Cooper, ya can't get too much XBR in a fireform... Ready to fireform 6mm neck .220Russian case.........
Simply get the forming load to half up the neck (plenty room for the bullet without compression)..

Then fire away... But... Do you have a bit faster powder available.... H322, say...?... Reason being, is that XBR may not 100% fully fireform your brass.... 95- 98%, but not quite to a sharp edge forming....
Heck, even a faster ball powder will do... H335, AA2230.......... Stick powder like 4198.....LT32:o

Good fireforming!

I used H322 the last time I fireformed, but I don't use this powder anymore. I have someIMR 4198. Would I fill the cast to the neck or is this too much with 4198?

Thanks,
Matt

Matt,

about 26.0 - 26.6 gr of 4198.... Right to the shoulder neck junction... Plenty to get a nice forming.
Shoots good too..:o

Hmmm. There are two 4198, IMR4198 and H4198 extreme. I have both but haven't used any yet so I don't know how different they are. My IMR4198 is an 8 pounder in a tin can that has been around unopened for many years. Anyone like to chime in on the difference between the two?

I used 28.5g of 8208 and Hornady 58 vmax for fireforming recently. I had to tap the cases to get the powder level down a bit. This load also worked great for removing some oak branches in the way of the 300 yard range.
Good luck,
Bill

difference between the two?

Jerry I believe the burn rates are so very close...... Some think H4198 is >just a tad< quicker...?

The difference for me is the Hodgdon version has a bit shorter length.... Bit better through the measure..
And...... Just awesome in the 30BR..
Still, my two .222's like the IMR version.... "Just a bit"..
