243 Win Help Neede

Help am shooting a Ruger 243 with winchester brass and nosler 100 partions. Scope is a 3x9. Off sandbags the best group at 50 yards is about 1 1/2 inches. What is the problem?

I would try different bullets. Of all the rifles I own, none of them will shoot nosler partitions very good.

1. Check scope rings, bases, and screws holding action to the stock to make sure all is snug.
2. Have another shooter fire a group and compare.
3. Let barrel cool between shots.
4. Try a box of factory ammo and/or a different handload.
5. Try a different scope.
6. Float the barrel.
7. Glass bed the action and barrel.
8. Lighten the trigger pull.
9. Make sure your rest is rock solid.
If all else fails, either trade it or live with it. I bet with a little trial and error, you can get your groups down to around MOA or better. Good luck!

try an 80 grain bullet just to see what they do. My .243 would not shoot 100 grain bullets worth a crap.

How are you resting the gun on the sandbags. Some rifles are sensitive when it comes to how they are rested. If there is very little space between the forend and the barrel, resting the forend on the far side of the sling stud can cause them to contact and throw groups into the toilet. I had a Remington Model 7 that was notorious for this. Try putting the front rest as close to the action as possible.
Also, how hot are these loads? My Tikka .243 likes them hot for the 100 grain bullets. Not "blow-out-the-primer" hot, but hot.

Back off to 100yd, and see if it get's any better IE less than 3MOA.
Yes, it's possible to get better groups (in MOA) at longer distances.

1MOA = .25" @ 25yd, .5" @ 50 yd, 1" @ 100yd, 2" @ 200yd etc

You never did say what Ruger you are shooting them out of. A 77, a 77MKII or a #1. I have a 77MKII stainless that will pound nails at 100 yards. To eliminate loads, try anything in the Winchester Ballistic Silver Tip line. If it is a bolt action, check scope and the bases and rings first. Then PILLAR bed the action, and free float the barrel, and do a trigger job. Make sure the action lug bolts are torqued to 35 inch pounds.

Reloads or Factory Ammo?? Are you using the recomended C.O.L. or are you seating the bullet farther out of the case to contact the lands? Are you crimping your reloads

What is it you desire? the most accurate rifle possible? then do some if not most of the steps already suggested, if you just want a better shooting rifle than what came in the box spend a little money on reloading equipment and most of your problems will go away

The problem may simply be paralax in the scope. Most highpower rifle scopes are designed to be paralax free at 100 yards. Try leaving the rifle still and move your eye from side to side while aiming through the scope at a 50 yd range. If the crosshairs seem to move across the target as you move then you have a paralax problem.
