I am trying to tone down a 45 LC load, for Cowboy Action Shooting. I had loaded some practice rounds utilizing a 200g RNFP lead (lubed) bullet. (This bullet is produced by an outfit called “BulletWorks”). I used Starline brass, CCI 300 primer and charged it with 7.0g of Unique powder. I took these practice rounds down the road to my shooting spot, and they seemed to work fine.

I loaded up about 300 of these, and yesterday headed off to my first CAS, at a range about 60 miles from my home.

The problem? At the shoot I was plagued with inconsistent performance of these rounds. On multiple occasions, the bullet would just barely make it out the barrel (and they had preformed very well in my practice session!)

I am wondering if the light load does not sufficiently fill the case, resulting in an inconsistent powder ignition…? Would the use of a Magnum primer help?

As I loaded these I used a powder measure, checking every 5 to 10 rounds on the scale, and never found ANY to be under charged.

Any help would be appreciated!
