problems with bullseye metering

mnhntr · May 9, 2012, 10:35 PM

Anyone use Bullseye in a RCBS Uniflow with micrometer? I normally use A#5 for my 45acp loads but had a pound of Bullseye on hand and decided to try it. The A#5 meters better for me. The Bullseye was anywhere from 0.05-0.15 difference in each load.

I'm using the small micro adjustment screw (part # 98902) and it doesn't seem to vary that much as I recall.

I had same issues with bullseye. I switched to AutoComp and HP-38. They both metered better for me. Bullseye is a great powder I just couldn't get it to meter well at all for me.

Double tap that handle up and down.

Thats what I do, double tap and no problems with bullseye at all. I am using a rcbs power dump using a digital scale to set it up and checking every 5th load.
I love bullseye and also unique

I had a lot of trouble with Bullseye when I first started reloading for pistols years ago. It would get in the gap of the "pistol chamber" on my Redding No 3 and bind. I went to other powders like 700x and 231 for a long time.
But I wanted some light loads and Bullseye is very good for that.
As I have my Dillon set now, it meters - 0, +0.1; reading either 3.5 or 3.6 grains when I check a load. That is plenty close enough. My scale does not even read down to the .05 grain level so a variation of .05 to .15 would show up as 0 to 0.1. Which is what I am actually seeing.

Motor on, you are doing fine.

thanks for the replies

Also make certain that you have the pistol rotor! The larger diameter rifle rotor will not give you good drops below 10 grains.
