55gr. in 6MM

Scott5 · August 17, 2008, 06:16 PM

Hello all,
I'm thinking I need to use up my pound of H-322 and the 6MM is the perfect rifle to use it in.

I have a bunch of 55gr. bullets to load up but the only data is for the 60gr. bullet,
http://stevespages.com/243_7_60.html.

So I think I will start low and work up in one grain increments until I get to the top for the 60gr. then see how it goes.

If any of you have used this combination before let me know you yours went.

Happy shooting

Trying to extrapolate the use of a powder used in the a 60gr bullet to use a 55gr bullet in the 6mmRem is not ideal.

I have checked data from Nosler, Hornady and Hodgdon and can find no references for H322 in any 6mmRem bullet weight. I have no way to document the listings in Steve's pages with any recent loading manual.

I personally would not use that powder in the 6mm.

Per Shoney, I'd go with a slower powder!

H322 works great in 223, but I would avoid using it in a 6mm. It is about the same speed as Reloder7 or IMR4198, so it would work great for 223 for light bullet loads. For 55 gr bullets in the 6mm, try Varget, IMR3031, or IMR4320.

I think what everybody here has danced around is that you'll end up with far less than 80% loading density and you'll end up with erratic ignition and pressures. What may seem like a safe load can cause major spikes in pressure and you could be wearing that rifle. I wouldn't suggest using it. Try a slower powder. FWIW, Steves pages do not show that powder with the 55's.

Scott5, rather than risk damage to your weapon or yourself, you might want to consider using the remaining powder in another more suited caliber or trade it to someone for something else you can use. Taking such a gamble on even a full $18+ cannister of powder is not worth the potential disaster that might occur.

Thanks everbody for your replys.
I think I will use another powder for my 55, 58, 60, and 65gr. in my 6mm Remington.
I haven't decided what to use on them yet, but I will be loading them up this weekend to shoot next weekend as my rang is having a Cowboy shoot this weekend.

Happy shooting
