IMR4320 isn't nearly as slow-burning as IMR4350, and in fact is almost identical in burn-rate to IMR4064. You can find this out easily by looking at Hodgdon's on-line data. Rarely will maximum charges of 4320 and 4064 vary more than a grain in the same application, and often they'll be even closer.
Thanks You Sir:
The only rifle I ever used 4320 in was the 35 Wh.
4064 was one of my FIRST powders BECAUSE JOC used 52/52.5 grs of it in 06 with 150 gr bullets.
Also 49 grs of it in 270 with 130s. I'd guess that DATES myself, huh ? lol
I appreciate this info from you because of your experience with many more rifles/cartridges/powders than I have.
I'm far from a newbee but I'm not in the BIZ.
THAT IS GOOD NEWS for 35 W shooters -- 4064 is close to 4320 ! I'd like to have known that then.
I also know there are newer powders some are using in the Whelen but I'm not sure they are better. ???
Thnx Again
