RE: .280 reloads
Fail Safes are a bullet made by Winchester. Iam using the Combined Technology ones made in conjunction with Nosler.
A mountain rifle is a shorter barrel and smaller diameter barrel. Thus it is lighter.
I personally think that the best rifle for the money on the market is a Tikka. The bad part is they dont make a .280.......but I already have one so that is not a big deal to me.
With the Fail Safes (160 gr.), I find that they are flying identical as the Combined Technology Nosler Ballistic Tips (150 gr.)
they are both very accurate....I was looking for any real world experience on the fail safe bullets in the field.
