Load Development Help

[Stormin_67]

Been shooting some LR lately and decided to load my own ammo. I have some experience loading but am just a novice. My Problem I am having is trying to get the velocity out of my hand loads that I get w/ factory Hornady 140gr ELD match ammo My 6.5 CM factory load will chrono at 2750 with no cratering of the primer. I have tried H4350 and IMR 4451 and can't get close w/o cratering of the primer or a hole through the primer (see results below). I am using Lsoua brass w/ CCI 450 small magnum primers, 140 ELD bullet loaded .020 off the lands using a Hornady oal gauge. What am I doing wrong?? I'm using a 22" Hart barrel 1/8 RH twist.

Well, finally got around to testing the Hornady 140 ELD's w/ H4350 and IMR 4451.
At 40 gr
4451 .6" group
4350 1.3" group
No primer issues
Both velocities similar, upper 2500's

At 41 gr
4451 .6" group
4350 1.0" group
4451 no cratering and 2630 ish velocity
4350 cratering and 2660 ish velocity

41.5 gr
4451 .4" group
4350 .8" group
4451 some cratering 2680 ish velocity
4350 heavy cratering 1 blown primer 2690 ish velocity

42.0 gr
4451 .5" group
Blew 2/3 primers and 2690ish velocity

I would choose a different non mag primer to start then go from there. IMO

Do you have one you like? I normally use Federal but someone suggested the CCI small rifle magnum primer for the Lapua brass?
