I'm looking for a quality powder measure that will accurately throw more than 70 grains.

I'm loading for a 338WM using a Dillon with the mag powder measure. About 73 grains RE-19 is its max. and it is not that precise. About +/- 0.3 grains with H4350 and +/- 0.5 grains with IMR4350.

Any recommendations will be appreciated.

Bill

Good luck, never seen one yet that can throw that good even from dillion. I hope you find one so you can tell me.

Heck, be glad you can get +/- .5 grains with IMR 4350!! I can't get that good with 55 grains!! Your best bet with a long extruded powderwould be to set the powder measure about 2 or 3 grains below what you want, throw the charge, and then trickle in the remaining two or three grains. I just don't think there is a powder measure out there that will throw an extruded powder to within +/- .1 grain.

bigcountry and charliebrown,

thanks.

I should has stated that my variance test was in the range of 50+ grains - for the 30-06.

The 338 loads are thrown a little short and trickled on digital scale. But this is a real bore!

Any experience with RCBS "Uniflow" or the Redding powder measure - I forget its name? The RCBS advertises capacity up to 110 grains. Can they throw +/- 0.3 grain in the 70+ range? (I think you have already answered that - NO.) <s>

Thanks...Bill

I recommend that you just get used to dribbling the final grain or two for the large capacity rounds.

For my .375 H&H I dump my measure twice into a scale and then dribble the balance to suit. Unless one does a lot of large capacity case shooting one can get along this way easily.

I usually shoot the .375 about 50 times a year to keep in fun and giggles and the smaller powder measure works just fine for this trick. I gave up looking for a more accurate measure years ago....there just isn't one unless you're throweing ball powder and then almost any measure works well.

I have found it best to throw two small charges, instead of onebig charge. Setyourpowder measureat 36-grains & throw it twice.Then trickle the last grain.
I am sure you will be happier with this method.

bill, I got those and there is no way I could have thrown those accuracte loads with them in my 300RUM. Usually throwing 82-100gr. Ramshot maybe.

RCBS " UNIFLOW" , charges from 0.5 grs of Bullseye to 110grs of 4350.

The Quick-Measure will probably take care of you, but it's kind of pricey. I don't own one, but I've heard from some who do and they think it's great. Here's the link:
