That's real close to the same as my saum then. 3500 is my max speed that doesn't leave an ejector mark so far. I'm gonna try for 3600 today by jumping the bullet. Have you tried superformance yet.

OK! Thanks for your input!

The first revision to the loading data table is now posted. The original table has been updated and is in the same place.
YOU'RE GONNA WANT TO LOOK AT THIS! Shep has blown past 3500 fps with his 6.5 saum and shot groups in the 1's!
Be very careful trying to emulate what he is doing. He is a Very accomplished benchrest shooter and gunsmith. Jamming these new bullets could seriously increase pressures. I'm not fully sure how he even accomplished it!
Be careful and sensible out there......
Link??

When I did the rl23 test it was jumping .020. My h100v test was done with .002 jam. Gonna jump the h100v today to see if it will do the 3575 without pressure. How much are you guys jumping the hammers. Where is the jump sweet spot.

That's a bunch but I can try it. Although my .002 jam is shooting one oval hole for accuracy. Really I could just stop now. 3500 fps with one hole accuacy what's not to like.
But heck if it will do 3600 and stay under 1/2 that will do also. But I'm kind of an accuracy snob so the 3500 might have to do.

I really need to pull my barrel and throat it out another .050 with my bore rider reamer. I know it will do over 3600 like that. The bore rider throats are good for 100fps easy in everything I've tried it on.
