Hi Gang,
Looking to buy a 219 Donaldson Wasp sizing die. I got a Ruger #1 in some oddball chambering that works out to be "about" a 219 Donaldson Wasp necked up to 7mm. "Ideally" I would like to get an old Herters Wasp die and then drill it out to the proper dimension for a 7mm and then load for this thing. I have made brass for it using 7mm BR Remington dies and 30-30 cases but it [7BR die] will not full length size the case and I foigure, when I go to higher pressure loadings , it`ll need Full Length sizing. Of course if you got a better idea let me know too. Appreciate the help.
Aloha, Mark

Are you sure you will need to fl size for a Ruger No.1? My experience with No.1 's in 22-250 and 218 Bee never required fl sizing. Wilson makes 219 Donaldson neck dies and seaters. I believe you will find the opening in the neck die where the bushing sits large enough to accommodate a fired 7mm neck or Wilson can open it up. For example, the opening in a 204 Ruger neck die is .350. They may also be able to open the neck area of a 219 Donaldson seater and enlarge the seater stem hole for a 7mm stem. I recently had them modify a 204 Ruger seater for my 22-204. One day turn around at a cost of $15 plus $8.50 shipping. I supplied the 22 cal. stem and cap.

Mark, Looking at E. Arthur Brown Co. website, I see they sell 7mm US(Ultimate Silhouette) dies and brass. They indicate that the 7mm US is the 219 Donaldson Wasp necked up to 7mm.
