45 Plain-Base checks with NOE 460-405 RF

After working with itty-bitty 22 checks, handling the dinner-plate sized 45’s are a pleasure…

Here’s the 45R-PB checks as made with the Pat Marlin tool.  This is 0.008 Alu coil.

This is a Plain-Based gas check, for use on non-gas checked boolit bases.

Just to show how well these things grip the boolit, I even placed some on already sized (459) and lubed NOE 460-405-RF, here you see the check easily slips on the base, and to the right, here’s one that is crimped-on, by pushing base-first thru a Lee 0.460 sizer

Note, pushing nose-first in a Lee PT sizer does not work, it shears the check.

Even with those waxy boolits, I can’t get the check off, but the base is not as perfectly flat as I’d like. I think push-down sizing in the Lyman 4500 Luber-Sizer would be better.

And it is. This is a perfect flat base, crimped-on so tight, I can’t get it off.  That was with a 459 Lyman lube-sizer die (push-down sizing).

Of course, the checks should be applied to a fresh, unlubed boolit, and Pat recommends doing so on freshly cast boolits.  I have already used these at 100 yards in target and max loads with beer-can material (not ideal) in my Marlin 1895, and accuracy is superb.  If they are coming off, I can’t find them and accuracy is great and the bore looks as clean as if I fired Paper-Patched..  But, I will try to get some boolit recovery of boolits checked with this thicker Alu material in wet newspaper when the weather improves. 

again, just posted for interest.
