I think we have success! My first five shots was with a 230 gr bullet, paper patched over 18 gr of reloader 7.

The second five shots was a 200 gr bullet paper patched over 18 gr of reloader 7.

Both five shot groups at the same target at fifty yards.

Glen you 100% right , I form my brass from the 38-55 long and trim back to 2.125 that gets me .005 off the chamber wall and with cast loads seems the brass doesn't grow after that.

That looks like your typical 30-30 chamber - no throat. A .310" x 3° throating reamer will do wonders. Careful measurement may also show that the chamber is considerably longer than your cases. Reforming 38-55 brass helps with that.

Yea , I also heard that if I just put some valve grinding compound on a bullet, tap the end with threads install a bolt and use a cordless drill that I could increase the throat, But I think I will try a throater first and see how that works.

In my Savage model 340 and with the reliable Winchester model 94 I have good groups with bullet up to 200 gr. but with the COL length limit and the 1/12 twist that seems to be my wall. With the Contender I'll have no limit on COL and the 1/10 twist should do well with the heavies.
