My latest Mashburn Super, designed to be a walking gun, is a 1970's Rem 700 in 7 MM Rem punched out with 24" tube. I replaced the stock with a Brown pounder and X coil sporting clays pad. Glass is 6x33 Lupy with LR dots in Talleys. Weight is just at 7.4 lbs and calculated recoil 33 ft.lbs. I am currently doing load development and am at 73 gr. H1000 giving 2950 fps. with 175 Sierra's. Target is 3075 or so and will swap Sierras with Nosler PT when necessary. COL in this gun is 3.6" This gun is designed to be slightly weight forward.
My other Mashburn, a blind gun, started life as a Brown Precesion 7 MM Rem 24" punched out with 2.5x10 Swarvo Habitch at about 8.25 lbs. I shoot 162 gr Hornady BTSP Interlocks at 3269 fps. using 76 gr. RL-25 and get groups of .6" When sighted in 3" high at 100 it is on at 315 yds. or so. COL here is 3.56" Both COL's are bullet to the base of the neck.
