Hy, My buddy just purchased a new Rem. in 300 win. mag. and want's me to reload for him. I have only loaded .243 win. , .308 win., and 300 ultra mag. My question is, what have you guy's found best for the .300 Win. mag.? I am sure he is going to go with a 180 gr. Accu-bond bullet. What do you guy's figure is the best powder's for it? Any info would be appreciated, thank's: Rick. P.S. Primer's etc.

I shoot 75.5 gr of RL-22 and 180 Accubonds. My rifle will shoot almost any 180's well with 75.5 gr of RL-22, but my rifle does shoot 200 gr Accubonds better.

Had good luck in mine with a max charge of H1000 under a 180 Partition.

Years ago when I had a 300wm, I used Re22 and H1000 the most. Another very good powder to try is IMR7828, now available in SSC.

Back then, Re25 and Retumbo were not available. I suppose I'd try those these days.

Push it with RL-22, H-4831, or IMR 7828. Great round.

MY favorite load is 83 grs. of R25 with 180 gr bullets. Work up to it. I'm getting ~3300 fps with a 26.5" barrel - this is a hot load! Great elk getter. Regards, AIU

RL22 has also been my go-to powder for the .300 Win Mag.

I like H-4831 but RL-22 is very popular also.

I was shooting IMR4831 with the 180 and got great velocity but pressure was high. I switched to H4831, lost about 100fps but a great, accurate load. I use 76.5 grains with the 180 Accubond and get 3130 fps from my A-Bolt with a 26" barrel.
