.222 Rem TC Contender 8" Octagon Factory Barrel
Bore: .2245~ (approximate)
Groove: .2250 (3 measurements all came up the same, three different points on the cast)
Throat: .257
Bore slugged at the same time and came out the same as the chamber cast. Groove, which I can accurately measure came out to .2250 on the nose. Bore is an estimate as I don't have any way to measure that small a spot except with Calipers.
Could someone advise what I should have my Lee push through sized to? .225 or .226?
My Lee Bator mold drops Pure at .225 average of 25 boolits.
I plan on using Pistol powders and dacron for a 100% fill as I am wasting a lot of IMR4227 from the 8" barrel, and the next fastest powders I have are Alliant Steel and Longshot. I did find the thread with load data for Longshot in the .222
I intend to use this both for small critter and IHMSA Half Size as well as just all around plinking.
Any analysis of the cast would be appreciated!
