Cylinder reaming question

[kelbro]

May be a strange question but could reaming cylinders out to shoot cast possibly make any difference in how jacketed bullets shoot?

Never concerned myself with it before as my two SAs only shoot cast and they have roomy cylinders. I have recently acquired an SRH 45/454 that shoots jacketed very well but I want to shoot cast in it and the cylinders are just barely over .451.

Try sizing your cast bullets to .451 before changing the cylinder. Slug your bore and see what it is first.

Should have mentioned that I have not slugged the bore yet. Plan to sdo that this weekend.

I have read a lot about reaming cylinders in 45's, but nothing about smaller calibers. Anybody do this with 357's etc, or are they usually good as is? I just slugged the bore on a new to me Blackhawk 357, then found the slug drops freely through the cylinder bores so I think I am good.

What method did you use to measure? Every SRH 454 I've run across (or had people measure for me) where usually close to actually being .454"

It's a waste of time to slug the bore. Slug the CHAMBERS. Size bullets to chamber mouth diameters.

I 'waste' 3 minutes on every gun I own to know what the bore is and to check for thread restriction.

Well, it's a non-issue for this pistol. I just re-slugged the cylinder and they all measure .4525-.4528. Not sure how I messed up before. Maybe morning eyes vs. evening eyes reading the mic :)

Shoot the gun with the cast bullets first as this CANNOT be predicted. My tight Ruger 3-screw 45's shoot .454" SWC/RFN bullets very well indeed.

Mold is on its way. Jacketed gets expensive in this pistol. It likes to be shot a lot!
