Hi
If you've tried this combination and have a good loading data please tell me about it? Not hgigh pressur loads which can send the bullet at 2000+ fps ,but low pressur and with rather slow burning powders.we had a long discussion before here but I don't dare 35 gr win 748 and 220 gr
regards
Danny

Do a search on this site Danny, this was discussed sometime back. - Dan

Loaded some for a bear hunter, a quite a few years ago, remember the powder(H450)not the load. It whacked back pretty hard, and the case was full.

35gr of 748 is good with a 150, but not a 220!

Try black powder or T7 with the 220 - also, use cast bullets!!
