Without curiosity, evolution would have been greatly flawed.....
just watched your video. when i first saw your 25.1gn group i thought there was parallax issues. after watching your video i think there is some pilot error getting in there as well.
not picking holes or anything else, just a couple of thoughts. your head is bobbing about a lot, almost as if your trying to get a good cheek weld on the stock. also seams there is some snatching at the trigger.
try shooting the group without taking your cheek weld off the stock, even when reloading.
a 223 with a good barrel is not over fussy so should be giving better results. i shoot 40sbk. 40vmax and 52amax. all have a massive node of 1.5gn, with the n135 and i have to seat them according to the bullet length and not COL.
as said, not picking, just commenting
I would be peed off if that was my dry stone wall.
Yeah you're completely right. The size of the group there was more of a reflection of my shooting ability as apose to the load. Certainly cheek weld is an area that needs improvement. Also, the dot I was aiming at wasn't particularly precise with such a fine reticule.
I'm happy with the load all the same

Dude, lower you scope as almost zero cheek weld.

Have you tried vit 140, I use it in .223 and get very tight groups, it also meters very well

For what its worth my best 5 shot group at 50 metres was 0.22 inches that was using 24.0 gn of vit140 behind a 69 gn sierra match king.
I have had similar results with cfe 223 same load and head.
Like Varget Vit 140 is an excellent powder in mid size cases with similar capacities to 308, it has its uses in smaller capacity cases where the bullet weight is approaching the upper limit for the cartridge but there are better suited burning rate powders for the 223, Vit 133 being one of the best.
