[QUOTE="gnbruce, post: 1926083, member: 103951"] the throat .250 with a bore rider finish cut (other wise 20n29 was about 90% fill rate). With the bore rider we gained 8 grains more powder and 120 ft/sec . We started with the 7 twist and the 240 lazers at 3200 gave us oblong holes at 100 yrds , improved when we took them to 3400 ( over pressure) went to 6 twist works great I think a 6.5 twist would do it.
