Hornady 68gr issues #1

Posted 10-16-2012 at 11:58 PM by mroels

Frustrating morning at the range. Previously favor loads are being beat out by previous crap loads. A new bullet that has previously performed well was all over the place. Any input appreciated!

Pre-range: Rifles got a thorough cleaning this week. But before testing loads I fired 10 fouling shots through each of the rifles.

Shooting: Considering recent cleaning I tested round robin style, 2 minutes timed between each shot for consistent barrel cooling. Timed cease-fires for the same reason. I was probably a big part of crappy groups, was a little tense for whatever reason, but definitely not for the extreme crazy big groups in .223

Mistake: My lowest loads were messed up because I took the fouling shots at the 500yd gong and forgot to bring scopes back to zero, so 4 shot groups instead of 5. Made this mistake twice.

68gr Hornady HPBT Match
RAM TAC 22.5, 22.7, 23, 23.5, 23.7, 24
CCI 41
Black Hills Brass
2.255" OAL

Rifle: AR15 RRA 16" 1/9
This was just a failure all the way around. Nothing under 1.5MOA!! I just switched back to this bullet after using Nosler 69gr. In the past I was getting solid .75MOA if not better. I chose to go back to this round due to high BC. Only thing that I changed since the past was OAL, I went from 2.20" to 2.255" so I'll have to retry this. Also my brass is on it's 5th reloading, could this be causing these terrible groups?

ETA: Measured and weighed bullets. Grains went from 68gr to 66.7gr. Length from 0.9905" to 0.9845". Diameter from .2225" to .2235", none at .224"? Is this variance normal?

Well at least I got to shoot today!
