[QUOTE="Roughwater, post: 1624710, member: 33915"] I've had good luck with 8133 in my 28 Nosler. Has been as accurate as Retumbo for me in the 28 but slightly slower burning. It is dirtier than Retumbo but I think it's meant to leave a residue. We have tried it in the 7mm magnum with good velocities and sometimes very good groups but other times just MOA groups but we haven't decided yet if it's the fault of the powder. It is bulky but I just tried it myself in a different 7 Rem mag with 26" barrel and got 3304 FPS (Magnetospeed) with 76.5 gn using a 143gn hammer hunter bullet (was using Winchester brass). Didn't see any bad signs of pressure but that was just a one round test so I could judge where to begin and maybe end a ladder test. I used a forester long stem funnel which helped keep the powder from coming up higher than the bottom of the neck. I already loaded up some cases to do a ladder test but the weather kept me in today but may try tomorrow. [ATTACH=full]132037[/ATTACH] [/QUOTE]
