I love my 2 Crosman 1377's. One's scoped the others iron sights. I have a 17 yard pellet range in my crawlspace. with 10 gr pellets at 400 and 450 fps mv these guns are as much fun as any PB's I shoot. I shot a 2.5" group with the scoped one at 50 yds. couple weeks ago and the ballistics from Chairgun was almost dead on the nose. The iron sighted one I use for long distance MOA and Mil calcs using the front sight measurement vertically and horizontally vs the sight radius, and I can reference shots to 80 yds. with it...including windage calcs. These are great platforms for angular math calcs. and it's really fun with them.
