Hi darkwing,
I first used WLR then switched to Rem 9 1/2 primers I use Winchester cases exclusively as the bolt face has been machined to match the Wnchester case head which is undersize. Now I am reluctant to post teh actual grains used because I started using this load after reading an article in Petersen's Rifle shooter. Soup up the 30-30. My rifle is a custome bolt action and th action would normally have be made into a .308, .243 or some othr modern high pressure round so actions strength in not a problem. Also being a bolt action with stahggered box magazine I use spitzer or pointed bullets. Velocities are around 2800 fps for the 130 grain Hornady Spire Point and 2750 fps for the Sierra 150 Grn Flat point bullet.
The person who ordered the rifle built specified Winchester 170 grain factory ammo and the rifle was built around it right down to the magazine length so I cannot use 150 grain spitzers as they require seating too deeply in the case. Any bullets over 135 grain in weight need to be of flat point or round nose configuration but as yet I have not achieved good accuracy with the 150 grain round nosed bulltes. This is how it shoots using the 130 grain bullets and H-335 powder :-
The group is 3 shots taken froma rest at 100 yards.
This is a sight in target when I was setting up the scope and rifle for this load. The top group is the first three fired I then over adjusted and took the fourth shot which went too low. the final two shots were about right and I had only loaded a few rounds.
The rifle has a 6x42 scope fitted.
