[QUOTE="AZShooter, post: 1152004, member: 5219"] Two ideas and one will cost nothing. 1)Why not seat to fit and feed from magazine with the 215s and see how they perform? My experiences with the hybrids has been excellent regardless of jump to lands. You may have read that a short seated bullet will impinge on the powder capacity of the cartridge causing it to loose velocity. IMO you will not loose enough velocity/performance to matter with a deeply seated bullet. For grins measure the powder volume for the current COAL vs the intended longer COAL. Turn the difference into a percentage then divide by 4 to get the approximate velocity change. 2) Call Wyatts and talk to them. I am certain they can tell you which system would work best. The machining involved in making an extended magazine box fit and altering the bolt stop is not a big deal. Heck I fit a longer box to a SA rem with a dremel tool! [/QUOTE]
