Don't sell yourself short on magnification. I had a NF 3.5-15x56 on my rifle for 1 week. Traded it for a 5.5-22x50 NF, much better. With the NF scopes, there is almost NO difference between ANY of the nxs scopes when it comes to size and weight. Even the 8-32 is only a few ounces heavier than the 3.5-15, they will all feel like a beast compared to the burris you have now (almost 3x the weight). I have been through 6-7 scopes in the last couple years on a coyote/ground hog 223, from Swarovski z5 3.5-18x44 (really a disappointment), vxIII's, most recent was sIII lrmoa 8-32. you will find either sightron fantastic for varmints. I shot running coyotes near and far at 8x, the 56mm gives a good field of view. The sightron and the nxs scopes are roughly the same size (big!), so no real trade off there, but the sIIIs are lighter. The only issue with the sightron I had was the lrmoa was so fine I missed a coyote in low light, had a tough time seeing the reticle, that's when I decided I needed a NF with illumination. I did go for the 50mm and was surprised that the 56 did look brighter. Sightron has a 6-24 in FFP out this year that is illuminated, but I don't care for the battery on the eye piece, had them before. It may be my eyes, but I really preferred the sightron at 20x and above to the Swarovski. I had trouble seeing .22 caliber holes on a target at 200 yards. The NF is in a class of its own, good optics, but rugged and smooth. It doesn't do a lot that the sightron wouldn't but the quality is inherent, also I am very pleased with the zero stop and high speed dial. If you go NF, even used, don't short yourself.
I have found what I think could be the perfect tactical style scope for hunting, have to get my hands on one: march 2.5-25x42mm. not sure who sells them in Canada, but kelblys has them in Ohio, looks like $1700 without illumination, $2300 with. only 12.4" long and 20 ozs (2" and 12ozs less than NF!). Sorry for the rant, all of this is only IMHO. If you don't mind the weight, you will very happy with the NF. I coulda bought an S&B right out of the G
Gate and be money ahead of where I am now... Buy once cry once....
