I believe accuracy depends on the particular rifle. I shoot the Barnes in my 260Rem , 6.5x06 & 264 mag rifles with out standing accuracy Usually sub 1/2". . Have also shot the Hornady GMX with the same type of accuracy. They are both excellent bullets. Roll the dice. The Barnes does offer the 127gr LRX with a higher BC. If you check the drop tables in the Barnes manual you will find insignificant difference in drop between the any of them. The Barnes 127 LRX does give slightly less wind drift . Also insignificant. Having shot considerable amounts of Barnes & Hornady over the years I see no more copper left than when shooting a C&C bullet. They are all out standing bullets. Barnes does provide a larger selection.The 100gr Barnes TTSX will take the largest deer with ease. The 120 to 127 will do better for extreme range. Again pick which ever one makes you happy. No wrong choice here.
