Retumbo Powder

[Boyd Heaton]

Have been testing it in my Light 300 Rum with the 220 MK...It is a Large stick powder.Larger than Rl25 H1000 and H4831.But it still run's through my RCBS powder spitter pretty good.I have seen velocity increases of about 55fps over the RL25 before thing's get alittle sticky

..Accuracy is as good as the 25 in my gun....Am gonna shoot it at Willimsport this Weekend....Will keep everybody posted.........

Try Norma MRP-2. MRP2 is first run RL25, original mftr lots go to Norma first, and they test. Norma take top lots and remainder is sold to Alliant who sells them as RL25 and RL22. MRP is first run RL22.

I am very pleased with the Retumbo.I had 9 in 8.5 inch's.And a blown peice of brass took me out to 13".Time for new brass I think.........

Hey BH, I didn't know about the Norma powder. Hope to be able to find some in this area!
