I have been shooting and hunting with the 300 H&H since the early 1950s...Still shoot the same load and that is a cup full of old surplus 4831 which I have a gob of, but you can't do that with todays 4831, so go with a max load of H4831 in your 300 H&H ...I shoot it with the 180ge. 200 gr. and 220 gr. Noslers...

For the last 30 years I have shot the 200 gr. Nosler almost exclusively with an ocassional go with the 220 gr. at 2700 FPS....Havn't used the 180s in number of years because the 200 are so much better..I regulated the 180s to my 06.....

I also like the Woodleigh 220 gr. bullets a lot..I have a client thats getting old and has some stiff joints so I load him up some Woodleigh solids and softs in 220 gr. weight and he has shot Lion, Cape Buffalo, Alaskan Bear and elephant with 100% success with his old Rem 721...

H 4831, IMR 4831 and 4350 are my powders of choice with a definate preference for 4831...
