Need some advice...I have a ruger m77. 30.06 with a Nikon scope. I have only used 165 gr(reloads) and 150 gr (factory) ammo. Problems is that with both I can group or link two shots then the next four to five are erratic.

Could it be the gun, the scope, or is the gun not liking the bullets and/or gr?

All screws are tight on the scope mount also....TIA

Consistently get the first two good every time?

Barrel getting too hot is my first guess

Scope mount is tight, but are the action screws?

What twist is the barrel?
Where did the reloads come from?
Barrel free floated?


A good easy thing to do, is to bed the action in the stock. A gunsmith can do it, but there are a bunch of videos of how to do it online.

Is your barrel over heating?

Its hard to say with any certainty without seeing and shooting the rifle (and even then it's guess work), but it sounds like it may be an issue with the barrel getting hot.

Send one down range. Put a LOT of effort into making a good shot. Get a good rest and take your time. Then go put the rifle in the truck with the AC going. Let it cool down. Then shoot the same way. That's where I would start. If it still acts up come back and we'll try something else.

I really really wanted to say this.

Never shot one that I would say was a "fine" rifle.

I wouldn't fool with the AC deal. Not worth it and if the barrel was scalded hot and the AC ice cold you could create some residual stresses in the steel.

Highly doubt it, but hell ya never know.

Yeah agreed. But it's still sounding like a heat issue. My guess is it's heating up then binding on the stock. Check to see if it stays floated or not. If not, problem solved. Float it. If it's not floated from the beginning then you never stood a chance in the first place.

I hear what you're saying and I respect your opinion, but that hasn't been my experience. In Louisiana heat, your barrel will never cool down enough after you start shooting without a little help. Comp shooters will actually cool their barrels with water. Then there's that whole water cooled machine gun thing.

M77 isn't floated unless OP floated it.

Have a Browning that was doing this. I just made a point in letting it cool well between shots.

I always thought, "damn that kid has good aim" I have trouble hitting the crapper, he's pissing in a radiator cap.

I think something is loose or something is touching the barrel.

How many rounds have you shot thru the bore? Is it broke in?

Could be the scope, take it off and put on a different rife, see if it groups.

Could be heat. Shoot one shot. Wait til tomorrow shoot again, etc see if it'll group. It'll take a while, but in reality that's how we shoot when we hunt. We shoot with a cold bore, one shot.

Are you flinching? Let someone else shoot it.

Honestly, I think the stock is touching the barrel. See if you can slide a dollar bill between the stock and barrel all the way to the action.
