Forgive me if I haven't been paying attention , but what are the 231 loads for Missouri 200 gr SWC's that will not load up the barrel and will stack up ? Are these the target bullets I should pursue ? Currently shooting Montana gold 230 CMJ's @ 6 gr's of 231 . Great groups and easy cleanup .

6 grs of 231 is pretty hot for a 200 gr bullet. I imagine it's extreme for a 230 gr.

5.7 grs of 231 will just make power factor for me.

Are you concerned about making major PF?

No , I've just been poking holes in paper . I should probably dig out the chrono and see how fast the 230 gr ball I shoot now is going .

5.0 gr of 231 with 200 gr lead bullet is super gentle and accurate, approx 730 fps...

5.7 gr will get you about 830 fps...
Thank you for the info . I had read that too fast will lead your barrel and too slow will also . It's been a long time since I've loaded or shot lead so I'll have to get back up to speed .

Bill , I just got done shooting the 230 cmj's over the chrono . These are the 6.0 gr W231 loads and they averaged 765 fps . These loads came out of the Speer #12 manual and the top load for 230 gr cmj's is 6.2 grs of W231 .I haven't done ANY load testing as far as raising and lowering powder charge . When I loaded these up and shot them from a rest they worked well and I got stuck in a rut . I just received the 200 gr SWC's from Missouri bullets today so perhaps I'll put a little more effort into working up a load for these .

I don't use Win 231 anymore, but when I did, for target price my load was 4.1 gr of 231 under a 200 gr LSWC-BB with a .928" to the shoulder and .468" crimp

I bought some Mo. Bullet Co. 200gr. SWCs while travelling in (where else??) Mo. last month. They were labled IDP #1 brinell 18. Very nice bullets. Have loaded 5.4grs 0f 231 since forever, it seems. With 200 gr SWCs the load is running just below major and has been my practice load for a long time. It's a bit (just a small bit) easier on the gun than 5.6grs which will make major in most of my guns. May not make a great difference but I do it anyway.

That seems a tad slow, as my 230 gr Sierra FMJs make 735 fps with but 5.1 gr of 231 from both my 4.5" M&P and 5" Para P14....was your tesing in 15-20 deg F weather? (if so, that would make more sense to me)

Do you have any chrono data for that load?

I've used as little as 4.2 gr. of w-231, still had an accurate load.
BTW that was w/ 200 gr. RNFP's, will work w/ SWC's also.
My gun seems more reliable w/ an OAL of 1.270" w/ SWC's.:)

For 200gr loads I use 5.1grs of W231 or 4.5grs of Red Dot. Both give soft recoil and also great accuracy up to 75ft.

I like to stay mid range in all my target loads to avoid leading.

I get about 6200 rounds out of a 4 pound jug of Red Dot that cost $53.00.
