retumbo powder

[sealevel]

is retumbo to slow burning for a 257 wbee.

h1000 is a good powder for the 257 wbee but I do not have any and non is avalible . Their is lots of retumbo and its only slightly slower then h1000....

One other option you may consider is the new Enduron 7977 , it is almost identical burn rate of H-1000 & seems to be available. Just a suggestion...

My current load for my .257 Bee contains a slightly over-book-max amount of Retumbo, and Berger 115 grain bullets. I can get 1" - 1.25" groups at 200 meters if I'm not too shaky. Bullet's moving 3315 fps at the muzzle.

I had the same problem finding H-1000 and switched to Retumbo

I use imr 7828, behind a 110 gr accubond. Never tried retumbo in mine

Have you tried VV N170 or N570?

Heavier for cartridge bullet should be fine, lighter bullet it may need something a tad faster.

Nothing written in stone , it could be the magic powder for your needs.

x2 on the 7828

I haven't tried retumbo, it may work well, but I suspect it's a bit slow burning and some of the stuff I've read online seems to indicate the same. Could be the magic one for you tho...

Used in in my 257 with 120 gr bullets. Great accuracy and vel
