This down load testing was to near duplicate or reduce factory energy levels of the 30-30; thinking of the performance of the 6.5 Carcano.
The cases were made from .243 Winchester brass,primers were WLR, bullet was the sp bt 139grain PRVI, OAL=2.950". 20 to 35 mph wind all day. All powder seemed to burn.

42.2 grains H4831, mild but sooty , 2316 to 2359 fps. fair accuracy.

32 grains XMR4064, mild some soot, 2144 to 2191 fps. deadly out to 200 yds.

31 grains H4895, mild some soot, 2156 to 2178 fps. 5 shot 1.000" group at 50 yds.

31 grains IMR 4895, mild some soot. 2148 to 2213 fps 5 shot 1.000" group at 50 yds.
It would appear that this down loading went well. roger

Old age is a high price to pay for maturity!!! Some never pay and some pay and never reap the reward. Wisdom comes with age! Sometimes age comes alone..
