| I am running out of my Varget and don't know when I'll be able to get anywhere that carries it. So, I have a new can of IMR 4064 (given to me by a friend). The lightest Sierra bullet that the Hodgdon's website list for this powder is 53 grains, but an old Sierra manual I have has a load for their 50 grain Spitzer Varminter bullet which I like to use. I was wondering what anyone thought of this powder for reloading 223's for use in an AR-15? |

Yes, please look back a couple pages. This subject seems to come up once a week. edit, Maybe it doesn't come up that often after all, only found 1 recent thread, http://www.ar15.com/forums/t_6_42/420912_IMR_4064_old_vs_new_.html&light=IMR%7C4064 So carry on. |

Yes, please look back a couple pages. This subject seems to come up once a week. I'm guessing that it has something to do with it's availability. I've seen it on the shelf more frequently than anything else in the last few months. It has become a "Better than nothing" powder. I know I picked some up for myself because my keg of H4895 is getting empty, and I'd rather have something to use if I can't find any more as a backup for .308 shooting. |

*I'm not saying this is a great group by any means, you'll see what I did in the rest of the post.*  I feel like I could certainly tighten this group up considerably with one of my other AR's with some magnification, bipod, and squeeze bag. I might try that out this weekend. I was pretty impressed with what I was able to do with only the second batch of reloads I have ever loaded, without even really trying for any great accuracy. I'm pretty confident that IMR 4064 will at least make a great plinking load if nothing else. Looking forward to shooting the rest of these for a little better accuracy to see what they will really do, I have 30/50 left.   |

I have a ton of 4064, so I have started to experiment with it a little in .223. I was trying to work up a load for my heavy barrel rifle and shot this group with 23.1 grains of 4064 behind a Sierra 69gr. Matchking FMJBT.
This is a 10 shot group, shot prone off a bipod with no rear bag, just using my off hand under the stock for support. I know I pulled at least one of the shots outside the main group. I only had the 10 with this powder charge at the time, but have since loaded up some more and when I get a chance I am going to try some more to make sure this wasn't just a fluke. Hopefully, this load will be a winner in this rifle.  TgtGfx by john.nikon, on Flickr

| This info is really encouraging. I will work up some loads today with this IMR 4064. My FFL dealer called and the gun is on the UPS truck! He will get today and I will have it tomorrow. I'm going to put an old Japanese made Tasco World Class 3.5x10x50 scope on it using a Nikon M-223 base. Looking forward to getting a real coyote killer worked up. No more having 2 or 3 of them come in and only being able to put one on the ground! |
