Powder substitute for IMR 4064???

Interesting. I've never used 4320.

Decisions...

Before settling on IMR4064 for 168gr SMK in 308, I did some testing on N-140. FWIW, from my files: 43.5gr powder, 5 shot tests, MagnetoSpeed:

N140: 2715fps, ES=16, SD=8
IMR4064: 2712fps, ES=not recorded, SD=12

Several tests on both powders @43.5gr are recorded there - all are in the same ballpark. I like both powders, and in other calibers/weights if one works well for me the other will work too. I use the N-140 in 167gr Scenars so there's no language barrier

I guess weve forgotten about AA2520. I use it with 175gr and get outstanding accuracy @ 300 meters. Clean burn as well. H380 is a bit slower but its a real sleeper in the 308. Of the two H380 is quite available, 2520 I dont know. You may have to dig around to find loads for these but they are in print.

I agree. I like the H380 for .308 168 and 175.

Try a pound of accurate 4064. I used tit to develop a load for a 30-06 once and it shot very good.

When I couldn't get IMR 4064, I tried AA 4064. It works very well . . . perhaps 0.5 grain slower than IMR 4064 in my 6mm Rem. but just as accurate.

Once I tried it, I bought several pounds of it.

I am surprised nobody has suggested Reloder(R) 15 as sub for IMR 4064.
Also from our line, AR-Comp(TM) is a slightly faster burning, but great substitute in 308Win. AR-Comp is closer to the 4895's in terms of burn speed, but delivers outstanding temperature stability. Give it a try, if you have not already.
Shoot well,

This. ^^^^^^^

I'll put in another vote for H-380 in the 308. 45Grs w/the 175 Hornady and Federal Match primers.
I could occasionally keep 5 on a postage stamp size target at 200 w/a factory 700. It drops fantastic. LDS

Just where do you get RL15???? I'd buy at least 16 lbs for a reasonable price.

If you can't fin d RL 15 try Norma 203B Most manuals list these powders as twins

It seems to be coming back around now. I picked up 10lbs (not sure why the RL powders are 5lb jugs instead of 8lb) not too long ago from Wideners and Bruno's had it in stock recently as well.

Not all Reloader powders are 5 ponders. The R33 and R50 come in 8 LBS. Matt

I have also used Accurate 4064. Charges turned out a little different than IMR 4064, accuracy was similar. It is a shorter cut powder and metered much better however.

I have "heard" that AA4064 and IMR 4320 are basically clones, and IMR 4064 is a little bit slower.

Another great Alliant powder is 2000-MR. Very clean burning, excellent velocity, meters great, and is less temp sensitive than many other ball powders. RL-15 is another good choice.

Lots of shooters in Fclass have tried Rl 17 in 284 but not using it any more IT SPIKES IN HEAT CAN BLOW PRIMERS
I have never seen anyone use IMR 4064 in 284.

In 308 win I have seen it spike using RL 15 for me you can not use double base powders on hot days.

For your 284 wi H 4831sc is the powder hands down
for your .308 win Varget or H 4895 is the powder hands down
