[QUOTE="Master Carper, post: 2249129, member: 15527"] The "problem" with most T/C Pro Hunter barrels is the "flex" from its longer 28" barrel. I did a series of tests with these barrels, shooting before and after groups and every barrel that I cut from 28" down to 23", accuracy was cut in half. Meaning, that if one gun grouped 2" at 100 yds., after cutting is back to 23", groups averaged 1". One gun shot 1 1/2" groups and after cutting the barrel, it then started shooting 3/4" groups. All rifles tested performed this way... Also, with most factory barrels, depending on caliber, you would expect to see a velocity loss of 100-200 fps. but, velocity loss with cartridges like the 22-250, 25-06, 7 mag. and 300 Win. Mag. averaged 20-35 fps. from those barrels going from 28" down to 23"... Another reason for the accuracy issues and minimal velocity loss, is that the last couple of inches of bore in these 28" barrels, is that the bore and groove diameter is badly oversize. In other words, there is a "swell" in the bore and by removing this, the barrels vibrations and harmonics change as well as gets rid of the internal oversize part of barrel... I'll post a link to the tests that I did if anyone has any interest in it.... DAVID [/QUOTE]
