I picked up 8lbs of it today cheap.
I plan on using it with my IMI brass and 47 gn bullets in my ar10. Anyone have any experance with it ? |

I throw charges of IMR-4064 with my Harrell's powder measure. It's crunchy for lack of a better term. Some kernels get cut in two when thrown.
It's a very good powder despite that shortcoming. I don't load full metal jackets, but do use IMI brass. 41.5 grains of IMR-4064 is a maximum load when using 168 grain Sierra Match King bullets seated @ 2.810". Winchester primers. Start around 40.0 and work up in .5 grain increments in .308. I would think 43.5 is going to be close to maximum when using IMI brass and 147/150 grain bullets. Again start lower and work up in .5 grain increments. .5 grain works out to a 30/35 fps increase for each .5 grain added. Look at 2750 fps as a working maximum when fired from a 24" barrel, 2650 fps from a 20". Once you can get past the idea that it doesn't throw very consistently from a measure you'll discover it still shoots very well in spite of it. 147 grain FMJ bullets are not known for accuracy. Any of Sierra's Match Kings from 150, 155, 168, 175 and even 180's will hammer with this powder. |

Yeah - it meters HORRIBLY through the Dillon powder measure. I bought 8lbs during the powder drought a few years back... NEVER AGAIN  . Once you get it in the case, it works just fine.Results are determined by technique. I throw my charges of IMR4064 using my Dillon 550B's powder measure. I get SD = 0.14 gr about a nominal of 42.0 gr. For me, this is adequate for everything (based on chronograph results and group size at 200 yards). Handloading did no better in either regard. I used to use 147 gr FMJBT's for practice at 100 yards. With that bullet, you should save the effort and throw charges. If the OP is using that bullet, he'll never see any difference between thrown and weighed charges. |

IMR 4064 is one of the all time great powders for .308/7.62*51 semi autos. My M1A just loves it.
I load on Hornady LnL AP using their powder drop, have found it very consistent, always within +/- 0.1grs. Took a while to get comfortable with that crunching sound when grains get cut, but well worth it. |

41.9 over a 175 mk. Great powder and makes you buy an RCBS chargemaster. I'm using a charge master . Then you got it kicked in the a$$. I use IMR-4064 with 150gr "class" bullets in .308 Win. You'll love it. Especially since you got a deal. The hunting load for my Remington 742 was pretty warm but shot very good. I'm not where I can look at my data but I'm pretty sure it was around 45gr with a Hornady 150gr SST plus this is in LC-67 -LC-74 brass. You don't need and probably don't even want maximum velocity for your 147gr "fun" ammo. I'm just letting you know that you may be able to go higher if your accuracy node dictates. Motor |

Lee perfect powder measure cheap, and i bought one to use for the 16lbs of 4064 i stashed away. Throws great loads for all my large rifle calibers - .308, 30-06, 7.5 swiss, .303, etc. Came here to post the same exact thing! Lee Perfect Powder Measure. It has rubber or vinyl sweeps or something and measures long grained powders nearly as easy as others throw ball. And cheap enough to buy extras instead of recalibrating when you switch calibers. |

Quoted: It's more the bullet than the powder in this case. I do like the powder. I'm going to pick up some Sierra 168s to push down range . Quoted: Quoted: I've had great results with it. It is crunchy, but that doesn't seem to matter. It's more the bullet than the powder in this case. I do like the powder. I'm going to pick up some Sierra 168s to push down range . I couldn't agree more. With a decent bullet, I have yet to be disappointed with 4064. |

I didn't have an electronic dispenser back then and had to hand trickle. I didn't hand trickle practice ammo. My Uniflow would go as much as 1 grain in either direction from the designated load. This however did not have a significant difference in group size. Motor |

I have a metric crap load of IMR 4064 so it's my go-to for .308. My close range blaster 3-Gun load is 39.0 gr with a 147 gr FMJ. It's pretty accurate, very low recoil and really easy to shoot fast. My go-to medium range accuracy load for 100-500 meters is a 155gr Nosler CC with 43.5gr and gives me 2,600fps in my PWS Mk216. |

Quoted: Supposedly you can use it in an AR too, but I haven't done so yet, and no experience to say how well that works out. 25gr under a 52gr SMK Both good 100yd loads from a 16' carbine in prone. Just a bit slow. I'm currently working with 40.6gr under 190gr BTSP AND 180gr SBT for a Palma throated Mauser. |
