I've been using Reminton Core-Lokt express 180 grain ammo which grouped well. I thought Rem had discontinued it untill I looked at Cabela's Great Outdoor Days mailer. I was happy with 3 dead deer in Sask. , but was not exactly happy with the weight retention, or finding the jacket of the bullet falling to pieces upon skinning the deer. All 3 shots on 150 class and higher deer were from 70, 40, and 111 yards. Before we start the "it killed it dead didn't it" or the "who cares if you didn't get a pass thru" argument, I'd like to ask what factory ammo/bullet has proven best for you? I do not reload ammo. Horndady, Wetherby ammo, etc. Thanks Wanna kill these ads? We can help!
