Hi all! Im looking at a purchase of a 470 Capstick, I gathering info on this caliber. The rifle im looking at is a custom made on a Interarms Mark X action and a 20 in barrel with a fixed 2 in muzzle break. It weighs about 10 lbs (no scope or rings). Shorter barrel than you describe above so MV would be less for the same charge. If I were to keep the same 2250 ish fps it would still require more powder to get there. Not sure how a shorter barrel affects recoil but what im wondering is will it be a beast or a pussycat ???

The closed system recoil would be similar to either barrel length- The open system, ie after the bullet leaves the muzzle would depend on the effectiveness of the brake and the pressure curve of the powder. A slower burning powder will generally have greater recoil due to two factors: an increased amount of powder relative to the faster powders and a significant amount of pressure as the bullet leaves the muzzle resulting in the jet-propulsion effect. It is possible that you could have a pleasant rifle to shoot if you can achieve the velocity you want by using one of the faster powders- .

My Douglas barrel should ship out this week. Has a dual taper, the first one to fit the B&C CZ550 Magnum barrel channel, then a slower taper for more muzzle girth and weight.
We tried a 3D printed barrel with 3/8 dia. steel support rod but Douglas said was still too much flex on the duplicator, so they lathed it by hand.
Good folks there!
