old single shots
Member Posts: 3,594
I have 2 different loads with 2 different powders that will put 4 out of 5 shots in a 1/4" ragged hole. 1 shot out of the 5 will always go out to the left (9 oclock) about 1/4---3/8" It may be the 2nd 3rd or 4th shot that strays.The other 4 will group 1/4" regularly.What is causeing this?? Caliber is 223.It also does this with 2 different bullets.

Real Men use a SINGLE-SHOT!
How long do you wait between shots? Do you let the barrel cool? People always say 3 shots groups to test the load, 5 shot groups to test the shooter.
I always use 5 shot groups for load testing. 3 shots don't tell you much. If you are shooting all 5 in a quick string barrel heat can cause the bullet to move.
Also lets say you shoot 4 shots, chamber and barrel is heated up. You chamber round number 5 and wait long enough, the temp change between round 1 and 5 will be enough to move that shot up. 20 degree will move bullet impact almost 1MOA in my gun. I always leave the bolt open and do not load a round before I am going to fire. Keep the ammo temp as even as you can.

2. measure each case
3. weigh each tip
4, measure each tip
5. weigh each loaded round
6. measure each loaded round
7. fire each shot at the same amount of time between shots
8. look in mirror if shots differ
Its really hard to soar with the Eagles, when you are stuck with turkeys!
why chase the game when the bullet can get em from here?....
Got Balistics?
also, how many firings on the brass? Have the necks thickened and caused a change in neck tension in some cases more than others? (check neck wall thickness on the flyer cases). Have you tried marking the flyer cases and then loading them and firing a group with just them? Have the cases stretched so that they contact the leade on some of the cases and actually start a crimp on the bullet? (shiny area on the case mouth or whole case mouth shiny from the bolt forcing it against the leade/rifling)
