UPDATE
Gentleman
I slugged the gun and this is what I found out: chamber throats are .432, barrel is .429.
Am I right to assume that bullets with a .432 diameter would be the way to go to increase accuracy and minimize leading or would the benefit only be marginal and i should stick to .431 bullets regarding the higher effort (commercially cast .432 bullets are not available in Germany, so I would have to make them on my own or find someone who casts them)?
What excatly happens when a bullet with a smaller diameter leaves the overbore chamber and enters the smaller bore barrel?
regards from Germany
Ulrich
