[QUOTE="brianwinzor, post: 91176, member: 1067"] Kirby, 224AM looks good, and really looking forward to the test results. I know it is a trivial matter, but I believe that you might have made a "typo" on the case capacities. Should it be 77.2 for the 22/270WSM and 82.5 for the 224AM? Chuck Hawks lists the 270 WSM as 78.9, and the Short Mag website lists the 270 WSM as 82.0 grains. Regarding the best powder for the 100 and 107 grain bullets, if my previous experiences with the .224 Clark (63.8 grains)are of any benefit, then my guess is that WC872 will be the best powder, unless the soon to be released H869 proves to be slower than the old H870. I have never used a "Short Mag Case, but out of curiosity, is there a general consensus as to how much body taper is necessary with the WSM and RSAUM cases, for them to feed well from the magazine. I note the standard .270 WSM has .017 body taper in its 2.100 inch length, but have not read anywhere how much you can reduce that standard taper before encountering magazine feed problems. It appears that anything less than about .010 body taper in a 2.500 inch case leads to feed problems. Looking forward to that first test report. Brian. [/QUOTE]
