Re: Heavy Barrel or not?
If you're going to sell the rifle, keep in mind that you can then buy any rifle you can afford. Unless you need features that are specific to the Police rifle, it can pay to consider a Varmint rifle.
I like both the Rem 700 VLS and the Savage 12FV. The VLS usually comes with a 1:12" rifling twist (which handles 55gr for sure, 60gr maybe), the 12FV uses a 1:9" twist and is better suited to heavier (69gr for sure, 75gr maybe) bullets. My experience with both is that either rifle's factory barrel is certainly good enough to use up completely before rebarrelling with a premium aftermarket barrel.
