Both the 7 STW and the 7 Ultra are over bore cartridges, so if you are going to shoot the big bullets
go with the big RUM.
I have both, and the STW will hum the 140s and 160s. but the 7 Ultra does better with the 180s
because of case capacity and slower burning powder.
The 1 in 8 or 1 in 9 twist both work in the Ultra mag so If Berger recommends a 1 in 8 go with it.
