So once again, RL 17 is giving velocities way above anything else.

exbiologist great info! I would have thought 4007ssc would have been at the top of the list....

4007 had one of the highest velocities of any published load that I used. Hodgdon publishes something like 61.7 gr at 2770. I fell short of that, but had much better luck with extrapolated loads for 200 gr bullets in the 300 WSM.
I thnk the only other "book" load was 67 gr of RL 22 in Lyman 49 at 2790 and I was a little short of that too. Johan at Accurate/Ramshot told me MagPro and 3100 were too slow to use, I didn't think much of his advice and used it anyway.
Now these were just the max loads that I tried, doesn't mean they are truly max. None of these had ejector marks, I resized all of those and there was no problems seating new primers. So if you're feeling up to exploring the real limits, go for it, but these are pretty safe maximums. Just hoping that the RL 17 load is accurate.

thanks for posting and doing all the foot work on them big 220gr bullets! My way of thinken is a 220gr AFrame @ 2850fps would get the job done on anything in North America and most of Africa BG!!!!
