Wildcat just made for a Handi?
« on: September 29, 2009, 05:51:05 PM »
I've just about got my 30-20 reamer built, 30-30 necked down to 20 Cal.  I think it will just clean up a 204 Ruger chamber, have a rim and a little more zip than the standard .204.  The reamer is made from drill rod, then ground in half to make a reamer, they cut slow but work realy well.  The drill rod machines really well and then it is water hardened for cutting.  I will post some more pictures  as I go, but you can make up anything you like, as long as any cutting edge has some taper to it.  The rim would have to be cut seperate as a straight sholder will not cut in this type of reamer.  Larry

I don't know if it would go faster than a Swift, the Swift had an advantage of a larger bore and a lot more powder, so the 30-20 would need to run at a higher pressure to get the same speed.  It will go faster than a 204 Ruger however.  Larry

It looks interesting. Any body taper to it? Looks like a short neck too - shorter than a 30-30 neck any way. I really like rimmed cases in a break open single shot rifle. I think you have a winner here. You can keep the pressure low and still get decent velocity, ideal for a Handi. What about dies? Do they make them or would it have to be special ordered? So many questions.

Shouldn't this be called a 20-30 ?

The .225 Winchester necked down to .20 would be interesting, but it wouldn't really gain anything over the original cartridge.

Don't know if this helps but the .219 Donaldson-Wasp is basically a 30-30 necked down to a .22. With a 50gr. bullet depending on powder and the load you can get 3,200 to 3,600 feet per second. It is quite an efficient round.

Looks good!  Doesn't look like you improved the shoulder, any reason why not? The reason I ask is you are building it for a rifle that you don't have to worry about feeding problems, and I don't think there will be any extraction problems with that big rim either.  Plus I've always read that the .30-30 case is one of the best ones to improve, I know my buddies .30-30AI pistol produces some impressive results across a chrony, and was able to kill a pronhorn buck at 225 yds with a 125 grain bullet at nearly 2600 fps out of a 14" barrel. 

The .204 Ruger equals the swift in factory loads with a 10 grain lighter bullet on average, example 32 grian .204 and 40 grain .224 are both pushed at 4200 fps.  I'd think that you should be able to get a 40 grain (3900 fps factory Ruger) .204 close to 4200 fps with the larger case.  Interesting little cartridge you are building that is for sure.

So once you get it built and tested, how much to ream a guys barrel and dies so he could play with your creation??? ;D

OK, 20-30, that is better.  I left the sholder angle the same for ease of making brass, and to tell the truth I am chambering a Steyr straight pull bolt gun for this, so that is why I left the neck long, I need the length for feeding, but it is a natural for a Handi.  Because it is a rimmed case it could be as long as is needed to clean up a .204 chamber, then the shoulder would be blown forward to match.  We will see, I don't think you would really need the case capacity that an AI type would give you.  Larry

I cut the chamber toinight, not bad for a one off job, the reamer cut well, this is a cast, I will polish the chamber up some and cut the throat seperately, but I think this will work.  I will just grind more off the reamer and make a sizing die with the same reamer.  Larry
