I usually use the 1910 flat base. I do have a box with over 117 in it of the 1905 though. 2/3 of them are pulls from 7stw ammo that I went with the accubond instead on. They were pulled with an rcbs collet puller. Let me know if interested. I haven't bothered with them in my 7mag yet as that pipe already likes three other bullets. $20 + shipping...
