mannyrock,
I went to the range yesterday to get my hunting rifles ready for the upcoming deer season. One of the rifles I shot at the range was the old style Ruger 44 Mag carbine. I have yet to use it for deer hunting but I wanted to see how this rifle would shoot, using your advice (with a slight modification made) about not overtightening the front barrel band/screw.
What I did was cut a small piece of garage door rubber edging (sold I believe at Home Depot & Lowe's in 16' or so rolls). I then tried to install this in the elevated bottom portion of the forearm where the gas block sits. However, I coud not get the barrel band on, so I cut the rubber edging thickness in half and tried again. This time it worked, though the barrel band had to be moderately forced onto the stock & barrel. I figured the rubber material would give some, allowing for a slightly looser fit (which it did). I then just tightened the barrel band screw until it was just screwed in couple of turne into the open end of the barrel band. As you might imagine, the swivel stud moved freely, so I put some black electrician's tape on it to silence any noise it made.
Since the carbine was already sighted in from last year, I shot a 3-shot group at 100 yards with the ammo that had been the most accurate (ie, Winchester Partition Gold w/250 gr bullet). In the past, I had shot 3-shot groups at 100 yards with the the average group consistently between 3"-4", either with vertical stringing (when rapid firing) to a triangle shaped group (when letting the barrel cool between shots). The weather yesterday was mild with the temperature in the mid-60's. I shot a 3-shot group with the barrel cooling for 10 minutes between each shot. The barrel was cool to the touch for each of the subsequent shots. I only shot 1 each 3-shot group, as I had 3 other rifles to sight-in and I wanted to get back home in time to catch most of the New Orleans Saint's game. The group was just a tad over 2" with the 2nd & 3rd shots within 1/2" of each other near the bull's eye. The 1st shot was the farthest and highest of the 3 shots, which I can't explain why the 1st shot would be the highest, though it's possible it can be attributed to operator error. Though this is only 1 each 3-shot group and means nothing statistically, I have never achieved such a good group from this carbine (or from the newer Ruger 99/44 Deerfield carbine when I owned it), even when taking my good old time to sight-in. So, I'm encouraged by the first group, using your advice. I know that, if I ever do deer hunt with it, the difference between a 2" group vs a 3"-4" group is meaningless at the distances I will be shooting. However, it's always good to attempt to better the accuracy of a rifle.
Thanks again for the tip.
