IMR 4064 in .257 Roberts

Sara Noh · Mar 1, 2009

Anyone load IMR 4064 in .257 Roberts? I load it in my .35 Whelen and it gives very satisfactory performance. In the interest of keeping things simple and not stocking lots of different powders, I would like to use IMR 4064 in my .257 Roberts. I am seeking input from shooters that use this powder in their .257, not interested in hearing about other powders, just your experiences with 4064. Thanks.

well, IMR 4064 works great in my 35 REM. I suspect that it would work great in almost everything,

Uh, that isn't necessarily true! Yes, it may burn in any cartridge, but that does not make it a good or safe choice. Without going into a lot of detail, it is always best to consult a good reloading manual and select a powder that is recommended for a particular cartridge.

I haven't yet, but after looking at Hodgen's website, it looks like a pretty good possibility to me.

FYI - A quick check of an IMR handloaders guide shows IMR 4064 to be an acceptable powder for the .257 Roberts. Sorry, I've not used it in the .257 Roberts cartridge but it does look like a good bet.

As I have a new can of 4064 and a few boxes of 100 gr Sierra bullets, I might just have to find out.

I have had great success with 4064 in the .257 Roberts. I use 42.0 grains with the 90 grain Sierra in a Rem 700 classic. Very accurate. Never chronographed it but it shoots very flat. I have had really good groups with it out to 350 yards.

I reach for the can of IMR 4064 as my first choice for loading the .257 Roberts. I use 36 grains with the Sierra 117 grain spitzer boat tail bullet for velocities a little over 2600 fps, a combination that is effective on Texas whitetails.

This sounds waaay over max to me!

Hodgdon's load data shows 35.5 grains max. with a 120 grain Sierra HPBT. Their data shows this load produces 2695 fps out of a 24" barrel.

Sorry, it was suppose to be 36.0 grains.

I have had a .257 Roberts for years (I now have two of them) but haven't shot it much in recent years. I shot it for varmints and also for black bear hunting in Canada. We are not allowed to use rifles for deer in Ohio so all of my deer kills have been with a handgun.

4064 does not measure well (large grains) but I use an equally large grained powder for full power loads with 115 gr Noslers. It was 4350 and 4831. I threw a close load with the powder measure, then trickled until the right charge was dropped. You could do the same with 4064.

4064 was a very useful powder for the 22-250 also.

At any rate, using the proper bullet, the .257 Roberts is a VERY nice cartridge for deer and black bear (if your state allows rifles) as well as a solid performer in the varmint fields.

I personally believe you are handcuffing yourself to a single powder. I have a Rem 7600 pump that will shoot Hornady 117gr. bullets into 5 shot 5/8" groups at 100 yds. with a less than max loading of IMR 4350 into Hornady brass. I've tried some other powders, not 4064, but this rifle does best with 4350. I trickle my powder into every case. You also need to find that sweet spot for COL.

IMR 4350 is said to the the "Classic" propellant for the .257 Roberts but in my particular M70 featherweight, I get the best results with a 117 grain Sierra SPBT and near maximum charge of IMR 4831.

257 Roberts, 75 gr. Hornady HP, 44 grs. IMR 4064. This was used in a 1-14 twist barrel.

I love 4064 in the 22-250..........Creeker

Yes, I have used 4064 to load 100 gr. Sierras in my Rem. 722 .257 Roberts, and I thought it worked quite well.

I tend to hunt in heavier woods, now, and prefer heavier bullets. I usually load 120 gr. Nosler Partitions in front of Reloader 22.
