Thank you TKacook and nothernug for your help and knowledge. I have a great many "custom rifles" but my M48 has become one of my favorites..I have to admit that when I say I like to keep this M48 close to original, my friends would laugh as I really "Experiment" and make small changes to give me a "one of a Kind" look and a weapon that I enjoy shooting! I dislike a metal butt plate especially when I am at the range with several rifles and I am going to fire 150 to 200 rounds. So my m48 has a nice rubber Butt pad! I also have a quick release Scope mount and a small 4 power luepold scope on my M48. I dislike a rear sight that does not have windage adjustment ! So, I mounted an old 1894 (I believe) Krag sight right where the original sight was mounted. I needed to enlarge the wood opening a little and put a round file to lower the wooden groove.. Viola, It works very well, This old sight even has a small PEEP that can be raised up from the back.. The peep sight hole was so small I opened it up just a hair so my old eyes could see through it.. The open sights are excellent to 100 meters and using the peep, most bullets are kept in a six inch circle at 200.. Using a bench and sand bags of course! Now to upset a few, with my new barrel, I beleive I may change the caliber to 8mm 06.. Since I reload for all my rifles, I know that the ballistics are a huge improvement up to 175 grain sp. bullet..Nothing wrong with an 8mm. I kept my persian 8mm (for now)... anyway, this is the way I enjoy my guns and shooting..I estimate that I shoot about 500 or more rounds a month (sometimes way more) and I kill and wound a lot of paper! Today we had to call a ceased fire at the range to let a small doe walk accross the 100 meter target area. She even stop to graze a little.. Poor thing got to be deaf or has grown up on the range and has no fear of rifle fire... I have not hunted since leaving SE Asia in the 60's and looking at that little doe made me happy I don't hunt ! Not that I would not like to take a bear or moose someday before I die but I could not shoot a small doe that will walk onto a firing range to graze while 10 or more people were shooting! Well, enough for now, again thanks for your help..
