mtrancher congrats. My 1-10" stabilizes 140 Gamekings just fine. Shoots 120 nbt's great too. That is all I have used so far but am betting the 130 hobt I nearly went with would fly just fine too.
I was reading another post where 1-10" would not shoot 120's and the Remington rep told him to use 140's and things improved against the common thinking. This very thing got me reading on Miller formula and Greenhill and JBM- evidently it isn't weight but bearing surface size that matters most- then speed.

Admitted novice- flame away.

Congrats on your 260- it will be your new favorite.
