die I'll start reloading for it, they seem to be at their best with 220-235 grainers. Anybody have any hunting experience with this one? If I can get in enough practice this summer I'll take it out for deer in the fall.

i use hornady 220 & 36.0gr rl7.. works fine in my contender carbine..

This is my favorite Hog hunting combo . The Hornady 220 gr bullet with aa 1680 can be loaded to 2350 Fps. this bullet expands well and holds together as well . With this caliber cast bullets seem to kill as well as jacketed bullets . reciently I have started to load My Baldy Bullets 300 gr LFN bullet. " actual weight is 290" . this bullet when seated to crimp in top lube groove loads and fires great . case capacity is the same as a 255 jacketed bullet and has a .338 Meplat .
I get 1650 Fps easy . Penetration is awsome . Only shot one Hog with it so far . For Deer the 220 Hornady is a 200 Yard load easy . A friend of mine in Missouri killed three deer at 200 to 230 Yds one season none went farther than 50 yards.
