HELLO and THANKYOU DAVE@IAN, gents let me tell you about my progect and if there is any glareing problems you can maybe give me a heads up -ruger#1 action ss.32"mic barrel{local builder} 1.25"-1/10twst ss,the barrell@ action will be sleaved to support weight of barrel and replace the forearm the rear laminated stock will be fit with an adj cheekand 3way but assy,I ordered a match spec reamer from DAVE KIFF at pacific percision Ihave a throater already -the fact that the ruger is a single shot falling block oal of the case isnt going to be a problem and as IAN says the throat will have be set up so as to have a 240mk's boattail start at the neck shoulder datum so as to save case capacity for powder-hopefully I can obtain vellocities with accuracey around 2800"or better , now let me state right up front this is what I would like to happen weather it is cappable is the question-and the reason i ask more experienced shooters for their oppinions and sage wisdom . ultimately the idea was to see weather the 300wsm could compete against a 6.5-284{142}/6.5-O6{142}/6MMBR{107} all loaded to the potential of my guns I compete in Fclass competions{B.C CHAMP}and going thru the process of picking the calliber I will shoot in the upcomeing world chamoinships-now i know there are plenty of boomer cartriges out ther that can surpass the ballistics of the callibers i have mentioned but there are also certain constraints that limit there use for instance NO muzzel brakes,22# weight limit with scope and front rest a safety template on the range -nothing bigger then 8mm or faster then 3000"{double checking those figures} plus you have to be able to take the recoil for aprox 45/60 shots per day for three days {not includeing practice prior to the macth}the world champs will be shot in ottawa next august and will be fired at 700.800.900 meters 900 being shot twice with 20 shots on score each time with time limits at all ranges if there is another cartridge i should look at please let me know
thank you
