In the midst of working up loads on several guns I just realized I’m down to 1/2 lb of IMR 4064. This is all I’ve ever used in my swifts with good results. What are some good replacements? I mainly shoot 52-55gr bullets. Not looking for speed, accuracy is the most important to me.
Thanks.

Howdy ,
+1 on what Gary in MD said.
WW760 worked superbly under Hornady 55SX in my “ .22-35 Remington “ wildcat
( 49.4gr H2O capacity ). I also used FED Large Magnum Rifle Match ( GM215M ).
These days…. it seems as though Hodgdon is tapering off on WW760, and ( at least local area here ) 6.5 StaBal has more or less replaced it. I don’t see the former powder on the shelves, but do see 6.5 StaBal available in-depth; frequently.
I currently have a new .224” cal gain-twist barrel on order from Bartlein. This will make it my 3rd barrel to be chambered in my .22-35 wildcat.
Since I already knew the max charge of WW760 that I could shoot in my .224” cal wildcat, I recently performed range work to find max charge wt for Hydbrid 100V: and for
6.5 StaBal…. using my original “24 Hart SS 1-14 take off barrel. These 3 powders are aligned shoulder to shoulder on burn rate, and I threw in H100V testing mostly to see how far it’s max charge weights varied from those for 6.5 StaBal.
After deliberate, cautious, detailed range testing, I found out ( to my suprise ) that the max charge for 6.5 StaBal under 55SX and using GM215Ms was only .1gr more than the max charge I had already well established for WW760. In actuality, if I would reduce the max charge of 6.5 StaBal by .1gr to adjust for shooting in higher ambient temps, my max charges for WW760 and 6.5 Stabal would be the same in grain wt ! I talked to Hodgdon about this closeness of these two powders, and speculated whether 6.5StaBal
is basically WW760 w/ the addition of some special coating ? Hodgdon firmly asserted this was not the case… and that 6.5StaBal is a new, stand-alone formulation.
I have great confidence that I will be able to supplant use of WW760 with 6.5StaBal,
for my impending application.
I myself have not been a reloading components “ hoarder “.
Notwithstanding…. I have already provisioned myself w/ 4,000 GM215Ms, and to start out with… 1,000 55SX bullets; and 5 1lb containers of 6.5 StaBal.
Best of luck in your endeavors !
