Man I hate too hear that he is who barreled up my 25-284 last year , he was really a nice man and easy too deal with . He did a great job , or had one of his employees do the work , but I think he did the work.

That's to bad to hear about Stan Taylor. I have used their barrels in the passed, and they there job of me. No complains about there barrels.
Did you look at the .25 Sherman by chance?

No I didn't and wasn't aware of it either. I kind of like the powder compacity there. Plus I have about 1000 case in Peterson Brass in 280AI.
I fire-formed Lapua and some new '69 Lake City match brass, but the downside is a shorter neck. HARD to kill the primer pockets with either of these two types of brass. I used 14g of Bullseye and cream of wheat to fire form with. Accuracy was stellar with both brands of brass at warp speed pushing high pressure.
Forming the brass is a good Wintertime project. I got a 40-gallon trash can, cut a 3/4" hole in the bottom, wound up a roll of Finger Foam and placed that in the trash can. Finger foam is the type that is used in beds to keep old folks from getting bed sores. I fire-formed the brass right in my garage, turning the trash can upside down, and placing the muzzle about 6" down in the finger foam. This produced a very quiet fire forming.
The Lapua brass is particularly tough in the case head, and the Lake City is no slouch either.
All of this fire forming is a tad bit of work, but a guy that likes to tinker needs to stay busy.
To keep doughnuts from forming, I neck turned at 30 caliber, then necked down, never had a problem with doughnuts as part of the thinned neck became part of the shoulder. Neck turning would not be a bad practice for a guy that is necking down 280 AI brass either.
Since I never shot full-length necks, the carbon issue in the necks was never an issue, but a few twists with a brush .015 larger than the neck kept the carbon to a non-existent issue.
I shot that barrel out on Coyotes, rock chucks, and long range jack rabbits. I never wore the brass out. 100 '06 lapua cases and 100 New Lake city brass lasted the entire barrel.

Do have any spec or dimensions on the Sherman case? I have seen some loading in the Sherman case in different calibers. I download them into a file. I didn't see anything on 257cal. I'll have to go back and take a look. Interesting.
Does Rich sell dies?
Yes.

i did read about you fireforming your cases. I had the smith order a 2nd action to set for fireforming my cases. I have an extra stock from to place the actions into to do the work. I'll find two barrels in the calibers I going to use and have them reamed to those case dimensions. I'll just change out barrels as needed. My sons will be set for life.

Used LC Match brass from the 60's to do my 6mm-06 AI and my 25-06 AI Thats all we had back then. Now have factory brass so sweet. Good luck out there with your toys. Shot straight and often.
Its been a very very long wait but I got it back this year. A lot of the decisions I made were influenced from this thread, so my first custom rifle was a leap of faith but the advice here paid off.
Since last time I have been learning to handload, I wasted no time on this one. I built this rifle around the 127HHT bullet, custom throated to optimize case volume for velocity. I wound up with a 26in 7twist Ackely Improved chamber Douglass barrel, blued and fluted, custom throated for the 127gn Hammer. Bedded and floated to the original wood stock I refinished myself, sealed inside and out with tung oil.
I settled the new barrel in on some old factory ammo, plus 50rds of new virgin 25-06 Norma brass fireformed with some spare cup and core bullets I had acquired. It was fun watching that virgin brass come out as an ackley...
I ran up to 60 grains of H1000 and found pressure with some ejector marks. I backed off to 58.5 and running 3111fps average for a .3moa group at 100yds. Ive never owned a rifle that shot this good, Ive never shot a sub half inch group before. I was hoping for at least 3200fps but I cant complain...
The 127HHT has an advertised G7.262 and a .275 sectional density, at 3100fps this puts it on par ballistically with larger traditional calibers using (close to) the same bullet weight. This is a win and I look forward to getting to know the new rifles potential. A special thank you to @ButterBean , @B-LOT Banga , and @FEENIX for the confidence in advice and offers to help.

That's a sweet looking rig
