[QUOTE="älg, post: 263456, member: 2995"] Re barrel burners .- <I think one can get a very general but fair idea for comparisons if dividing powder grains/caliber. i.e. 90 grains/ 7 mm cartridge: 12,86 65 grains/ 7mm cartridge: 9,28 It does not give absolute figures but I thin k can be an easy rule of thumb for a fast comparison. Of course it does not bear in mind bearing surface, speed, etc.. but does the job. Re. the 7rm- it is well behind the 7rum but even being an oldie I would not treat it as useless. There´s many swearing for the 7wsm now and the 7rm is equally if nor more capable. [/QUOTE]
