Post what bullet you used with the picture
Here is one from my 130gr Speer HP with 18.5 grains of H110

I'm Shooting a 8.5" sbr and have a 100 yard zero that is a half inch low at 50 yards. I have not shot past 100 yards.

Curious on what y'all have set up?

Currently using RCBS measure, but it's sometimes off by over .5 grains on some charges. Some people say Lee makes a really good one, and some say they make the worst. Is there a good measure for stick powder even available? Even my loads for blackout with H110 are never that accurate. Any ideas othe...

Been hunting hogs with 300 blackout suppressed using a pulsar thermal for about a year now. Most of the time it's a friend of a friends place and we don't see crap. What's the best way to get on land with hogs?

Col is 2"
19 grains h110
110gr Lehigh defense controlled chaos

But same thing happens with store bought HP ammo. But never FMJ

I've tried many different types magazines too, even the 300blk Magpul and lancer mags.

I've tried both Magpul and lancer magazines for 300 BLK. I think it's a feed ramp problem, maybe the corner of the HP is catching a groove?

I was hoping someone here had this issue and a solution. *Cross fingers*

8.5 inch Balliatic advantage barrel, fail zero nib BCG. Seekins upper and lower/ parts. I shoot Suppressed. Anyone seem this issue before? FMJ cycle fine. Tried different BCG and lots different magazines. Same result, happens like every 3 or 4th shot.
