[QUOTE="Fiftydriver, post: 2705074, member: 10"] Most modern cut rifled barrels are pretty close to advertised numbers. Button pulled barrels will often be slightly slower twist then advertised simply because of the manufacturing process. in my experience a button pulled barrel will be around 0.2” slower then advertised twist rate. when i started building my wildcat rifles for the public, we needed some custom barrels for the very heavy and long bullets we were using. was using a button pulled barrel manufacturer and had to order custom twist barrels for these new bullet designs. Since i had to pay for these custom BUTTONS i ordered them 1/4” faster twist then i wanted the end pitch to be, as such, they arrived for the most part dead on for twist rate. as mentioned cut rifled barrels are usually dead on. Hammer forged barrels are also very close to the mandrel used to make the barrel. Now if the mandrel is actual accurate to whats advertised, hard to say…. i generally only use cut rifled barrels for these reasons. Also, i can get rifling to any pitch i want, usually without an additional cost, not possible with button pulled barrels. [/QUOTE]
