[QUOTE="milo-2, post: 2556513, member: 33622"] I have read a good portion of the pitch, left gain tw ranks right up with canned beer and sliced bread. The laws of physics don't seem to apply to left tw, and adding gain is gooder. I have been shooting a left tw 7 saum barrel for yrs, and if the majority of your rifles are right tw, you better remember the difference if you touch a shot off at distance. I also shoot a left gain twist 6x47 Lapua, I wait for the magic. Most left gain tw out are 6mm, small cases, being fired with relatively fast powders, so I am lost on the soft start, and the subsequent velocity gains. If all the powder is burned in a short secction of the barrel as stated, does that area become a hard carbon buildup area? Of course, it is an accurate barrel, or it would be in the scrap pile, but so has every other 6mm barrel I have had spun up. I also shoot a right gain 6 BRA, extremely accurate, my speed seems high, 105 hybrid at 2900, 26" barrel. Is it the gain, or just the barrel, because my charge weight is not out of order, just faster. There are names that could sell a 20 grove barrel, as we saw around 6 yrs ago with bore rider throats, I guess gain tw has survived longer, lol [/QUOTE]
