After a little bit of a learning curve I have found a load for my .356 Win.
This rifle has a bit of a generous throat and chamber. It also had a tight spot in the bore under the rear sight, which I was able to remove by firelapping (my first go at that and was pretty nervous).
I have a RCBS -35-200-FN that cast dead on .358 with COWW+2%. I sent it to Erik at Hollowpoint Mold Service and had it opened up to cast at .361.
So to make a long story short. Sized to .360, lubed with Carnuba Blue and seating as far out as possible to cycle every time in the lever-gun.
Ladder tested with IMR-3031 starting at 38.5gr and went up the 41.5. Found a accurate and repeatable load at 40gr.
I have to say I was pretty excited. Very close ES and SD and good groups. My shooting area at my home only allows for 85 yards but I think the load is dialed in.
Sure is fun when it comes together.
