shanehamblin Report post Posted December 28, 2014 Hey guys I've got a buddy that just picked up a 25-300rum. He hasn't been able to find any load info on it. Any load info or cartridge information it'd be appreciated. Thanks Share this post Link to post Share on other sites
firstcoueswas80 Report post Posted December 28, 2014 25/300 RUM? Holy crap... never heard of that. Id think rl 25 & 33, possibly h1000 & us 869 would be your friend... for about 500 rounds before it's time for a new barrel. 1 Share this post Link to post Share on other sites
shanehamblin Report post Posted December 28, 2014 I guess my question is an it might be a stupid question cuz I myself don't reload. Will the min-max loads be the same as if we were loading for a 300 rum? Share this post Link to post Share on other sites

HuntHarder Report post Posted December 29, 2014 lighter bullets take more powder to push them. I know it sounds opposite of what you would think. I would look at some 7rum load data, and try to go from there. Maybe look at difference from 300 rum to 7rum and go from there Share this post Link to post Share on other sites
Couzer Report post Posted December 29, 2014 Maybe look at the 257 Hot Tamale? This is built from the STW I think Share this post Link to post Share on other sites
308Nut Report post Posted December 29, 2014 Yawzer that's a hot cartridge. I'm thinking minimum RL25 but 33 and RL50 are probably more appropriate as is H50BMG. That much powder down that small of a hole will need the slowest possible powder. I hate to be the kill joy of the bunch but I think 500 rounds of good consistent barrel performance is a bit optimistic. It'll be fun and cool for sure though!
