Even the Nosler 300gr JHP (part# 42069) has a diameter of .429". Same thing goes for the Henry 357 Mag rifle. It's bore is bigger than the Nosler bullet.

fast forward to today .... I've completely lost track of how many round have been fired from though our 44 since April 7th .... what I can say without any doubt it has been thousands, if not something over 10,000 .... all have been hunting level loads pushing Nosler 240 gr JHP .... this afternoon after removing the large lever, the bolt and the ejector, I thoroughly inspected and cleaned the rifle ....
1. no observable sign of copper buildup in the barrel
2. chamber wasn't as dirty as anticipated
3. 3 screws had worked loose
a cleaning patch soaked with Sweets 7.62 Solvent confirmed, no copper buildup .... Ballistol soaked patches took care of burnt powder residue .... blue Loctite should take care of the loose screws .... no ejection issues .... new inner and outer magazine tubes seem to lockup as designed .... I tend to believe Rugerfanboy is correct .... all in all, I can't help but be pleased
