I have been told that if you have the right info or a program that ihas this feature [evidently one of the reloading programs] that you can tell from the shape size and direction of "stringing" what you need to do or if you have the best you are going to get.
Could someone please give me some info on this. Lee
There are some old thumbrules about vertical stringing - need more powder, horizontal stringing - need less powder (or is it the other way around?)...? But I've never actually found those thumbrules to be useful. Starting on the low end of your acceptable powder charge, then slowly increasing the charge (in small increments within safe limits) until you find the sweet spot is pretty much an unavoidable exercise. Consistent stringing problems would indicate poor bedding or technique (or a bad barrel).
You can get upward vertical stringing as a barrel gets more fouled it builds more pressure and you see second or third shots ect. higher on the target.
If you swab between shots using the same powder charge this should not happen.
It adds a lot more time to your range sessions, but try not to shoot long strings of fire. Walking may be something else, but if you have already worked out your best load for accuracy and you are keeping your barrel swabed and clear,it usually is either the barrel heating up and flexing, or a combination of barrel heating and stock bedding depending on the type of weapon you are fireing. It's not the easiest thing to do either in warmer weather or areas, but try to let the barrel cool down between shots. Shoot a few. 3 at most, then let it sit for several minutes to cool before shooting again. (why we usually sight in a new rifle in colder times of year, shot 3, let it sit for 5 min, shot 3, so on. For some makers, their rifles seem to walk shots as the barrel heats up as you shoot several shots in sucession)

i was at range .a guy came up with a .243 rem bolt action rifle. he had it special made.it had a hart barrel.they make great barrels. this gun cost him 2,000 dollars. he sat down,laid gun out, and shot. that gun shot every bullet in a half moon at 100 yds. he was pissed.i then took out my 250-3000 sav. lever action, 87 gr bullet.this gun was 80 years old given to me by my dad.he killed many deer with it in the depression.i sat down, shoot and put all bullets touching holes at 100 yards. he was then really pissed. ha,but life moves on.

out of 5 shots I am getting 1 that goes 1/2 inch higher than the rest the other 4 will be 2 and 2 over lappind with about a 1/4 inch between

some times the bottom 4 move around abit but they are ok its that top one that takes the group over an inch some times. Lee
Pittsburghunters suggestion that fouling is increasing pressures leading to the higher print is where I'd lean. Is the high shot always the 5th? Does it have noticeably more recoil?
I assume these are 100 yard groupings. They are "darn" good already, you can lend them to me any time you want .
I clean every shot to see if that made any differance it still shoots the same;I normally wipe between shots even though I shot APP.The SW will tear a ragged hole but they are kind of expensive to shoot for fun I do use them for hunting,I read where the XTP are the same with out the plastic tip if they are I must be doing something to cause that flyer.

Because the stray is always high, i would lean towards it being just a velocity variation. Maybe something to do with the sabot/bullet/bore fit. Just enough to lift it. Is the figure below a typical pattern?
How to read groups,help
