Ok, I felt up to getting out shooting a bit tonight. Near perfect evening at the range. Wind was great for South Dakota ranging from 10mph to near zero in my face.
When I set out to test H335 under the 87 gr Absolute Hunter I found my remaining stock was lower than I recalled. So I only loaded 4 rounds to compare to the individual in the video.
My barrel is the 22" Pacnor in the CZ 527 bolt action. Working with Starline 6.5 Grendel reformed to 6mm ARC 3 X fired.
Primers were Rem 7.5, OAL was 2.250"
Velocity results were as follows measured with Magnitospeed.
29 gr yeild was 2983
30 gr yeild was 3099
31 gr yeild was 3205 primer flow around firing pin was significant
31.6 gr yeild was 3251 stiffness was realized with bolt lift
For comparison 3 rounds of last falls IMR 8208 loads were fired for velocity comparison.
29 gr of IMR 8208 XBR velocity yeild was 3068
3048
3033
