Last year I shot 120gr 777 with 290gr Knight� EZ Load Ultimate Slam Series� Polymer Tip Saboted Bullets,a.k.a. Barnes TMZ. These were hard to load in my Omega, so I ordered some different sabots from mmpsabots, which were easier to load, yet fitted snugly in the barrel. I was very impressed with the accuracy and performance of this combination. If you're interested in the mmpsabots, pm me and I'll give you the size I ordered. They're $10.75 per bag of 50, delivered.
