25 SHERMAN (THE LATEST LASER)

[couesaddict13]

What are you using for dies @Phil Rizzo ?

 

[Phil Rizzo]

Well, I've never had a 25-280AI.
But I retired a 25/06AI for an extra 75-100fps.
I use a Sherman/Hornady bushing sizer and an LE Wilson micro-seater made with my reamer and gauge.
heres the factory, AI and Sherman LA lined up.
The reduced case taper is impossible to see but I've got a reamer print if needed.

If you already have 6.5x280AI dies it would just be a simple bushing change to go to 25x280AI

The sherman would have more speed but not a whole lot more.

The Sherman has less taper than the A.I. and the shoulder is forward of the A.I about .032" I think. More capacity and still has a good long neck for a 25 cal at around .297".

Thanks for all of the info, I have been digging across the internet for days. I should have started here.

Appreciate it. Preferred barrels has a reamer for 25 Sherman already. I just will need the specs so I can have Hornady make me some dies if Sherman wildcats doesn't have any.

I am contemplating building a 25 Sherman. Is the 25 Sherman the same thing as a 25-280ai? Could I use my 6.5-280ai bushing dies and just change the bushing? If so what size bushing would you recommend? Thanks, Grant

I built not 1 - a 25 S - but 2. a 6.5S. Both are incredible shooters, built by LRI on Terminus Zeus actions with Bart Barrels. Wouldn't change a thing. No - not the same at 25

Thank you for clearing up my questions! Would you recommend a Sherman over 25-280ai? @Phil Rizzo

Only if you want more speed than the Ai.

@elkaholic has dies.

That's Mr. Sherman by the way

 

[couesaddict13]

I like trying new things, have you had to turn necks for the 25 sherman?

I think carbon 6 has reamers for most of the Sherman wildcats also

 

[couesaddict13]

@elkaholic I'll need dies, I'm gonna go the Sherman route.

No neck turning was necessary for Me with Peterson brass.
I haven't even trued them.
However I did neck down in 2 steps and annealed after forming.
Not 100% necessary, but I had the time and access to an AMP machine.

Peterson brass was what I was going to use.
