Hello folks, I'm interested in purchasing an expander plug from NOE. I'm wanting to try loading .431 and .432 boolits for my 44spl, which has generous throats. I'm using RCBS and Lee dies at the moment, but no matter what I try, my boolits swage back to .430 once they are seated. I hear NOEs plugs can help this problem.
I'm a little unsure about what size to choose. I see a .431 x .427(P), .433 x .429(P) and a .434 x .430(P). Any explaination of these sizes would be helpful. I called and emailed NOE, but I think they are probably a small company and don't have a great deal of time for phone calls and emails.
