Experts Only: Accurate Powder 2230-C (2460)

Is it possible to use this powder for .270 WSM rounds? In the manual it does not specify, and powder is non existent to buy for these rounds. If I can get a detailed instruction on how to use if possible, or where to go to get the specifications on the powders burn rate and etc. to find out if its plausible or even worth to use. Thanks

2230-C/2460 is quite fast for use in .270 WSM.

Although it is possible to use the powder, I wouldn't bother with it.

Under a nominal 140gr bullet, you won't even get to 75% case fill in the 270WSM before you hit/pass Max pressure -- with either powder.

Not recommended for many many reasons.

I've worked up load data for rifles where it otherwise didn't exist. There are two things to think about here before I offer any advice. First, there are plenty of powders suitable for 270 WSM still available as well as primers. It may not be what you were using before, but it is out there. Something tells me you weren't using 2230C before either. Secondly, you are on your own as far as safety goes.

If you start way low, which you should, you will be able to track pressure rising as primers start to flatten out and eventually you get either sticky bolt or primer flow. Both of those are indicators that you have gone too far. The last time I created load data I backed off 15% at the first sign of sticky bolt and called that max. I'm not going to recommend a starting load and honestly if you don't have a cojones to pick one yourself then creating load data isn't for you.

Best of luck.

~70% case-fill loads with spherical powders is an invitation to significant hangfire.

I do not recommend it.

Not that there isn't a ridiculously easy way around that, using a filler, but there are plenty of cartridges that are fine using a less than filling ball powder.

This is one reason why I never use any ammo handloaded by someone else.

This is why I ask before even starting. I appreciate all the knowledge and possible recommendations of certain powders to use other than the one mentioned. This powder will stay with the rounds its intended for. Thanks

Fixed my first post. I have been reading too many 7mm WSM threads lately, apparently.

Powder valley has several powders listed- 4350, 4831, 100V,4000mr, r17 and a few others. All of these can produce a good load in the WSM. Id stay way from the fast ball powders, not good compatibility with the cartridge.

You could contact Western Powders and ask them for loading data. My guess is that they will tell you that 2230-C is too fast burning to be used in a case the size of the .270 WSM. That cartridge needs a much slower burning powder. Perhaps the best option would be to find someone willing to trade a slower powder for your 2230-C. Seems like there would be someone out there desperate for a .223/5.56 appropriate powder. If you found someone with some Accurate Data 86 Extruded (sold around the same time as 2230-C) you could be in business.
