Okay Service Conditions shooters on a budget:
I'm shooting a Hornady 68 gr HPBT exiting at 3000 fps using WC735 surplus powder from Higginson's shop. About 25.0 gr will get this velocity. This is a warmish to hot load!
What barrel length and twist rate are you using?
I just got back from a range test of the:
Hornady 68 gr FMJ HP BT
using 24.0 gr of H335
and found it to have a 2823 ft/s muzzle velocity (+/- 43 ft/s)
through a 16" barrel with a 1:9 twist.
It would appear 6 out of 10 shots would be within a MOA, 2 out of 10 shots would be within two MOA, and 2 out of 10 shots would be within 4 MOA
In other words, I had about one "flyer" for every 5 shots taken -- the sample size being 49 rounds.
I do not remember having such an issue with:
Hornady 2267B 55 gr FMJBT
using 23.8 gr of WC735
and found to have an average muzzle velocity of 2876 ft/s
Currently, it looks like I am better off using the 55 gr FMJBT for the upcoming Service Rifle match...
Or do I need to push the bullet faster?
