A test of primers for my rifle.
Ruger #1 rifle 30-30 Winchester. 6x to 18x Burris
Richard Hoch 311173 single cavity plain base bullet mold.
The mold is dated 2-29-1984.
The bands are base .310 next .309, next .308. The bore riding part of the nose is .303 tapering to .300.
The bullets weigh 177 grains. Sized at .310, My own lube.
The barrel is a MATCO 5 groove chambered by M. Penrod with a .328 neck.
The ammunition was loaded at the range.
An Andula (sp) breech seating tool, Win 231 powder, R.P. cases, Harrell powder measure.
Primers tested with that same load are large rifle CCI 200, Rem 9 ½ M, Rem 9 ½, and large pistol Rem 2 1/2 primers.
I have other large pistol primers but no other large rifle primers
The group (6 shots) at 9:00 in picture 1 was 7.2 grains of Win 231 with the measure set at 79 clicks. This load was worked up using Win LR primers. I am out of those primers and can’ find any.
I then went to target 2 and shot the four 5 shot groups with the other primers.
I went back to target one and shot three more groups with the Rem 2/12 primers with a slightly heavier charge (79.2 clicks and 81.2 clicks.
The velocity for all rounds averaged 1237.9. This includes the large pistol primer loads. 32 FPS total spread for all shots.
