If I can figure out how to post a photo from my cell phone I will do that later. Anyhow, I took my Three Grandsons aged 7 to 15 out on a trip to the West Desert in Utah yesterday. We were driving around in my Polaris General 4 seater. There is a creek called Cherry Creek that we check out regularly for Jackrabbits. Porter Rockwells old ranch is near there somewhere, but I am not sure exactly where it is. The rabbit population is down from where it was four years ago but seems to be on the upswing of the cycle as last year we did not see but one Jack. We covered a lot of ground in the General and ended up seeing 6-7 Jack's. Four years ago at the peak of there cycle, we would see around 30. I got one with the 257 Jackrabbit at 25 paces. The boys got two more with a CZ 22 Magnum rifle. Incidentally, my load for the 257 Jack-A-Nator as I call it, is the 55 grain Hollow Point from GT Bullets with a Rem.# 7 1/2 primer. I have found 10.1 grains of SR 4759, to be accurate and gives me the most velocity I can get without the cases sticking in the cylinder. You have to use a Drop tube to get 10.1 grains into that tiny cases. I have taken 12 Jack's with my .257 so far since receiving it from Mr. H. I had a good time and I am sure the Boy's did to.
Happy Fathers Day to all.

Sounds like a great time with a great gun.
I love my 250 GNR and 25-20 Revolvers with the GT Bullets too.

Cool!
I'll send you a message, and if you want I can put a photo up for you.

Good for you taking those 3 grandson's, great memories for sure! Use to live in Milford & there's a lot of wide open spaces west of there. My old 25-20 & the Lyman #257420 took care of a lot of Jackrabbits, I'm betting your 257 Jackrabbit is a real hoot on them!

So Horvath put that one together for you? Did he do the dies for you too - or how are you assembling the ammunition?

You just form the brass from Starline 32-20 brass. I use a special form die to do that but it is readily available. Once you have good 25-20 brass in hand you simply trim the case to the proper length and load. I like to fire form the brass once with some common 25 caliber cast bullets and then I make up my hunting ammo as described in my opening post. A bit of a process but if you enjoy Hand loading it is kind of fun.

38 WCF: I HAVE TRIED TO FORM 25-20 OUT OF 32-20 USING 25-20 DIES BUT THE REFORMED BRASS WILL NOT CHAMBER IN MY 25-20 REVOLVERS. PLEASE PROVIDE INFO ON THE SPECIAL FORM DIE YOU USE.

Redding makes the 25-20 trim die I use. If memory serves, I run a lightly lubricated 32-20 case into the Redding 25-20 trim die. Then I run the formed case into an RCBS 25-20 size die. Then I Trim to length. Then I run the case into a Lyman .25 "M" die. This "M" die expands the case mouth to properly seat a soft cast bullet. The case is then ready to load. You will lose some of the cases in the process. Maybe 7-10 out of a hundred.

This is a common problem. The 218 Bee and 25-20 are slightly smaller across the base than the 32-20. On a tight chambered gun, it's a no go. The very bottom of the brass won't size down enough because it won't push into the die. Formed brass fits my TCs, etc. But, not my Reeder or JRH 25-20s. This warning is posted on the Starline Brass Site. Winchester brass will work. Easy to convert Hornady 218 Bee brass.

Thanks for posting this! I am getting ready to start building my 257 Jackrabbit and looking forward to putting it to work. I managed to find a few hundred new Rm cases on GunBroker a few years ago, I only have to trim them-up rather than forming new ones.

As far as I know Alan has the only reamer but I think it wore out after about three uses. There may not be one anywhere today.
