One of my favorite scopes of all times was the older Japan-made Tasco World Class scopes. They're hard to find now, but a friend of mine gave me a fairly new Tasco 3x9x50 World Class scope the other day. I know that the quality isn't there anymore, but it fit perfectly in the Redfield rings on my 700 BDL .270. The optics are crystal-clear. Anyway, I've never had a 50mm scope before. Do they collect light alot better than the 40? Thanks for any replies.
