I'm going to loan my .375/ .338 to a friend for a brown bear hunt and need some load data for 300 grain bullets. I'll probably use Swift A Frames. Thanks.

Loads developed for my .375-338 w/21" bbl. All loads with 300 gr NPT, RP cases and Fed 210 primers:

65.0 gr RL-15 V = 2,425 fps (this one can probably go to 66.0 gr)

66.0 gr IMR-4064 V = 2,495 fps

66.0 gr Varget V = 2,500 fps

Thanks. I'm using the same powders...good info.

Only have one load for the 375Chatfield/Taylor 300gr Nosler Part 66grs of RL15 giving right at 2500 in a 24" barrel.

Just google .375 Taylor. Tons of info on the round.
I can't pass on any of my data because i can't find my notes. I thought I had a couple of boxes loaded up but I gues I must have shot them up a while back.
