Was wondering about necking a 225win case to 6mm. Have not heard of many wilcats on this case. Thanks Jim

Used to have a 25-225 Win. Chambered in a T/C Contender. Somewhat comparable to a 257 Robt's.

The 225 Winchester case makes an excellent round when necked to both 6mm and 6.5...

I have a 6.5X225 that is loaded using a 6.5X54 MS full length die set and is basically just a "rimmed" version of the 6.5X54 MS. Necking the 225 case up to 6.5 is as simple as running the case neck over the 6.5 expander in the die...

Both the 6X225 and 6.5X225 are popular chamberings that I do in the H&R single shot rifles because of their high accuracy level with modest recoil....

Was a favorite case of J. D. Jones who offfered several .225 wildcats for single shot pistols (.226 JDJ, 6mm JDJ, .257 JDJ, 6.5 JDJ, etc.).

Maybe I'm not remembering correctly , but isn't the .225 Winchester basically a .30/30 case necked down and rim turned to .490 so it is compatible with .30-06 base for use in bolt rifles?

If so it would seem that any necked down .30-30 wildcats would be similar.

Gene,

yeah it is kinda sorta like what you describe...

I use both the 30-30 Winchester case as well as the 375 Winchester case necked down, trimmed and loaded using 225 Winchester dies. This round has been popular with our custom barrels for the H&R single shots...

the 375 Winchester case is preferred because of it's greater strength. The case is first necked down in a 30-30 full length die, then a 7X30 Waters die, a 260 Rem. die, a 243 Win. die and then finally full lenfth sized in a 225 Winchester die. Since I cut the neck as a seperate operation from the body chambering, I can cut the neck so that no neck tuurning or reaming is required or I can cut a tight neck and set it up as MATCH chambering. The case neck is also annealed after is is necked down in the 7mm die and then again after being sized in the 225 die...

This bigger "rimmed" 225 Winchester round makes extraction easier and the strength of the 375 Winchester brass allows for MANY firings. I have cases that I have fired over 30 times apiece and the primer pocket is still tight and the brass shows no signs of weakness. I have not hot-rodded this but am shooting the Hornady 55 gr. V-MAX to right at 3,500 fps. from my H&R....

Assassin, what kind of numbers does the 6.5/225 show with the 108 gr SMK Thanks Jim

Jim,

the 6.5/225 - using the 375 Winchester case left full length and with a short neck, will do around 2,500 to 2,600 fps. with the 107 gr. Match King bullet. A lot of guys use this bullet for bustin coyotes as it does very minimal pelt damage. The light recoil and outstanding accuracy make this a fun round to shoot....

whats required for neck turning?

FORSTER makes a relatively innexpensive neck turner and SINCLAIR INTERNATIONAL carries several deiiferent types of neck turners...

When necks are to be turned, it is to remove excess brass of thickened necks and to give a very uniform thickness around the complete circumfrance of the neck for a more precise release of the bullet...

Example: when micing the neck diameter of a loaded round for my 6mm Bench Rest, it mics out at .273. The neck diameter in my chamber is .262. I therefore turn my neck diameters down to .260. This allows for .001 bullet clearance per side and allows for the greatest accuracy potential out of this particular rifle....
