200yd group test

[kroppr77]

Today I ran an 18 shot group at 200 yds at 4inches. It was off a bag, on a bench, flat range, calm conditions. I was doing this test because I’ve had lots of troubles with this rifle. This was the last test to see if I trade it in.
I have a Christensen 300wm for example that can shoot MOA or even slightly sub MOA at 200 in 5 shot groups. Which feels hard with this gun, and is disappointing considering the Christensen was a fraction of the cost.

For some rifle information, it’s a 6.5 prc I had built about 2 yrs ago. I have not ran tons of ammo through it as I haven’t enjoyed the shooting. There is a 16 inch barrel on it(I didn’t know better at the time, I was told to get this by the gunsmith), and it is shooting factory ammo. I have shot ELDM 147, ELDX 143, nosler accubonds, and some Berger 144. It seems to like the ELDM the best, which is what I’d prefer, and is what was used in the test above. 18 shots is a large test I know, and obviously there was better sub groups from the 18. In a real world, large group size, this may be the norm? Anyways I’m doing this to see if shooting this gun is feasible at 500 and in. I don’t think I’ll bother re-barreling it if I move on. I will go a stock tika route.

Not acceptable

4" at 200y will be 10" at 500y from a bench, likely bigger than that from field positions.

For science purposes, try shooting a cold bore shot, plus 3 more. Repeat this test at 4 different aim point at same distance. See if the rifle aggs together for a tighter cone of fire. It likely won't, but possibly. There could be a lot of contributing factors affecting the accuracy. Are groups mostly vertical, horizontal or just big shotgun pattern?

In the interest of learning, what would the different causes be for vertical, horizontal, shotgun?
Vertical pattern = causes
Horizontal pattern = causes
Shotgun….

What do the 100-yard groups look like?

Can you post a picture of the group?

What does this rifle weigh?

Is it suppressed? An unsuppressed 16” 6.5 PRC sounds very unpleasant to shoot. A 16” 6.5 PRC with a 6” or 7” suppressor on the end sounds much more pleasant.

The group was 4 inches horizontally and about 2 1/2 inches vertically. Slightly tighter vertically than horizontal.

It is not suppressed, just has a brake. I didn’t take any pictures, just measured for reference. The weight is a little over 7lbs, so it’s not like it’s crazy light for the size.
Judging off the fact that it has shot 4 different factory ammo selections like crap, I take it this gun is junk.

A 7# 16” 6.5 PRC with a brake sounds horrible to shoot.

I think you need to try it with a suppressor before you decide it is junk.
