Any 300BLK 110 GMX loads?

[roggom]

Looked at published data, but most 110 for 300blk are using varmint bullets. Im trying to replicate the Hornady custom load. They have a 110 GMX going 2285 from the muzzle, seated 2.210. Im using a 16" CMMG Resolute upper, suppressed.

Looking to drop some muleys. I already have 30-06, 308, 7x57, 260, 7mmmag under my belt. wanna try the 300blk this year, well at least for one tag.

I have Enforcer, imr 4227, 2400, & lil gun

Have you checked 300blktalk.com?

Thanks for the tip, I just checked and nothing posted. I only ask because CO has a min ft/lbs requirment. I could always shoot the factory (meets 100ft/lbs at 100Y), but I have 100 110GMX and would like to roll some. I dont want to burn through 30 or 40 looking for a node as those suckers are expensive.

Hornady Book lists the 110 GMX @ 2.210“ with the same loads as the 110 VMax @ 2.050”.

I have an older Hornady book does not have the GMX listed for 300 blk. . Excellent. Thanks

 

[Spblademaker]

No. The newer one does. looks like lil gun is your best chance at speed, vs 4227, according to the book With H110 being even faster. I only use 4227 for my 110 loads. Good luck.

Reached 2400 fps with 20.0 grains of H-110 gave minor brass mark with no primer issues. 2.22" OAL as the LE round is listed at. The book shows 2.21" OAL max. Accuracy nothing to write home about, I'm accuracy testing back down the ladder a half grain next. Suggestion for Mods: I think the blackout is getting fairly popular these days. Please consider making the" 300 BLK Load Data thread" a sticky? It is old, but we are posting/getting more interest in the caliber.

Thanks for the info, Ill pick some H-110 up, been doing a lot of reloading during these times. Cant wait for the snow to stop(muddy fields) so I can get out and try some loads.
