    Imr 4064

    I have a chance to buy some of this. I have a Hornady LNL and want to know if this measures out evenly and if this powder produces good results. It seems to have a wide range of use and would fit my intent to build a 308/260/7mm08 platform. It also appears to function in .223 and several others. Grab it now or wait for better?

    My opinion? If you're looking at IMR 4064 for that reason only, jump on some IMR 8208 at Powder Valley right now.
    It's the ONLY powder from IMR for rifles that I'd buy. Ever.
    Technically 8208 isn't an IMR powder, it's a Hodgdon Extreme powder.
    Do you really think we want laws to be observed? We want them broken. There's no way to rule innocent men. The only power any government has is the power to crack down on criminals. When there aren't enough criminals, one makes them. One declares so many things to be crimes that it becomes impossible for men to live without breaking laws. Who wants law-abiding citizens? Pass the kind of laws that can’t be observed, enforced, or objectively interpreted - and you create a nation of law-breakers.

    It's showing oos. I guess I can just be patient and wait. I've got some other things to play with in the mean time.

    If you're running heavies in 5.56, you could consider Varget as well. 8208 is a bit faster than Varget, your call. Both are excellent for what they do.....
    My next-up choices are H4895 and Vihta N140 (tied) - but the Vihta is going to be expensive and the H4895 isn't nearly as stable in heat and humidity as the first two.
    Hope that helps - sorry about the 8208 being gone.
    If I hadn't had to pay 230 bucks on the kid's medical today, I would have picked up a couple of jugs myself!

    AA2520 is pretty good on heavy .223 loads. Not so good on light tips. It's my go to powder for .308 though.

    I ran AAA2520 for a pretty good while, pushing 175 SMKs down the barrel and some 69 SMKs as well.
    If you're not running 'edge of safety' loads or are concerned about significant velocity changes due to ambient temperature variations, then it's a good powder.
    It does flow like water through a powder thrower!
    But going from 'cold enough the snow on the ground isn't melting' to 'this is why they start shoots in Nevada an hour earlier in the summer', you'll see a significant deviation in your zero at range.

    But that's just me ;-)
    For battle rifle or practice ammo (especially limiting the range to 500 and in), AA2520 would be a very difficult powder to beat.

    I loaded 30 rnds of 53 g vmax with IMR 4064 , this past weekend. Used min load data and they were filled to the shoulder. I'd say they were compressed a lot. Brass was flying about 20 ft or more , on setting 2 ( normally brass flues about 10 ft). They were half decent accurate. CFE 223 is my best powder so far , using 26.2 g with a 53g vmax , I'm getting 1 Moa .

    This is my go to power for 762x51, 178r match king, 42.3 gr of 4064, this load brought my POS scar17 from its typical 18" group @ 100 to about a 2.5". Yes im overblowing the 18" group, but the heap of shit is typically 5" or worse, that is of course when it cycles.
