What is the twist rate of the barrel and how long is it ? that way I know what data to send you , I have loads that work very well in my 20" 1 in 16 twist barrel and loads that work well in a 14" 1 in 12 barrel .
As for the 17 brass , trying to bring it back to 218 Bee may be next to impossable as the cases have been moved a ton to make the 17 and will also be work hardened , you may be able to Annell them to help some , but I dought it .
Check Midsouth and Midway , Win brass for the Bee was only about $25 a 100 when I got some awhile back .
