I am looking for a new scope for my .308 Remington 700 sps varmint. I currently have a viper he but even with my 20moa seeking base I only have about 37moa left in the scope. So I'm looking for a scope with plenty of elevation adjustment range. I definitely want a ffp. Basically wondering if the PST is worth it over the SWFA 3-15x42. And if the SWFA 5-20 is worth it over the PST. I'm also open to other scopes too in that price range. I now the SWFA scoop less don't have a zerostop, which I would prefer but it's not a real breaker.
