[QUOTE="2ndtimer, post: 2553427, member: 24759"] Given that you have a good quantity of H-450, I would consider trying it in your .270WSM. My old loading manuals Speer No. 10, Hornady 4th Edition and Hodgdon Data Manual No. 25 from 1981, 1991 and 1988 respectively each show maximum charges for 100 or 110 gr bullets for the .270 [B]Win[/B] as 62.0 or 63.0 gr of H-450. I would start my [B]WSM[/B] loads at that level and work up one grain at a time and watch for pressure signs. In my quick research, it would appear that Ramshot Hunter is slightly quicker burning than H-450, and my Lyman 49th Edition shows a max load of 68.0 gr of Hunter with a 110 gr Sierra bullet for the .270 WSM. You should be able to go 68.0 gr of H-450 with relative safety, even with the mono metal bullet. And probably several grains higher, carefully watching for pressure signs. It is your firearm, your eyes and fingers. I have loaded a few times without specific load data for a particular cartridge and powder, extrapolating data from similar cartridges and similar powder burning rates. It would be interesting to hear your results, if you choose to give it a try. You could even give the H-450 a try in your 22-250. My old Speer and Hodgdon manual both list loads for that cartridge with H-450. I liked that powder with my old .243 Win. [/QUOTE]
