270 Win and StaBall 6.5

[Windknot]

I normally use stick powders in the 4350-4831 burn rate for the 270, but I have some StaBall 6.5 on hand, and I thought I'd give it a go. If anyone here has tried it and you might have some pointer I'd love to hear them.

This came off the internet.

Hodgdon has the tables on their site

IMHO, the 270 case capacities are approaching the upper limits of this powder.

I've never been able to get more than a couple of pounds to check out loads for in my firearms and don't find it to be any better/worse than other powders with similar burn rates, other than it seems to need more to do the same thing.

I have been working on this powder. Seems decent. I don’t have the exact numbers handy however I can fit more Staball in than RL22, and I why I switched.

I had a load worked up with Berger 140 Classic Hunters and StaBALL 6.5, I'll check my notes but I'm pretty sure I had them loaded to 3.340" and using near-max data from the Hodgdon website. Was a bit slower than they were getting.

My cousin has been using it with great success in his 270. He said his gun isn't fussy on bullets, primers, brass or amount of powder. It shot well with all loads he tried. Its close to 4831 on the burn rate chart so ne reason it shouldn't work.

A word of caution, in my experience, when using StaBal 6.5 is that it spikes real quick when getting near max load. One grain can make a big difference. JME

You're right, in small cases, but with case capacities such as the 270 has, this isn't much of an issue and you will get plenty of warning.
