I had a chance to shoot a LTR at a 100 m gong. No, not very challenging but fun nevertheless...
It was visually tough for me to get over the large troughs milled into the barrel but I found a rifle with a 20" fluted barrel is a delight to handle. Eventhough Remington rifle stocks don't fit me very well, I think I would be a satisfied owner of a LTR.
I have recently heard the LTR is discontinued due to problems with feeding and the magazine. I also heard of a slightly different LTR, called I think, the Tactical Light Tactical Rifle- a 20" non fluted barrel with standard BDL bottom metal... anyone else?
Lastly Mike, I noticed your stainless Remington BDL DM in .308 for sale on this site. You have the basis for a most excellent rifle. Throw the DM stock away and get a McMillan. Order some BDL internal short action magazine parts and bottom metal in SS from Remington, and have one of the premium barrel makers screw on a stainless 20" fluted barrel. Heavy matte bead blast the whole thing dark grey and top it off with a Leupold Long Range 4.5-14x 50mm scope. This should take care of anything within 300 yards of you or farther.
