But I load for both too. Our 14” (I think) .30 GNR typically runs 2200-2400 with 150 gr. jacketed bullets. I think I was using 4895 and I always work up my own loads, seating the bullets just off the lands with the action closed. I took a Blackbuck at the Y-O using a 14+2” braked .338 GNR and 200 gr. Nosler bullets. Basically a completely full but not compressed load of BLC-2. IMR3031 is a good powder too, 4064 is a little more bulky and not as fast, maybe 5% less, but really consistent.
Don’t get too hung up on speed. A custom requires some fiddling. That’s the fun part. The data and custom set ups are not cut and dried, cases, powder lots, primers, brass, seating depth, all sorts of variables. If it’s accurate and pushing over 2k that’s good. My .30-30 Contender loads were topped out about 1800/150 gr.

Your 36 gr of H4895 is LOW, mine takes 39 before I get

- 30 GNR -- O.A.L is 2.950" with a 150gr Nosler (nm) - Sean Harper, 2025-08-11, 10:54
- By seating the bullet longer it increases capacity - WB, 2025-08-11, 09:43

Normally I would agree that accuracy over velocity
