(1) The Foster slugs have very shallow rifling and since these slugs obturate in shotgun bores, most of these grooves are ironed out in the process.(2) S & Ws gain-twist rifling should help conventionally constructed bullets, and reduce throat wear.(3) All guns still have the mirror-smooth polygonal rifling that produces such fine accuracy with jacketed bullets.(4) he could clearly see the rifling of the bore(5) All were loaded with the bullet seated .010-inch off the rifling , in Winchester cases with CCI large rifle magnum primers.(6) To rectify the problem, the Enfield form of rifling based on five grooves and lands is introduced, so the last of the British military Martinis are called Martini-Enfields.(7) One type is a round chrome moly steel liner that is button rifled to produce an ultra-smooth bore with uniform rifling .(8) There's no rifling in the barrel, and you call it a rifle?(9) In their six grooves, Colerain barrels feature round bottom rifling that holds less fowling; square bottomed grooves reportedly retain more fowling.(10) This is interesting as this type of rifling generally yields poor results with cast lead-alloy bullets unless they are gas-checked or very hard.(11) There is some conventional wisdom that says, for varmint rifles, simply seat the bullet to touch the rifling .(12) Inspection of the bore revealed the near absence of rifling .(13) The rifling of the barrel is polygonal with a 1: 19 twist.(14) The barrel can be rifled and this rifling causes the projectile to spin, increasing its accuracy.(15) The new tapering projectiles could be directed with greater accuracy when rifling was introduced in artillery barrels.(16) I would have bet that the conventional rifling of the Douglas barrel would have been more accurate.
