Powder - H50BMG

After getting frustrated about finding powder, I decided to see "just what is in stock at Midway" and work from there.

- Black powder substitutes
- H50BMG

I guess this means I either need to buy a 50, or figure out how to load with that stuff, even if it is sub optimal for the application.

I know that this is overly simplistic, but it seems like it is optimized for loads that want to push "light for caliber" bullets at around 3 000 + fps.

Does that sound like a place to start looking for loads ?

This prolly ought to be in the reloading sub forum, but I'll give you a shot out anyway.

I've loaded some of the offerings for the 50 cal (incidentally not h50 BMG) and they can be loaded in calibers such as the 7rum, 300rum, 7mmstw, etc..
You need a rather overbore round with a rather heavy bullet to make the offerings for the 50 Browning work well. I've used rl50, wc872, I5010, aa8700... probably a couple of others too...

You have that backwards, you will be looking at heavy for caliber bullets at lower speeds if you can make it work.

Yes, you are right, I posted this in the wrong sub forum- sorry about that.

I guess my thinking was guided by seeing it used on 200 grain bullets in a 30-378, but you are right, 200 grains is not a "light" bullet for a 308 size.

Re: Powder - H50BMG

Even in a 300 RUM pushing the 240 SMK, I could not pack enough 50BMG in the case to get decent velocities and certainly would come no where to seeing pressure. On the flip side, it had great ES, good accuracy and is known, in general, to be highly temp insenstive.

200g bullets, in terms of what is often used for long range hunting, is not heavy. My point is, even with true heavy for caliber bullets in big cases, H50BMG is often too slow of a powder to get expected velocities or velocities that can be had with faster powders, such as Retumbo or H1000.
