Re: Lee challenger breech lock press opinions
"Fuzzball, Care to share the specifics of your test?"
Jake, thanks but no. For the same reasons I question the vailidity of the referenced tests, such a limited base is statistically meaningless. To anyone but me and MY presses anyway! And, really, as I mentioned, I didn't find any significant differences in the run-out anyway.
Well, okay, to help make my point and without mentioning the specifics of run-out levels, I actually tested two Lymans (one a well worn "Spar-T" turret), four Lees (two were the little "Reloader" types, one was a "Hand Press"), my then new, tight Rockchucker II and a thirty year old, very loose Herter's 3 that belonged to a now dead buddy. My test series was done maybe 15 years ago when I first got my concentricity gage and was going crazy with it. (Don't know if I could even find a record of it now!)
All the presses loaded the same twenty cases with the same (inertia pulled) bullets pushed back into the same cases, done with the same set of common type/brand of dies as precisely set up as I could match them to a saved dummy round from the first series.
Results? The average of each set of run-outs was not identical but it was VERY close. Not what I expected but that's what I found.
That's why I find it so hard to understand how a press could produce up to .010-.011" run-out, all by itself.
