The 60s work ok for me with longer barrels and slower powders like 1680 as long as I stick with standard primers.
Erratic with Magnum pistol powders or primers.
They do well in my 255 Banshee revolver, however. The Hornet case improved and necked up to 25.
Case is very straight and has reduced capacity compared to the 25-20. Using H110 provides 1800 fps with very low spreads.

pretty good shooting for the wind... were you shooting into or behind the wind, or cross wind in those 40 mph "breezes"

Fortunately the wind was at my back.

I saw on the national news today Neverland is for sale!
Seriously...train station and all.
Glad you're getting back in the groove and maybe feeling a little better.
I trust you'll get it sorted out.

I'm sure it will be excellent. Wish I had Jeff Hoovers help on this one! He really did a job on the 32 project!!

I did some 100 yard shooting with the .257 Jack Rabbit and the 9.5 grains of Lil Gun on the Hornady 60 grain jacketed bullet with a Winchester small pistol primer yesterday evening. The wind was semi in my face at 11 o'clock and at 22 mph and gusting hard. It was evidently too much for me to land 5 shots on a paper plate. Best I could do was 4 shots out of 5 BUT the 4 of 5 were in approximately 2.5" high by 4" wide pattern. AND, the .257 Jack Rabbit is a shockingly flat shooter. Or said another way, with the little sixgun sighted so that the bullets pattern about the top edge of the front blade at 50 yards, at 100 yards with the same hold, the bullets land just under the top of the blade. I was very impressed with it. Recoil is hardly noticeable. Report, however is stout. Afield, one better wear ear plugs. Accuracy, when one can hold it, seems consistent enough to plant a searing jacketed lead core bullet within the confines of any unwary Jack Rabbit who has not been warned of our little wildcat.
Alan Harton really outdid himself with this fine little sixgun. Also, I recently acquired a 25-20 Marlin lever carbine. Trim and delightful, I will probably mount a scope on it to see the full accuracy potential of my little warrior cartridge. I am curious to see if the shortened 25-20 will function or if I will have to load my JRs "long" to get them to work right in the little Marlin. It will also be interesting to find out how much velocity we gain from a rifle barrel.
So, more work remains.

That is wild!! Great results!! I tried to shoot a little over a week ago and had about the same situation. Too much wind. I went back and looked at some of the load info I sent you. I had written down 11.5 grains of LIL Gun. One thing I started thinking was, That little gun of yours might just put the POI the same at 50yds or 100 yds, with that little extra powder. The other thing that I wondered about was how much powder was burned? What primers did you use? The reason I ask was, the 9.5gr. load showed only 67% burn and the 11.5 gr load showed 80% burn. I realize that Primers are going to come into play with this. But, Did you notice any unburned powder?
QL showed that 9.5 load to be at 1471 FPS If you have a 20" Barrel and can use the JR loads (as is ) then it shows 1911 FPS 440 FPS increase Sweeeet HUH?

Great update! I've been looking into those 1894 CLs as well with thoughts of a Jackrabbit pair. Out of curiosity, does yours have microgroove or conventional rifling? I have to get moving on hollowpointing that 257420. When I get it done would you want to try a few?

Charles Hi Charles, I used Winchester Small Pistol primers, and no, I didn't see unburned powder. I will shoot the 257 JR load out of the Marlin 25-20 on a day when I can be reasonably confident my chronograph isn't going to blow away!

It also seems as though the 257420 bullets are going to have be seated so that the gas check is well beneath the neck. We haven't finished making the sizing die, but once I do I can test some just to see if the gas check will stay on during flight. Of course, if they do, I will have to have some of your hollowpoints.

Fermin, First off I do not blame you for being wise with your chronograph. I had mine blow over once, and that was enough. That is very good news about the powder. I was concerned with this. Thanks for the info and write -up. I hope your continued success in this. I do look forward to some of your cast loads also. Charles

Charles, I shot the 257 JR some again today. The results can be seen in the 100 yard and Iron Sights thread. I looked specifically for signs of unburned powder and I did see a few granules but nothing to cause concern.

Fermin, Probably not much different than a little H110 being left behind. That is good about the powder. At 11.5 there should be no powder unburned. The quick load showed it to be over 87%. But,, As you well know that increase in powder just these 2 grains needs to be watched in the small cases. The quickload showed it to be less than 28,000 PSI Now as Lee has said nothing takes the place of a good chronograph and a pressure test barrel. And when comparing loads from the MFG books and see what QL says nearly every time the QL says over pressured at the Books max. But if you stay at this level, I am happy with you. If you decide you increase a little, it probably won't take but one session to see if the group gets bigger, smaller or stays about the same. Let me get over to the other post and admire your results.

I think 9.5 grains of Lil Gun is about maximum. I plan to try 680 next, it did show some promise in early testing but we will see what we see. I just wish more dedicated sixgunners had one of these little poppers so I could have some guys to compare notes with. Till then, I gotta be careful what I post as to loads.
