Just picked up this old Vixen and with reloading supplies being precious and factory ammo nill. I was looking for advice. Have some 50 grain TNT plus a mix of other 50 gainers and 40s but don't want to waste what little there is. The barrell is being recrowned so I plan to shot some coyotes soon. Open to any suggestions from someone who has loaded for a 222 Vixen with success and something other than IMR 4198, since I don't have any. Thanks
