300 Rum. powder
I have reloaded my 300 rum. with RL. 25, and have not tried any other brand's. I was just wondering what brand's of powder you guy's are using and why. Thank's: Rick.

Retumbo has worked the best for my brothers 300 ultra it will shoot 165gr sst and 180gr barnes TSX into a ragged 1/2-3/4 hole. we use 100grs of powder but start lower than that and watch for pressure. We also have alot of bullit jump its like .175 jump but it shoots great. I think you will love retumbo in your 300 ultra.

91.0 grains of RL-22 behind a 180 grain bullet....thats the ticket.

I put 98gr of H-1000 behind a 168gr CT Ballistic Silver Tip. One hole groups at 100 yds. Also i use the same load with 168gr Barnes TSX with similar results.

RL25 and H1000 are good but I've found the best results in my 300 Rum were with Retumbo as well. all my testing was with 180 & 200 gr bullets

AR2225 (Retumbo) is great with the 200 gr NOS AB's

I got an email from Ty Herring of Barnes customer service and from the data, for a 200gr TSX,max load of 105gr AA8700 vel. 2919 fps,load density 99% should steal the show and save the day!It was more accurate than Retumbo and R25 in the tests.
