Need a 9mm 138 grn Win231 recipe

BCCanuck · October 19, 2009, 10:22 PM

First, I am new to your website and have found it to be quite good. Thank you to everyone who offers info.
I have lots of Win231 that worked great with 9mm Frontier CMJ 115 grn RN bullets. Now I have some 138 grn Frontier CMJ RN bullets and cant find a loading recipe. I contacted Frontier who said the 138 grn bullets were discontinued and they now make 135 grn bullets instead due to higher demand. They said the 138 grn bullets should work just as well.
My question is whether the 3 grain increase in bullet weight will make much difference and how much should I reduce the powder because of the additional 3 grains.
Where is a good place to start for developing a load using WIN231 powder?
My book doesnt have a listing for 135 grain plated bullets using WIN231.

Welcome to the forum. I think you'll like it here.

See if this helps any.

Just select your 'load type' and 'cartridge', then hit 'get data'. The 138 isn't listed, but it's a starting point with 231.

Start with the 147 grain loads and work your way up from there.

In answer to your question.
No.
3 grains in bullet weight is not enough to worry about.
My cast bullets vary in weight during the same casting session. Just start 10% below the max charge and work your way up looking for signs of too much pressure. WW 231 is an excellent powder. That's what I use in my .380 9mm and 45acp.

I used to buy bullets from a supplier that his jacketed bullets would vary buy 3, 4, 5, grains. They shot well. don't worry. shootem
