Thread: 52g ELDM in .222

Just wondering who's running these in their trebly and what powder they're using. I've got 2207, 2219 and BM2 on hand. Hoping to cut down on the faffing about and go with something proven. Thinking 2219 to start with.

Any advice welcomed.

What rifle?

I’m running 50 gr vmaxs in a sako.222 but also played with some 52 gr HP Speers

Pretty sure I’m using BM2 powder but I’ll check when I get back home

Tikka M595

I'm using 2207 with 52gn Speer HPs and 50gn Winchester PSP. Shot well enough haven't tried other powders. Bergara single shot 20" barrel.

Win 748 for me.

I’m using BM2 with 60gr Hornady in my .222. Very accurate.

Win 748 and 52 Sierra's work for me.

Win 748 & 52gn Targex

Go the BM2, it runs really well in the 222 with a near full case.

well so far on ones has mentioned eld-m's, so looks like we are not really of much help! Have you worked out seating depth/COAL yet? Or restricted by magazine length? If you tell me your COAL I can punch some numbers in GRT and see what that says for the 3 powders you have to hand.

Haha correct but that's no bother on this occasion. Definately not restricted by magazine length. Was just going to start with OAL from the Hornady manual which is 2.180. Or do you need CBTO?

that'll do, what barrel length?

570mm, case capacity is 25.3g H2O

That's a relatively low case volume. GRT is showing following max. loads:

2207 18.7gn 3080fps, 95% burn, 95% case capacity
2219 21.5gn 3110fps, 92% burn, 102% case capacity
BM2 21.6gn 3050fps, 83% burn, 98% case capacity

pointing towards the 2219 I would say from that. In theory if the burn load is too low it can lead to velocity variations. Don't just trust GRT though, see what reloading data on reputable websites say for max loads, then compare actual velocity to what GRT says. Its pretty close for my load in my single shot 222, which is slightly over ADI book max.

based on 55,000psi max pressure.
