twist rates

[odis]

I have a question regarding the twist rate of my 45 colt revolver. It is 1 in 20 6.5" and the gun is a BFR Prec Cen. I was wondering what the experts feel would be the optimal weight for this combination and whether I should go with a gas check or plain based mold. I would like to try 325 grs but I don't know if the twist rate would be compatible with a slug that heavy. I'll be buying my mold from Accurate Molds LLC.

20 twist is easily fast enough for a 350 grainer 452 diameter boolit. ... felix

Thank you Felix, what are your feelings about gas check versus plain base? This revolver will be my primary hunting arm during deer season and I shoot other guns for recreation.

Been shooting a 32" twist in my 45, up 360 grain Keith bullets are wonderfully accurate

don't be afraid to ask Tom he will answer all your questions and is quite knowledgeable. Hs customer service is excellent

If it mostly a hunting gun i would go with the gas check. (Got my flame suit on)
As a hunting revolver you want ever bit of accuracy you can get.loads will be easier to work up and you will spend less time jocking with alloys,hardness and to some extent size. Just a eassier world to function in.

Dwight Hardy makes a good point.

Personally, I don't hunt, I cast, load and shoot for my hobby. I do have a pair of .45 Colt Blackhawks, two GC moulds, and three plain base. I seldom use a GC. You might not shoot enough for the cost of 2 or 3 cents per GC to be an issue. I don't use them b/c of the cost and the time to install them. I typically cast about 400 to 500 at a time and don't want to fool with the GCs. I prefer fooling with the loads, alloys, dimensions.

You're not going to loose either way you choose. Also it probably won't be your last mould. You just need one to start with.

For a hunter, I'll vote with Dwight. Start with the GC.

Thanks for the responses, I feel that Tom has a bullet that will work for me and that is a 325 gr. with a double crimp groove. I just figured that since the barrel for my 45 Colt was for a 454 that it might be a slow twist for lighter boolits in the Casull.

If your going with the 325 I would use a plain base.

Although I am a stickler about twist, there is a LOT of latitude.
My dislike are real slow twists where enough velocity can't be reached with heavy boolits. A rifle can have a slower twist up to a point.
Odis, are you sure it is 1 in 20". BFR .454's are 1 in 16".
The new .44 Shorty is also 1 in 16".

The new .44 Shorty is also 1 in 16".Yes I'm sure, I bought the gun in 2009, all their 454s had 1 in 20 then, not sure when they went to 1 in 16 but sometime after. I'll probably be using straight wheel weight alloy water quenched at first, sizing and lubing as needed.

It should shoot fine. I am sure you will get it to shoot. Might need to have just a little more velocity. It will be interesting to see your results.

If you are planning on going heavy I would strongly suggest one of Tom's 340 grain bullets. I know of 2 other members besides my self that have his 340's the ones for the casull and the 340f. We all also had the 300's we all have gone strictly with the 340 because the accuracy is better and it is easier to find loads that work well and we all have plain based bullets. I love my 340 mold from Tom and it shoots great out of all 4 of my.45's

Yes. He should post his results. It is always good to see the results. :popcorn:

In another thread I posted that I had purchased the 45-325D mold from him. I haven't received it yet. I also ordered the 45-270K from him for my Black Hawk, that gun really likes that bullet and the size for that one is 454, the Ruger is an old one and has 454 throats. I'll let you guys know when I get some slugs cast and how they do. Thanks for the interest.
