For those of you with the newer Winchester (Miroku) 1873 rifles in .44 wcf, I'm wondering what your barrel diameters have measured out as and what diameter of case bullets have you had best results with.
I've been shooting several 92s and a Colt SAA for years but have a hankering to try an 1873. The RCBS 200 grain .44 slug, sized to .428 has worked well for me in my current guns, almost exclusively over Unique powder. I believe my SAA would allow .429 bullets in Winchester brass but I would feel better with some actual feedback from those shooting the newer Miroku rifles.
My preference would be for a straight gripped, 24" half round model although I know of a full oct one for sale nearby that is gently used.
Thanks for any personal feedback and recommendations.
