Why is it only now that I decided to try precision shooting? It is so much fun! I bought this rifle last month and took it to the range for the first time last weekend. It is a Thompson/Center LRR 6.5CM and I mounted a 5-25 Vortex Strike Eagle on it.  Last weekend I zeroed the scope at 25 yards because the 100 was kinda crowded and had it sub moa all day and I really enjoyed it.  Yesterday I went to the 100 yard range and it still did well but was more like 1.5 moa with Sellier&Bellot 140gr. I did have a couple of sub moa groups though and so I think that is more me than the rifle, ammo or scope.

I think for now I just need to work on my own skill set with it but dang is it a ton of fun! I just wonder why I didn't get into this sooner?

You might want to investigate snipershide for lots and LOTS of information about precision rifle shooting.

It really gets fun when you start stretching out the distance.

Consider this a free LR lesson.

MOA, or minute of angle, is a method of measuring an angle. In shooting terms, an MOA is a cone where the tip of the cone begins at the muzzle and the base of the cone extends from there. MOA is generally discussed at known distances, ergo 1 MOA is a touch over 1 inch in diamter at 100 yards.

1 MOA at 200 yards however is 2 inches in diameter, as the the farther that cone extendes, the wider the base gets.
1 MOA at 25 yards would be 1/4 of the diamter of an MOA at 100 yards, that is to say the diameter of the cone at 25y would be 1/4in.
At 50 yards the base of that cone is 1/2 the diameter that it would be at 100y, or 1 MOA is equal to .5in @ 50 yards.

So a 1in group at 50 yards would be 2 MOA. A 1in group at 25y would be 4 MOA.

Enjoy the addiction!!


I’d suggest trying Hornady 140eld, Hornady american gunner 140’s and Federal Gold Medal 130’s or other match ammo (Berger/Prime). They should do much better than the S&B.

Also, you may want to space out your rings differently. Sometimes you can bind up the parallax or erector by having the rings directly adjacent to the turret.

Yeah, I thought I'd start with the S&B because I bought quite a bit of it. But I also have 200 rounds of Hornady 140gr ELD match I haven't tried yet. Should I switch to that maybe?  I also have some Federa; American Eagle 123gr match too. I don't intend to upgrade anything else for now. I really like the rifle and scope so far.  As I mentioned, I really feel like my biggest issue is that I need to just use it and get even more comfortable with it.

Yeah I just signed up there recently.  Great info!

Good point and I was thinking the same thing.  Parallax seems to be ok but I don't like that it is mounted that close to turret either and besides, I also want to re-zero it at 100 yd anyway. I originally did it at 25 out of convenience.

Well said
