Use IMR 4320 for 260 Remington?

[tojan19]

Does anyone have any load data for IMR 4320 and the 260 Rem. I'm putting together a new rifle in 260, never loaded for it before. With H4350 impossible to find right now, I need to use what I've got available. I have Varget and IMR 4320 on hand.

I'm looking at ordering some Lapua Scenar 139s, Berger 140s, Hornady 123 SST, and Barnes 127s to try out. Midway has them all in stock right now.

The Hodgdon website only has 2 bullets listed for 4320. Neither of which I'm interested in.

I have several pounds of IMR 4320 I tried in my .260. I could not get the velocity w/o running in to pressure issues and groups were nothing I could live with, so I shelved it. RL 19 will do well as will IMR 4350 and Superformance. Good luck!
