Interesting experience last week-end. Bought a Chiappa Mini-Sharps in 30-30. I wanted to shoot cast in it so I went through my once fired brass and picked out 50 FC and fifty WW. Resized them and then tried the Lee case length trimmer on them and only about one in ten touched the cutter at all and some were 100 thou short. What the heck , I will fire form them as is and then trim to a common length. I had some Speer 100gr. plinker bullets that I had picked up at a gun-show so decided to use them up to fire-form. Picked a mid power load of AA 2460 and loaded them up. First problem on bullet seating. My 30-30 dies could not adjust low enough to seat the short bullets. I have a set of 30 Herret dies so I tried the 30 Herret seater and we were good too go.
Ammo loaded --=-I take out the mini Sharps and it will only fire about every 5th or 6th round. The chamber is too deep so I will have to pull the bullets and set up a false shoulder with a 32 Special die and headspace off the shoulder instead of the rim.
O.K.-Just a minute I have a 30-30 Rem. 788 that I bought last year but have not fired yet. I test fire the loaded ammo in it and it shoots every time. I guess this ammo will be used in the 788 then.
I went to the range with a buddy to shoot off the fire forming loads. What a horror story that was. At fifty yards 4-5 inch groups. Used up the ammo and then went back to the bench and loaded up some 170 gr. lee cast hard and sized at .310 with a mid range powder charge of IMR 4759. At fifty yards it will put this load into a 1/2 inch group and stay under an inch at 100 yards.
Yup-this gun likes lead bullets. Now if I can just find a powder that is still being made that shoots as well.
