6.5x284 120 GMX

[TysonLeal]

Been doing some load Dev for California for my 6.5x284 Savage LRH. Having used the GMX bullets in my 270 win I liked their performance and wanted to try them out in my LRH.

I figured out the Berger 140's, but the GMX 120's are a slightly different animal.

My current load that's getting 1MOA is:
54 H4831sc
.05 off/3.174 COAL
CCI primers
Nosler/Lapua brass

Anyone have something out there for this bullet that has performed well?

TL,
Don't have anytime behind the GMX but I have had great accuracy with the 120gn Ballistic Tip (I know it's a totally different beast), RL25 and CCI BR2's.
I tried 58.0, 58.5 and 59.0gns and my OAL from base to ogive was 2.5490". 58.0 provided the best ES and SD numbers (28.29 and 15.62) which weren't really great and accuracy was .586". 58.5gn gave the best accuracy @ .3445" velocity was 3225fps. 59.0 was .380" @ 3267fps but I went with 58.5gns.
This load (58.5gn) shot 1.5 - 1.75" grolups @ 500yds, several times.
They shoot great but I left them for the 140gn AMax's and now, ELD-M's. I am hoping that the 143gn ELD-X will shoot as flat and fast as the ELD-M does. Now if I can just get some!
Happy shooting/hunting. Be safe, live long. JohnnyK.

I have not tried the 120 gmax but there are 2 unverified loads on reloaders nest. H100 shows promise in my cooper 6.5x284.

Unverified load 9045 in caliber 6.5-284 Norma

Good luck and shoot straight
