RE: 5th Caliber opinion: The .22 rimfires.
I also really like the 22 rim fires a LOT. It sure is great to beable to shoot so much, so cheaply, and NOT have to reload it to do so!!!
Lately i've been shooting my LH Remington 541-S with a 2x6 Williams scope, and it's a joy to shoot something so accurate and fun to shoot!!
For pest control, i need a bit more power because of the possible longer ranges, so it's my 597M with a 7.5X scope that gets the most use.
I couldn't live with out a few good rim fires around!!!
