I have a tikka CTR that is super accurate. 3/8 inch groups with Hornaday ELD -X. 143 grain bullets. I have killed exactly one deer with it, a doe at 275 yards. It seemed to work fine, but I have read of others having issues with this bullet. Anybody on here have any experience with it? My inclination, with a data set of one, is to keep using it. Any other experiences?
