Is anyone using Retumbo.

[1Shot]

I have a 264 Win Mag with a 27 3/4 inch barrel and was wondering how Retumbo would work in it. Is anyone using Retumbo in a 264 mag?

Can't answer on the 264 but I can tell you retumbo worked a miracle for me in a very fussy 300 wby ultralight. It wouldn't shoot 2 moa with anything and now shoots under 1moa with both the 200 ab and the 180 tsx.
What I can say is that it is ever so slightly slower than h1000. So if H1000 is viable for the 264 I would say you'll get a grain or two more retumbo to get the same speed.
I can also say that it seemed pretty temp insensitive in that fussy 300 wby.

I used RL 25 with my 264 Sendero to realize 3400 fps with 120 grain BT's. I suspect retumbo should do as well or better.

I started using Retumbo this past summer in my 338 RUM. Great powder!

Retumbo is my favorite powder for my 7mm Rem Mag and my 25-06. I also used it for my 300 Win Mag when I owned one. It is the most accurate powder I've found in the aforementioned cartridges.

Thank U-all for your reply. I bought a pound of Retumbo today and man it looks like #2 pencil lead chopped up. I am going to try it with 120 Nosler BT's and some Hornady 140 SST's and Spitzers as soon as it quits raining and the wind blowing 25 to 35 mph. I have a 25-06 with a 26 inch barrel that I might just have to give it a try in also.

Retumbo was a nice surprise when I first tried 150gr bullets in the 270WSM. Decent velocity just over 3000fps, low low ES, and very tiny groups that made me look like a good shot. I just didn't stick with that load once I discovered the 140gr AccuBond and Magpro.

I do know that Retumbo is a favorite amongst the 6.5WSM and 6.5SAUM shooters. It should be a dream in the .264WM!

The powder of choice for my 338 Lapua Improved. Only thing I don't like about it was it burn kind of dirty, and it takes some scrubbing to get it out of the barrel. Other than that, my 338 loves it.

Here' the result!

AT 100 yards - 3 shot group

At 510 yards - 3 shot group

At 535 yards on my metal gong - 3 shot group

I started using Reumbo in my 7mm RUM with 160 AB & Fed. Match Mag. primer. I couldn't get past 92 gr. without sticking cases & velocities & groups were ho hum :? Tried US869. Groups were better but velocities were just over 3300. Then along came H50BMG Velocity averages 3450 & groups are 1/2 inch or better, on a good day :grin: I also tried Retumbo in my brother-in-laws 7mm Mag & it shoots pretty good with a 160 NP.

If I shot canister powder in my STW, Retumbo, and H50BMG would the two powders I would start with.

 

[bobbyrum]

Antelope_Sniper, US869 may also be worth a try

 

[Antelope_Sniper]

Yes, 869 would also be worth a try. I still have most of a keg of WC868 that is also proving to be a nice stw powder.

I forgot ot add that 106 grains of retumbo drives the 200 grain AccuBond at 3270 fps from my 30-378. This is a 200 yards group, .8"!
