I am struggling with a load for a 300 WSM A-Bolt. So far it likes 200 grain accubonds but there is always a flyer. I have found a load that I can shoot a group of three shots. The first shot is perfect, second shot is 1" to the right, 3rd shot is touching the hole of the first shot. It does this consistantly. Would this do to the barrel heating up after the first shot?
If thats what its really doing, then those groups are not bad.
A-Bolts have thin barrels. And they are light and you are shooting a higher performance round. If I was you, I would be pretty happy with 1MOA groups with a 200gr load.
But to answer the question, several things.My defintion of fliers is little different. It an outlier, 2 Std deviations away from the group. And a group needs really 5 shots at least. You stats folks know what I am talking about.
A-Bolts are great guns but the factory glass bed sucks. Its easy to redo. Thierglass bedlooks like a globof bubblegum.I also doing likeaction screws to be slotted. Ican putconsistent torque on allen screw heads with a torquewrench.
I have a abolt right now that needsrebedded. It will shoot 2 shots great, but3-5 bad. I get 1.2 MOA but where I use it, it doesn't shoot bad enough for me tomake time to rebed.
Second, maybe ammo. Has any ammo done well with it? Any factory ammo.Bullet runout, is a culprit I findwith alot ofreloaders fliers.
