Pioneer2 - This is the 18 1/2in. ported barrel model. It has the Ballard cut rifling. I am trying to stay with open sights. At 60 my eyesight is not as keen as it once was, so about 100 yards is my limit.I had not taken heart to the rifle until aobut 3 years ago. It is just do handy in the tree stand. It's loud as all get out, but has done fone so far. I killed a few deer with the Remingon factoy loads. I bought some stuff from a small maker out of Georgia and it was a ton better as far as penetration and the drop was a bunch less, i.e. the muzle velocity has to be a ton faster.It uses a 270 gr. Hornady bullet. I got my hands on a bunch of once fired brass and am reloading. I have made about 25 rounds so far trying to get the recipe just right.I've been using the Speer Gold Dot bullet. I think I have done about all I care to as far as looking for a good grouping combo. I plan on hunting hogs on a friends land sometime in August. Maybe I'll get some pork.
