pretty hot load but I cant stop shooting it when the first three go into one hole. After the first three it starts to open up a bit, but its a flimsy tube. Start at 90grns.
I loaded a few in a factory Rem and by 89gr of Retumbo showed strong pressure signs, a guy needs to start lower than 90gr!!!

I'll wager the cases will not hold a primer after the second fireing of 94 grains of Retumbo.....Depending on the lot of course.
I had to back off to 93 grains with the 300 bergers and not jam the lands to get the cases to last in a long throated (3.998) Edge.

Re: 338 Uttra mag average velosity

Running the 338 RUM at a restricted OAL (AI Mag length), I had serious pressure signs @ 92.5grns of Retumbo with the 300 Sierra. Lost those two cases, didn't pop the primers, but while seating the new primers, they wouldn't stay in the case!! Start in the 86-88grn range just to be safe.

My load right now is 90.0 (yes ninety) of Retumbo

FED215M
Rem Brass
300 Sierra

5-Shot average of 2780FPS w/26in tube

Re: 338 Uttra mag average velosity

I have the same gun except put a B&C stock and rifle basix along with a de brake. Im only shooting the sieera 250 bt sptz getting nice 3 shot groups. I was actually a .318 the rest 900 and in the 6's. Im shooting 96 grsins of H-1000 kind of afraid to try the 300's. Having chronograph issues anyone guess what i might be getting from that load out of a factory 26" ?
