I dial way off my point of aim and do not study the group until I'm done with that load. I used to burn them up if the first two were not touching just to get to the next load test. Only to find later it was a good load and I wasted the test because I pulled the first or second shot.

Just to say it, some years ago I was doing a lot of shooting (off a good solid bench) with my 220 Swift and new Douglas barrel. Wonderful shooting rifle and I was shooting a lot and doing a good job of it. Had some new Norma brass. I was shooting some very small 5 shot groups (under dime size). But every now and then when I'd do everything right, I'd still get the occasional flyer. Was reading a book on shooting one evening and the author mentioned marking questionable cases, making the point that every now and then there will be a bad case that weighing and measuring won't eliminate. He said to mark cases that throw flyers and if it keeps giving flyers, toss it on the ground. I started marking cases and found that I did have a couple that always gave flyers. Now, I'd like to tell you that I never again had a flyer, but you'd know I was lying.

If you are a really really good shooter with much trigger time and are on your game with a great rifle, you might at some point have a flyer that just flat should not be a flyer. If so, mark the case. Can't hurt.

Have an older Remington Mtn Rifle in 30-06 that does that. In my case it's something in the stock. 2 shots and the thin #1 sized pencil barrel starts touching. Trying to put 5 down the pipe at one time causes it to 'walk' up and slightly right. Each shot after the first 2 starts walking up and right. The 5th shot is usually 1.5" up and .5 " right.

Now I put 2 down the pipe and let the barrel cool off. Getting some great .6-.7" 5-shot groups.

Since it's a HUNTING rifle and not a target gun, I'm shooting cold bore for each shot of each 'string'. Once load-work is done I'll shoot a 3 shot group all at once and see what, if any, difference there is. There's usually some and sometimes there's a pretty good change (3/4 inch total) from first to third shot.

Today 300 win mag. 5 shots at 100.. getting better

Looks real good, I would be happy with that.
