I reloaded 8 rounds of 230 gr Rainier over misc used brass, Fed Lg pistol primers and 5.1 grains W231.

All 8 rounds fired, no malfunctions. Phew!!

My OAL is 1.265

My crimp is about .474" Just a tad narrower than the width at the lower part of the brass.

Question: I have no idea how fast the round is going, but it seemed very mild. (4.25" barrel)

Should I up the charge a bit? I'm trying for about a power factor of 165-170.

Before firing the rounds, I dropped each round in my barrel ( I took the gun apart) to make sure the headspacing was OK. I could hear a distinctive "click" as the mouth of the round seated against the headspace in the barrel.

Also the rim of the catridge seemed flush with the barrel hood, like my other commercial rounds.

Pretty exciting to have all my rounds go off OK :)

Sounds good. One suggestion--change the diameter of your crimp to .470. This will give optimum bullet pull, and will make the round much more efficient.

You will also notice that as you tighten your crimp, the velocity of the round will increase, and the results will be more consistent down range.

5.1 grains for this bullet seems like a good starting load, and falls well below the starting range for 230 grain jacketed bullets in Speer #13. Have you chronographed the load? May be interesting.

I use about the same load, but crimp to .471

I use Berry's 230grn rn with
mixed brass
Winchester large primers
OAL 1.265--down to 1.260

5.1 gr Win 231

I get velocities avg. out of my Dan Wesson 5" of about 740 FPS.

My Power factor at the last match was 171.

So it depends on what you want the round used for on how fast you want to push it, why hurt yourself with recoil if all your doing is target shooting??

If you want to target shoot or steel I would suggest around 4.8 grs of 231.. talk about powder puffs. :)

If your looking for accuracy then your going to be shooting some till you find what your weapon really likes.

In checking the Winchester reloading guide, their starting load for 230g fmj with W231 is 4.9 grains yielding about 695fps.

The max shown is 5.7 grains giving 830fps.

I have never loaded plated bullets such as Raniers, but I would not hesitate to use fmj data and work up from the starting loads.

It sounds like you are on the right track with what you are doing.
Above all, be conservative (and safe!) when starting out.

The 45 ACP is about as easy as it gets for reloading.

Good Luck Chief!

WOW! Thanks for all the input.
I'm assuming that I'm "theoretically" over the 165 power factor with 5.1 gr W231 and 230gr TMJ.

Of course I have a 4.25 CDR length barrel, so I do need to chrono the loads. I friend of mine has one, so maybe sooner or later I'll check 'em out.

I'll tighten up my crimp just a tad like suggested. I think it's barely at the minimum too. I found it fairly easy to adjust the dies, so it won't be a big deal.

Nice to see other Navy folk on the forum- even if they aren't AG's ;)

Take care,

BTW-
Is there a ballpark figure for the velocity loss going from a 5" to a 4.25"?

I notice most quote velocities with the 5 inch barrel and I wondered how much of a loss I'll see with a CDR barrel,
I'm thinking about 2-3%??

Thanks!

The Sierra manual recommends a .473 crimp...

I've read lots of things on the Brian Enos forum and Matt Burketts about over crimping really hurting accuracy.

Is there anything published on this?

IIRC, some time ago, I saw something published showing a velocity loss of approximately 50-75 fps in the 4.25" Commander barrel.

You are probably in the 165-170 ballpark now.

Obviously the only way to know for sure is to chrono your loads since each barrel behaves quite differently.

Thanks Berkim, I remembered that when reviewing the Dillon video again. I verified that with some of my reloading manuals too--

MAG,

You speak "weather" too? :)

I'm gonna call my buddy and borrow his chrono as soon as I can get to it. In reality I'm not too worried about the speeds, but just more interested in being in the ballpark.

Thanks for the good tips.

Plated bullets

MAG-63, from everything i've been told "Plated" bullets such as Rainer and Berry's should follow more along the lines of Cast Lead bullets the "jacketed" bullets.

I do agree though that 4.9 up to 5.6 would most likely be fine with win 231 with the Rainer bullet.

GO NAVY !.. LOL..

Hunterjbb,

Thanks for clearing that up and " a lernin" me something new.

Just another reason that this is the best forum of it's kind.

Ranier/Berry's bullets seem like a very good buy even when compared to cast.

I'll have to try them.

Thanks again!
