The 22 creedmoor thread

[Matt5266]

I agree with others, keep going. My 18 inch .223 with that bullet is pushing almost that same speed at 2765 fps

Loaded up 5 rounds of 77TMK at 2.56” COAL with 40.0 gr of H4831SC and the group shrunk drastically. Average speed was only 2786 with no signs of pressure.

Should I bump my charge weights and see where that puts me or just load up 10 more of these and roll with it if it the groups stay tight? For now this gun will only be a 500 yard and in gun.

What say you guys?

What barrel length?

What barrel length?

16.5”

I’m going to keep pushing. I did a little more digging in this thread and it looks like there’s a handful of guys that are running at 42 grains of H4831 with this setup. I’ve always been overly cautious about loading too hot. But it seems like I have a lot of room to work.

I thought this was the 223 thread for a moment. I shoot the 77 TMK or 80 ELD-M at 2800 from an 18” 223 with 26.0 of N150 with no pressure signs.

You should be around 3100 with those from your 22CM, even from the 16.5” barrel.

I have two 16.5’s, the 77gr TMK load I just settled on is just shy of 3100fps with 42.7gr N555. I got very very light extractor marks at 43.0. I was hoping to use Varget but was was getting those light extractor marks around 3050 FPS with 35.7gr and poor case fill.

Ive shot several deer with both the 80 Eldx and Eldm now (3250 fps). Am preferring the Eldm at all ranges. The Eldx can pencil for no apparent reason. The Eldm always penetrates and expands.

Thanks for the feedback. Typically, I would go with the M's as well, but in this barrel, the X's shot just a little bit better than the M's. If I'm not satisfied with the terminal performance, I'll load the M's.
