I've been trying to get an accurate 43 grain measure of H4350 with a Hornady powder measure and can't get closer than .5 grain variation from measure to measure over twenty loads. Is there a trick to this? How are you getting an exact load measure?

Is there a trick to this? How are you getting an exact load measure? I use an RCBS Charge Master but I have used an RCBS UniFlo in the past with good results. I've never used the Hornady measures. Ritch uses the Harrell's for his goodies. In the past prior to the CM I would dump a close charge and then tickle up using an electronic scale. It is a lot fast than the beam balance I started with back in the 70's. Another thing, scarce as hen's teeth, is you might tr to find some H350 SC. It was developed just for the issue you are having.

Read about using the programmable dispenser 1 grain low. Transfer to a balance scale and trickle to exact grains. The dispenser can keep up fairly well.
I don’t remember where I read it but that will be my approach if I run into that issue. I have a Chargemaster Lite and RCBS 1010. Just got the Chargemaster Lite and used it once and it was within .1 grain. I use H4350 and H4831SC. I check every one on the balance scale anyway until I have confidence. Then sample at 10.

Looks like you have a good system. I'll check the electronics with various check weights occasionally but life is way to short to use a beam balance.
Plus or minus a tenth on a load is pretty inconsequential for my needs out to 500 or so and my guns can except that spread in shooting groups or the load was not good to start. IMHO brass consistency is far more important than a tiny powder variation.

Agree with your experience Greg. I would be nervous with OP .5 grain variance if it were at near max loads. .1 grain - not so much.

In some bigger 308 sizes assuming not a fire walled load it would be no big thing. H4350 has always been a bit problematic hence the SC version. I can guarantee you in some of these hot 17's and 20's 0.5 can be OUTSTANDING on the chronograph but you get a smoking hole where the primer use to be!! Greg |

I have a Redding next to my single stage...but I still trickle the last few kernels of powder for each case. I have a Hornady on my Load Master which is designated for making 5.56 plinking ammo and I use a Lee pro auto disk on a second Load Master designated for handgun ammo.

Greg Well if you are going to use any powder measure you need to find a wide powder charge node. Short range benchrest has used them for decades with great success. Yes there is a trick to it. Lots of practice and a consistent throw. With practice and the right powder you can be as accurate as a chargemaster. Don't try it though with a long grain stick powder. |
