Replacement for IMR 4007

[ballpowder]

So I am down to my last pound of IMR 4007 and I am looking for it's replacement. I have several rifles that like it but it was unreal in my 22 Cheetah at 79 1/4 clicks. H380 nearly matched it perfectly in velocity but I would like a stick powder. The powders that all have the same burn rate which I call "The Vargets" including: 4320,4064, aa2520, w748, varget, reloder 15, blc-2, and I'm sure I'm forgetting a few, are all good powders but leave air space in case and aren't at the level of 4007.

Some cases I'm considering are reloder 16, n540, 203B. I need advice. I live in Alaska and if I'm going to order a keg which makes it worth all the shipping cost and aggravation then I would like your options.

Thanks

Tim

RL-16 is just about right in the middle of IMR 4007 and H4350. Both are pretty close in burn rate and I think, at least from my experience, which is limited with RL-16, that RL-16 is a half a shade faster than H4350 and a shade slower than IMR 4007. It should do nicely in your case with 1 possible "fly in the ointment". IMR 4007 has very small powder kernels and RL-16's are considerably larger. The load density won't be near as tight as 4007>>>but you may not need the density to make it work well.. AND you will have the benefit of a VERY temp stable powder.. I would give it a shot..

Cool. That's the kind of info I'm looking for.

might also consider imr 4451, similar to the 4350's

and imr 4166, similar to the 4064

I think badger and h4895 are there pretty close. I went from the 4007 to arcomp and h4895
