Im getting ready to order some of the polymer tipped barnes under the Knight brand in 290 grain. They come in 30 packs from Cabelas for 16.99. I am going to try them in my new Revolution and break it in. Its funny that under the barnes name they are the 290 gr. MZ and sell at 20.99 for 24 from the same place. The 290 gr. should make for a good flat shooting heavy hitter. I will post some groups when I get them and can get to the range.
