.300 win, 212eldx, retumbo

[Backcountry_IDN]

Retumbo is a good powder but I've heard it can produce flyers and I seemed to have that issue when I tried it a few years back in a 65x284.

I'm building a 300wm chambered for the 215 Berger and want to use H1000 if at all possible.

Regarding brass, I recently purchased 3 new boxes of Nosler on Gunbroker. I know it's spendy but it's top shelf.

I had pretty good luck with my 6.5284 and retumbo. Just not the velo I wanted (2800 w/143)

I think I'll try retumbo and see since I have a ton of it, then I'm going to move on to h1000.

Really wanna be around the velo 3k mark if I can

I tried 79gr of Retumbo with 212 ELD-x and Fed 215 Primers and got velocities in the 2970 fps range but averaged a flyer every 5 or 6 shots. The rifle I used was a long action with a long throat and still with seating the bullets out (3.5 OAL) this was a very compressed load. Velocities were surprising but pressure didn't seem excessive. Other than the flyers, accuracy was good. Overall I don't like very compressed loads so I didn't try to sort out the flyer business and just went to another load.

Awesome. Thanks for that info. I'll see since it wont hurt. Ive got a few lbs of it. Id like to not be compressed as well if I can.

I use the same load and have not experienced flyers. It's a consistent .5MOA performer.

I have had very good results using 79 gr of Retumbo, producing about 75FPS more velocity before pressure signs compared to H1000 in my 300WM Mil Spec 700. Precision and ES is comparable betweeen the two powders.

You guys have me thinking I may give retumbo a try since I have enough to rum a couple of ladders and follow up groups on my 300wm. I'll still run a ladder with H1000 then pick the winner and look for an 8 pound can.

I've never run retumbo, just H1000 on heavies so no insight there. I do have plenty of experience with all different brands of brass for the win mag though. Hornady would be about last on my list. Right along with win, rem, fed. I'd run Sig long before those. ADG if you can find it!

Been a fan of h1000, though 78 grains of retumbo, 208 amax's federal brass and cci250 work awesome for my krieger 26 inch barrel, sub moa at 1km.
