Does anyone have any reloading info on a 6.5x300wby? Looking for powder charges on a 140gr ELDX.

Powder charges on something like, ehh just half the bottle oughta work.

I would call Weatherby & Hornady and see what they have to say.

Gonna need a slow powder. Maybe R22 or H1000. Might need slower than that though. I run both of those powders in 7mag and 300wm with good results

Slower is better.H1000 RL25.

Retumbo or US869 would probly be in the line you need.

US869 gets my vote. My 26&28 nosler locked in on these powders big time.

Sounds like a couple of good ones to start with. Prefer the Retumbo for temperature stability. With that much case capacity behind a small hole, very slow powders are probably the best bet for this fire breather.

Don't have a load for that bullet but powders I'd try are:

N570, RL33, RL50, 50bmg and H870.

Those should get you over 3300 fps. The afore mentioned stuff is good for about 3250.

Imr7828 is a good slow burning powder.

The IMR 7828 is a good slow burning powder..have used it in the 300 RUM for years and should work well in the 6.5

7828ssc check out reloadersnest.com good info there.

I bet barrel life will be less than 700 rounds, maybe even less than 500.
