I recently acquired an Interarms Mark X in 458 Win mag. I bought it on a whim and want to do some shooting with it to decide if I want to keep it or my 416 Rigby Ruger Safari Magnum as my big bore rifle. I've been looking at reloading data and can't find any for RL=15 with 400-500 Grain bullets. I found data for similar burn rate powders but none for RL-15. According to the burn rate chart in my Hodgdon manual RL-15 is slightly faster than Varget for which Hodgdon shows data so I'm thinking RL-15 should work. Alliant doesn't show any RL-15 data on their website. I have a good supply of RL-15 but no Varget. Does anyone use RL-15 in their 458 Win. or have access to any data they can share? Thanks, Tom Z NRA Life Member | ||

Woodleigh loading Manual starting loads for .458 Win Mag with 500 grain bullet is 68 grains of RL-15 | |||

I reckon it will be too slow for top loads with 400 grain bullets and with 500 grain bullets all the powder you get under the bullet will probaby see 2000 f/s plus. I foud you can use more Re 15 in a 375 than Varget or 4064. | |||

Thanks RIP. That's just what I needed. I'm only going to be punching holes in paper for these initial loads to check out my new toy. Tom Z NRA Life Member | |||

Re7 was great. I seem to remember that when used in a 222 as compared to 4198 it was fater burning then when both were used in a 458. | |||
