You guys are fantastic and I apprec all ur knowledge and info!
Got kentucky -Perdersoli mfg- from cabellas - 50 cal. I think cabellas handbk in general calls for max of 80 gr pyro RS for .490 RB. I've been shooting 70 gr P (pistol) pyro - I know I shouldnt. However, u guys indicate capable of much higher loads, 100 -120gr RS etc
Does cabells and manufactures under-rate loads for lawsuits etc and we therefore actually can shoot larger loads than specs?

what is max load for pyro P and pyro RS w .490 roundball.
Would RB shoot significantly farther (at least 150 yds) with RS vs P even by increasing loads proportionately? THANKS!
