Well , I have shot Winchester 260 Partion Gold, 250 Barnes XPB Handloads ,300 Hornady XTP Mags, and 230 Speer Gold Dot HP's,all Handloads except for the Winchesters that I got a great deal on.Now as far as accurate they all shoot excellent. I have shot deer (NYS) with the 300 XTP's not real impressed with expansion ,but they do work. I guess next year I will try 250 Barnes XPB ,even though G.B. tested them and did'nt think they would open up good. The Barnes MZ'S open like advertised in my muzzleloader,never lost a deer yet :-D with them. Of course I am a much better shot with a long gun. Also am very anxious to try these Win. Part. 260. Both these bullets shoot very well at the bench,1 inch groups at 50 yards .I love this Raging Bull especially since putting the Halo sight on it. The best part of all this testing is they all shoot the same with no sight change,except for the 230 Gold Dots. witch shoot low and rt. about 3 inchs. Why do they not put a cannelure on this bullets ? Well guess I have rambled on long enough ,Boy deer season sure seems a long way off!
