IMR 4064 for 22-250?

Have any of you had any experience using IMR 4064 in the 22-250? Looking at the 3rd edition Sierra manual I see that it doesn't produce the highest velocity, but Sierra recommends it for their accuracy load for every bullet weight. I will most likely be using the 60 grain Vmax or 60 grain Berger.
 
I use 4064 in my 223 for 69gr SMKs, it's the most accurate load I have. I also use 4064 in my 7.62x54R Russian Mosin Nagant. Both are very accurate loads.

It will work fine.

IMR-4064 is one of the most recommended powders for the 22-250, buy guys who use it and get good accuracy with it.
You'll just have to try it and see for yourself if it works in your rifle. If it does work, fine. If not, there are several other powders that you can try.
My 22-250 likes Benchmark and Varget equally well with 55 grain bullets.
I do have some loads worked up with 60 grain bullets using RL-17 and 4350. Ackleyguy who posts here recommended the 4350 loads. With RL-17 being new, and having the potential for better velocity, I decided to load some 60 grain bullets using it. The burn rate of RL-17 is very close to IMR-4350.
Good luck with your load testing.

That's the powder that many of us in this area use for the .22-250 and 55 grain bullets. It give decently high velocity, excellent accuracy and seems affected less by temperature drops than some other ball powders commonly used in the .22-250, such as H380.

RL 15 is the best 22-250 powder IMO,



I can't argue with that. I use '15 in my '250's with bullets from 40gr to 75gr.
 
It works very well for me... and I've tried several powders (H380, IMR 4895, Varget, RL15, W760, and even IMR 4350 and even IMR 3031)... and many of these do work very well, but the 4064 gives the overall best results for me.

Thanks for the input guys! I've used a number of powders in my 22-250s. IMR4895, IMR4350, IMR4007ssc, varget, big game, but somehow I've overlooked 4064. I'll be picking some up and giving it a try.
Martyn do you have any load info that you can share using RL-17? It's available here, but I haven't seen any 22-250 data.

Yes, I have some RL-17 loads. But, I only used it for 60 grain bullets, along with IMR-4350. I was discussing working with 60 grain bullets in my 22-250 with Ackleyguy who posts here. He gave me the low down on using the 4350. Since RL-17 came on line, and since it is very close to 4350 in burn rate, I just used the 4350 data from the loading manuals. The promises of RL-17 giving higher velocities is something I could not ignore. IIRC, Ackleyguy uses 39.0 grains of 4350 with 60 grain bullets. That's at the high end for a powder charge, so I started well below that for openers.
I had read on another Forum that guys had actually used IMR-4350 load data when working up RL-17 loads, so that is the basis for me doing the same thing.
For 55 grain bullets, I'll stick with a known load that does shoot well in my particular rifle. It is 32.6 grains of Benchmark with Sierra's 55 grain HPBT, with Federal 210M primers. I shot a 1/4" group at 100 yards with this load using a 36x scope I use for load development. That fine group makes my 22-250 my most accurate sporter. But, I gotta say the Varget was VERY close to the Benchmark load in accureacy.

Edit to add: I seat bullets .010 off the lands, so that's the seating depth for the loads above. That .010 distance is from my centerfire benchrest shooting days. It worked then, and works now, where magazine length will permit. Magazine length dictates otherwise.
