Heya cowboy... I have to concur with more magnification for distance work. I know there are guys here that shoot out to 1000 using nothing more than a 4x... but for me, I find that 15x to 25x really helps. Also... The better the glass, the easier it it to resolve your targets/game at distance. Many guys buy $1500 plus scopes and absolutely feel it was their best investment for their gun and shooting. I can't go that high, but I have been incredibly pleased with the vortex Viper PST ffp 6-24x50 I got last spring. I did pony up the cash for a vortex razor... but I found the weight to be a detractor for me. I sold a couple of other scopes on ebay and added to it to get the razor... But ended up selling it for the pst and couldn't be happier.
I'd like to get another... But money is tight... So....
Lastly... I would check out 2 more things... Ffp vs sfp. I love ffp and will never buy another sfp scope. Others feel exactly the opposite so I would encourage you to consider this before buying. Lastly... Even though I mentioned that I like more magnification, usually to get it, you sacrifice lower magnification. So on my favorite scope... 6x is the lowest I can go. This is ok at distance, but it makes fast up close acquisition challenging and isn't the best choice if you re hunting close quarter brush or woodland environments. Also... For coyotes... It makes it challenging if we get one that sneaks up and attacks our call or decoy. A 3-4x is much better under the above conditions. So consider all the ways you intend you use your rifle and under what conditions before you make a commitment !
Good lucky buddy!
