I've shot at least few deer with just about everything. Cup-core, monolithic, bonded, partitioned, ect from all major companies, Sierra, Nosler, Speer, Swift, Barnes, Hornaday and Berger. Always looking for that "MAJIC BEAN"
After shooting a lot... It's hard for me to pick a favorite. This year I'm shooting gamekings in .243, V-max in 6BR, BT & prohunter in 6.5x47, Accubond in 7mag, BT in 300 savage and gameking HP in 6x45... Havn't took anything else to the deer woods yet
. Though I did kill 2 good deer with the Hornaday 300gr XTP mag in MZLDR season.
If your shooting 30 cal, just pic one of any, they will all work. I have no doubt that in poor shot situations (texas heart shot comes to mind) that some of the Barnes style bullets or bonded will give a slight advantage due to extended penetration. However, for pure pile 'em up quick value. The sierra gameking followed close by Nosler BT are hard to beat. Plus thay shoot well in about any gun.
Whatever shoots best in your gun, go with it! If you don't reload, look to Hornaday customs or Federal Premium line... If money is an issue. Pic up a box of Rem Corlocks & don't look back!
