N560 showed the best possibilities with more load development. Overall conclusion Lost River Bullets will work, however it will cost you and arm and a leg to find the right loads if you dont get lucky the first go around. When working up loads with this same rifle using Berger 180 grain I used load data from Accurate Reloader website. More load development should produce better groups with LRBT. My thoughts are for the cost and what they claim to be able to do (LRBT) the Bergers win hands down as they required no bank loan to procure enough bullets for testing purposes. I do like the LRBT and will order some more but for the low budget reloader, he or she may see better gains using Sierra, Berger, or JLK's. Lost River Bullets require finicky settings and I'm sure I will dump a few hundred into buying more to find the correct load. **********DISCLAIMER************ Information contained herein should be used as a reference only and all loads should be started 15% below stated weight.
