Bore diameter of Winchester 25-20's|Winchester Rifles|Forum|Winchester Collector

Hey guys I did not know where to post this so here goes. I will assume that most of you that shoot the little 25-20 reload your own bullets. So my question is what is the average bore diameter of your rifles when you slug them? I am looking at Lyman 2-Cavity Bullet Mold #257420 25 Caliber (258 Diameter) 65 Grain Flat Nose Gas Check. Just wondering if anyone has any suggestions. I do not want to buy pre-made bullets.

Forgot to add that this will be out of a Winchester 1892 in 25-20

Thanks

Steve
