Long range groups

I wanted to test my SAKO TRG22 in 308win at long range and got an average 7,5cm groups at 600m or 3 inches at 660 yards.
I whould like to know what other precision rifles are grouping at that range for comparison.

Thank you.

Please publish the load you used to get such a performance!! [Confused]

The load was a moly coated 167gr Lapua scenar, 44grs of N140, Rem cases and cci primer.

1/2 MOA groups at longer range are not uncommon but not terribly common either. For me it's difficult to find a good weather day and a desire to shoot groups. I recently shot to 500 yards for a demonstration of sorts and have groups at 100, 200 and 400 yards that are about .5 MOA.

Here's the group sizes to 500 yards.

code:

yards   1 MOA   1/2 MOA Group   Group MOA
___________________________________________
100	1.047	0.5235	0.494	0.471
200	2.094	1.047	0.978	0.467
300	3.141	1.5705	3.13	0.996
400	4.188	2.094	2.108	0.503
500	5.235	2.6175	5.299	1.012

Your group at 600 meters is pretty good shooting...I'd say the rifle and load are keepers and you've obviously practiced a bit somewhere along the line. Was this shot from the Parker Hale bipod or another type rest?

Outstanding accuracy. You must have caught a windless day. Even the best of "winddopers" would have difficulty getting that kind of group with a bit of a breeze to contend with. At the longer ranges, wind becomes much more of a factor than trajectory in making consistent hits.

It was with a benchrest. With the muzzlebrake and the bipod innstalled it kicks very little.
There was a small steady wind. This rifle usually shots one hole groups out to 200m.

The Sako TRG are nice rifles... I've shot the 41 (in 338 Lapua) and shot with a fella using 21 (308 Win - 7.62 NATO). There was a 42 for sale a while back but I don't need another 338 Lapua. Very nice rifles, pricey but quality...very nice trigger system. The optical quick release mount system on the 41 had a little trouble as I recall when using a left side parallax adjustment scope.

What you using the rifle for, work or sporting? I'd guess sporting if you're building custom ammo.

Great shooting.

For comparison this morning I shot 2 4-4 1/4" groups at 620 yards. My rifle is also a .308 but with a custom barrel on a Winchester 70 action. It's preferred load thus far is 45grs. of Varget sparked with a Fed 210M pushing the 168 Sierra in Fed match brass. Hodgdon calls for 46 grains as max, but my rifle builds pressure rather early and I had to quit at 45.

It seems to me that the limiting issues at 600 or greater are more to do with optics and bench equipment. I have a Leupold 6.5-20 on the M 70 and I think I could use a bit more. Also, my bench for shooting 600 isn't quite as sturdy as my 200 yd. setup. I'm finding it takes absolute mastery of the details to be successful at 600 let alone further. The rifle seems to be capable of 2" or slightly better, but the rest of the systems are not quite yet ready. Operator included. [Big Grin]

TRG, your results are noteworthy. But, frankly, I'm not surprised.

A couple of years ago a friend allowed me to try his TRG-22 .308 at 200 metres on the range. The first four shots essentially went into one large hole and I got cocky. I pulled the fifth and final shot about half an inch away from the other group. So with the "opened-up" group, I was getting essentially 1/4 minute of angle. That's almost unbelievable for an off-the-shelf rifle.

By the way, the load you're using sounds about ideal.
