marlinloverFinally slugged some bores today...
I slugged some of my bores the old Lyman/Ideal manual way. I cast bullets for each cal. with pure lead.
Oiled the bore and the bullet, and made myself some steel rods to tap em' through. This is what I found:
M1917 Eddystone .312
M1917 Remington .309
454 Casull Bore .454
454 Casull throats .454 1/2
Winchester Mod. 94 45 Colt .452
For the .45's I've got a .455 LFN 320gr (gc) LTB
WW- cast at .456 327gn
For the .30's I've got a 311284 (gc) 210gr Lyman
WW- cast at .310 216gn
What would you guys recommend for sizing dia. for these bullets and guns?
I'm thinking just run through the sizer the same dia as cast.
Problem is I only have sizers in .309, .308, .452, .454.
What sizers would you use?
Can't wait to get the Fat-30 for the Eddystone, and my micro groove .30 cals...

woody1marlinlover, If it was me, I'd start by lapping out some sizers. I'd turn that .308 into something bigger starting at .310. A couple thou. is easy to do. I think you know the answer for the Eddystone. You prob'ly need a bigger boolit and sizer to go with it. Each gun IS an individual, so try what you've got. Leading is easy to get out if it doesn't work. Match the cylinder throats for the Revolter or go a little over if they'll chamber. The same with the rifles. IMO bore slugging is only half the job. What is the throat diameter? Match the throat diameter if filling the throat requires a larger boolit than the bore requires, so be it. If it'll chamber, it'll shoot. For instance, if your Winchester 45 will chamber a .454, that's what I'd use, provided it's not a jam fit. Your chamber throat needs to be filled, but not to the point where it's jammed in and pressure goes sky high. Can you slip a .454 boolit into a fired case? If so use it. Regards, Woody

marlinloverGreat Woody,
I was just wondering 5 minutes ago if I could make those dies bigger. How do you lap them?
...and your saying even if the bullet is much bigger than the bore, if it will chamber it will work well?
How does that work with a Stoney Point AOL gage? What I've been doing with all my rifles is setting the AOL with their gage to .020 back off the rifling.
If the chamber throat is much larger than the bullet, but I'm still right up close to the rifling, does that mean the bullet just will expand to much?
Sorry for all the questions here, but being somewhat new at the science, I'm trying to figure all the finer points of this stuff out.
