We all know that with heavies, RL 17 can't be beat. We all know that RL 17 punches WAY out of it's burn rate. Probably the versatility king, of any powder. I've shown yall what the 9.3x62 does with 2000 MR as well.
Gunner 500, that beretz guy, then the CZ 550.ca feller has already shown yall what the mighty 9.3x62 will do with 300-325 grainers & RL 17.
Can this newer N555 powder punch out of its burn rate?
Last night, worked up to 63 grains under a 325 grain oryx. No excessive pressure signs. Was too dark for the chronograph.
Just loaded to the absolute fkn max: 64 grains. Heavily compressed, heavily crimped, magnum primer, bullet loaded out to "max-mauser-COAL".
Wait one and I'll report what the chronograph reads.......
