Re: new to wildcatting...help!

Hi Coyboy, Jimm,
My advice would be to hand load from the start for your 243 Ackley, this way you can get quality brass and may be even surprise yourselves with some outstanding fireforming accuracy
I do not have any experience with this cartridge yet, but have fireformed many 220 russians into 6mm PPC. I seated the bullets hard into the rifling to stop the case moving forward in the chamber when struck by the firing pin. this allows the brass to flow forward to fill the chamber, rather then backwards, which is what happens when the case is driven forward by the firing pin untill the shoulder contacts the chamber. In severe cases weakening of the case head can occur.(the same as excessive headspace)

Try Mike Js 6mmAckley reloading page at: www.angelfire.com/sd/6mmackley for a good discription of cream of wheat fireforming, its economical but i would still prefer loaded round fireforming.There also some beautiful rifle pictures and many good tips.
My smith has 6 month waiting list, so my rifle wont be going into his shop untill August. [img]/ubbthreads/images/graemlins/frown.gif[/img] [img]/ubbthreads/images/graemlins/frown.gif[/img]

Re: new to wildcatting...help!

Centrepunch ,thanks for the advice.I too would rather have a loaded round for the initial fireform simply because I can make a hole in something [img]/ubbthreads/images/graemlins/cool.gif[/img]What will be your regimen when you receive your ai.I mean like step1 ,step2 etc. What dies will you use?, so on and so forth.

Re: new to wildcatting...help!

For the wildcats, yes, that is what I do. Most will last up to a dozen firings. I feel that is plenty for case life. All wildcats are based on some readily available case - some more expensive then others. I use this method simply to ensure that the brass fits the chamber as precisely as possible.

I have resized some more common cartridges. Brass survived another firing or two but best accuracy didn't occur until they were 'fireformed' again. At which point, I am just wasting time and components. so I use the brass until it doesn't chamber properly and pitch it.

If you use the COW method, you only do it once. For most cases, it forms to 90%. A full powder load with a bullet does the rest. I find this method much better when I have to move shoulders forward. Seems to put less stress on the head web thus I don't see case separations after many firings. Also, very gentle on necking up brass and I usually get no splits. With a bullet, you can do the same thing but it just adds cost and barrel wear.

With a light load and COW, you can fire 30 to 40 cases before a heavy barrel gets warm. In one session, you have formed all your cases. Swab out the bore and chamber every now and then to get rid of any loose COW. Dead simple to use and very high success rate.

Give it a try...

Jerry

Re: new to wildcatting...help!

Jerry - thanks for the info. I have about 50 rounds of once fired brass already loaded for the little 243 and I think I'll pick up some new brass and try the COW thing and see which results I like best.

Question - Does the cream of wheat method help or hinder the neck length problem associated with fire forming AI cases from the parent case?

Queation - Should I be using new brass for all the firforming no matter which method? or is previously once fired brass not work hardened enough to matter?

Re: new to wildcatting...help!

Jimm - Here are a couple more places to go for some info as well.
www.varmintal.com
www.accuratereloading.com
www.angelfire.com/ma/ZERMEL/ (Fred the reloader)
The more I look and learn the more excited i get about it. I definately need to get me a neck only sizer as several places have suggested neck only sizing after the cases are formed.

Re: new to wildcatting...help!

Cowboy, I know what you mean, seems theres nothing like waiting on a new project in a "new" caliber to put excitement back into reloading /shooting.Thanks for the additional info/links to you and Jerry. At this point I'm leaning toward redding bushing neck die And comp bullet seater for my new toy.BTW what barrel and rate of twist did you order?

Re: new to wildcatting...help!

I'm having my son's factory rifle tuned up and rechambered for AI due to poor performance out of the box. Ruger 243 ultralight sporter 20 inch barrel 1/10 twist(I think that was stock). Getting rechambered/barrel setback/action trued and lapped/trigger job/bedding in new stock. I'm hoping this fixes the problem. I still may have to put a new barrel on but this one only has about 200 rounds down the tube so we will see. I think I'll be getting a bushing neck die soon. I have to decide if I want to start fresh with new brass or use what I've got on hand. I still have about 50 rounds loaded for the 243 and another 100 or so once fired brass. I hate to throw it away. It was going to be for my kids birthday but he talked me into trading him for my 22-250 which is sub moa out of the box. All the work is now for my gun. He'll be sorry when its completed.
