Ruger m77 mark2 ***270 Winchester***?

Question

I have a Ruger M77 Mark2 s70 Winchester and the pattern is not all that great. Does anyone have any sugestions on how i could fix that??

Answer 1

I owned one of these exact rifles and found it to be very fussy on what ammo it liked. It hated anything Hornady (including relaods but loved 130Gr Remington Core-Lokts. Give these a try after you have checked all the basics the other contributers have suggested you do first.

Answer 2

First, make sure the stock's properly bolted to the action. If the screws are too loose, and sometimes even if the rear one is a bit too tight, it can mess you up. While your're at it, check the scope mount as well. If everything's screwed down tight, check for irregular contact of the forend on the barrel. If there is none, I'd bed it next (Accraglas is a pretty good and small investment), and if that doesn't work try free-floating the barrel. Also, consider whether it's really the rifle that's not shooting tight. A ragged trigger pull will pull you off, and a good trigger is a lot more fun to shoot with.

Answer 3

There are many possibilities.
Please take no offense to this list, for I do not know your shooting ability.
You must evaluate which may or may not be the problem or problems.


1- Faulty ammo, not all ammo shoot as well through all weapons.
Cheep or poor quality ammo is often the cause, some times to light of bullet or to heavy of bullet is used.
Different Bullet weights work at different rate of twist.
(I have an M77 Mark II in 223 that with 45 to 55 grain bullets cut 1 hole groups at 100 yards but try shooting a 62 grain bullet and I could no hit a target the size of door at the 100 yards 5 times out of 6 shots.)

Solution = Try several brands and bullet weights to see if it improves with one or more brands or weights.

2 Faulty equipment, defective weapon, defective scope, loose scope, loose scope mounts, copper or lead fouled barrel.
( if this weapon lets say was shooting good last week or month but just started shooting bad, I would say check your scope mounts to see if it is loose ether to the scope tube or rifle, if it is tight then your scope may well be broken.
Some times the vibration riding in a truck or car with out proper protection from a Padded gun case will destroy a scope, did the rifle get dropped or knocked off of something.
It don’t take much to brake just one side of a cross hair loose and it moves with every shot, all over the place.

Solution = tighten all mounting screws to the scope, try another scope if you have others, have the barrel looked at by a gunsmith for copper or lead fouling and cleaned if needed.


3- Poor shooting habits such as, Jerking the trigger, Flinching (from anticipating the recoil), breathing while shooting, poor shooting foundation these are just a few bad habits that affect accuracy.

Solution = shoot from a supported shooting rest or prone off bipods, don’t anticipate the shot let it surprise you.
don’t breath while shooting, take a breath and let out half and hold your breath while you pull the trigger.
don’t jerk the trigger, use only the tip of your index finger just in front of the first joint not behind the joint.
Then apply slow and steady pressure until it fires.

If this just started and you shoot other rifles fine then it would have to be either ammo or weapon as in gun or scope.

Answer 4

There are some things that could be affecting that. Maybe you are too shaky, afraid of the recoil after you squeeze the trigger, or your scope ( if you have one ), isn't that good. To improve on your grouping, try resting the rifle on a shooting bag and take a deep breath, let it half out, then shoot. If you are afraid of the recoil ( which I don't think you are afraid ), don't worry about tight grouping, just shoot at a really big target to get used to the kick. The last and final thing is the quality of you optics. Some scopes made today are terrible, such as a Tasco scope.

Answer 5

Check the simple things first; take a slip of paper and run it between the barrel and stock and see if it is floated all the way. A pressure point will move due to heat, cold,etc; and will give a lousy group. If you are using a scope dismount it and remount it using locktite to prevent any movement. Have somebody else who shoots put it through its paces to check for driver error. It will probably be some simple little thing.

Answer 6

Great rifle, good caliber...Are you using a scope? If so what brand? Iron sights ?Have you ever had a friend spot for you while shooting ? I can make a few suggestions, but need some more details to do it!
