300BLK C.O.A.L Recommendations

[Bluenose75]

Hi, I have just loaded some Hornady 300BLK brass with Sierra TGK Game King Tipped 125gr for load testing using N110, I found some load data from Sierra for TMK heads which are very similar and the COAL is 2.250 they look long, any recommendations, perhaps seat them on a little more? Will be fired form Ruger Ranch 16” barrel.
Thanks in advance.

I use either Nosler 190 Custom Competition or Lapua Scenar 167's in my Ruger, COAL for both is 2.25"

The TGK will chamber no problem at all.

If you're looking for grouping at 100yds run a ladder test, my Ruger prefers heavier bullets.
My load for supersonic is 16.4gr of N120 under the Nosler 190's, that gives me a 1" group at 100yds.

For indoor subsonics I'm using 3.8gr of N310 under a Shell House Bullets 175gr coated BTHP, again heavier work better,
their 200gr round nose feed OK but they are now expensive as they won't supply them without gas checks and lube as they used to.

If you're wanting to shoot subsonics the Ruger doesn't feed flat nosed bullets, even with the improved Magpul PMAG 10 round 5.56 .223 AC AICS
magazine and an AICs compatinble chassis it jams on almost every round.

Thanks mate. These are for supersonic long range fun, was just worried I was to long, didn’t want any drama on my ladder test think I stared at 14 and up to 15.2
