[QUOTE="JeffVN, post: 455520, member: 2261"] I have more then one 7WSM, and they all run the berger 180s at or over 2,900 fps. One rifle is a Surgeon short action and depending upon the barrel that I have installed, uses an AI 308 length magazine or is single fed. She will run 2,900+ from a magaizine and a 26" tube when loaded to 2.90," with the Berger 180s, but that is a stout load of RL-25 or H4831SC in my rifle. When single fed with a long-throated reamer and OALs over 3.25" she gets to 2,900+ with the Berger 180s at close to nominal pressures with RL-25, H1000, H4831SC. My other rfile is an F-Class single shot Barnard action and 30" tube, throated to seat teh berger 180s way out...OAL over 3.2." I prefer the Long action approach to the world if you need 2,900 fps on teh Berger 180. Its easer to set up the freebore that you want and get to 2,900+ fps. JeffVN [/QUOTE]
