Comparing loads in the Nosler #6 for the .300 Win. it lists 70 grs. of IMR-4350 @ 3130 fps. with their 180 gr. bullets. If H-4350 was substituted and worked up to this velocity would it be safe ? Also, has anybody acheived this velocity with these powders ? I normally load H-4831, H-1000, or RL-22. I have never tried a faster powder in the .300 with 180's.
Thanks,
Jim
