I decided to take today and tomorrow off and work up some loads with my Checkmaker gaschecks in 30 caliber.
This past Christmas, I purchased my wife a Browning BLR Lightening in 308 Winchester as a present and we had not got a chance to fire it. It's about a 1994 year in mint condition. Looks to be hardly fired. Mounted a Nikon Monarch 2x7 on it, and cleaned the bore of copper down to bare metal.
What a nicely ballanced rifle. The only problem is the trigger pull. Darn harder than I prefer as it's probably 6-8 lbs. Definitely not bench friendly.
First I would like to clarify some details with our Checkmaker die sets. I read some posts over on another forum about my release of the dies, and the poster had made a few comments I would like to address. I'm glad they are at least talking about it.
One of the assumptions is our gascheck is formed without base support as the male die comes down and forms the check in the female die, thereby creating an "unsquare" based check.
Nothing could be further from the truth as our "check ejector" -as I like to call it, serves as a solid base (backed by the rigidity of your press) that the cut disk forms against- creating a square, concentric, flat based gascheck. No hollow base forming here. All of our future caliber Checkmaker die sets will have this feature- even the 50 caliber.
Below is a picture of the "check ejector" in the female die. The large flat head of the ejector sits on it's own shelf creating a solid base that transfers to the press ram.
Next is a picture of boolits I whipped up today from my LEE 311407 GB mold checked and sized to .310 with LBT blue soft lube and Checkmaker .010 soft copper gaschecks. My pics turned out bad this evening, but notice the "Square" flat bases.
I also perfected my design on the LEE Classic primer arm replacement (shown). I milled this out of aluminum flat. It sets in the ram slot and works flawlessly ejecting your gascheck from the die, then brining it to the top so you can easily remove it. (sorry for the blurring pics)
