I've been busy this week experimenting with .22s. Specifically, using CB rounds and their report. The CB ammo I have been using look nothing like the Wiki entry. I've been using the Winchester cartridge. I have used the CB rounds in a Ruger MkIII and Ruger 10/22. Both were very accurate with the cartridge, but would not cycle the spent casing effectively making both a single-shot/bolt-action -ish type of weapon. The reports on both were noticeably less...but not so much that no one would notice. I then remember I have a Remington 552 Speedmaster. I haven't shot this rifle in 30 years. The nice thing about this rifle is that you can shoot anything in it: .22lr, .22l, and .22short. It cycles them all with ease. However, it would not cycle the Winchester .22CB...AND, the CB report was louder than the short. So, just something to think about: .22 shorts are effective close range and have a low report (perhaps something to stock up on if you have the right weapon). Now, for my question: The 552's iron sights were probably beat up somewhat from all of the moves I've had in the past 30 years, so, I've had to adjust my windage all the way to one side (the front sight has no protection--I think I've bent it ever so slightly). Luckily, it is very accurate now--as accurate as my 10/22, but, I'd like to go ahead and replace the sights to something more robust. I would actually rather have a leaf sight for the rear if I could find a protected dovetail for the front. My uncle had a 552 that I think had this set-up. Can anyone with actual experience give a recommendation on replacement sights. I've been looking at some after-market Williams' sights, but I've never used them. Possible vendors for sights other than Williams: http://www.gunpartscorp.com/catalog/Products.aspx?catid=4309 http://www.gun-parts.com/peepsights/ Not sure I want to by-pass the original sight by putting on a peep on the receiver. http://www.tngunowners.com/forums/t...hts-for-older-remington-552-speedmaster-22lr/ Thanks in advance.
