Thanks for the offer. I haven't tried local gun stores yet so I'll give that a try first. I also need to look through boxes of parts (doesn't everyone have these!) to see if I might already have one.I may be wrong, but I've always used a #2 for 30-06 sized cases. A #3 will work but it is more specifically sized for rimmed 30-30 case sizes. Either one will work for the 308/30-06 based cases but the #3 is very slightly loose so may swage over the top of the rim if the sizer withdrawl gets "sticky".
Just a thought... Also, I've got several extra #2s and I'd be happy to send you one for only the cost of shipping- but even flat rate shipping is at least a couple times the value of the shellholder! You might try Fleabay. I see several choices on there for $10-15 shipped.
