As for the ammo, I fired a variety. Some was just cheap stuff, which is the bulk of the .22LR ammo that I have. Some was more expensive but nothing of the high end target type ammo used by competition shooters. Ammo types I shot were: CCI Blazer, CCI Mini Mag, Federal's American Eagle, Federal Champion (target velocity), Remington Thunderbolt. Nothing special as far as .22LR ammo goes, some of it even considered to be pretty low end - the CCI Blazer and the Remington Thunderbolt. There can be some surprises though when you expect something to be junk and it isn't. A look at the targets will show you what I mean. Click on each to enlarge it. They are annotated to show which ammo was used on each bull's eye, and as to group size. All groups were 5 shots except for one in which I fired 4 because I made a mistake when I loaded the mag, and the other because I ran out of ammo - so I discounted both of them. As for measurment of group size, I measured the widest spread from the outside rim of one to the oputside rim of the other. I think that is not the proper way to do it
and that normally you would measure from the inside edge of one shot to the outside edge of the other. That would have been tough since the groups were pretty tight. It was just easier to measure the way I did it but had I done it the right way then the group sizes would have been a bit smaller, maybe by as much as 2/16" for some groups.
Looking at the first target, you can see that every shot is to the left of center. I probably had not fired this rifle for at least a year, maybe as many as 2 or 3 years, prior to today and do not recall if it was sighted in right before or not. It is possible that the sights got messed up during a cleaning or moving or rearranging of the gun locker. Whether or not it was shooting at the center of the target is inconsequential for all the shots on that target. The thing was that it was shooting pretty consistent groups and all groups were to the left. That was good. A bit of twiddling with the sights and the result was target 2 where many more shots are at center of the bull's eyes. The groups on the second target are not too shabby but I could not again achieve the best two groups on target 1 which were only 6/16" across each.
When I was shooting on the second target, I
By the way, yes it is pretty stressing to try to shoot as well as you can when hand holding an 8 to 9 pound rifle even if resting on the bench. Maybe I should invest in some shooting bags or a rifle rest. I suppose that working out a bit to better develop my arm muscles might also help, heaven knows I have not worked out recently because of Arthur I. Tispain. No excuses though, and heck I don't need any, I shot pretty good for a muddled minded middle aged guy whose eyes are not what they once were back in my day. In closing, I have to say that the Remington 513T Matchmaster is one heck of a tack shooter and is obviously capable of better accuracy than it can get with my finger on the trigger.
All the best,
