Why do I shoot so many 1 shot flier groups ?

Three shot groups with one shot away from the other two tell you very little. A good 3 shot group may be telling you something about how the rifle shoots . A 3 shot group with one away from other two may well be telling you that is the actual group size of group the rifle shoots.
 
There are so many things

that can be wrong to make big cloverleafs= big groups a list develops. First I suggest choosing a seating depth you think may work and adjust your load to try to tighten the group up. It that doesn't help, try different bullets and or powder. I would be surprised to see a big boomer shoot groups like most benchrest folks are use to seeing unless the boomer is a Long Distance rifle made to shoot 600 yds and over.
 
shooter

ive been to a couple of b/r shoots and those guys know how to shoot granted its not anything like h/power but what these guys can do goes past my feeble understanding.

i know one champion shooter shot 11 cases of ely bl. lable r/f ammo last year in practice. so nothig is cheap is it.


i am shooting a martini mark 5 right now it really doesnt have a b/r forend on it so i am having problems with the rifle moving around after shooting and recocking the rifle.

i purchased a sinclair forend rest for my pappas rest and am using a protecktor nr. 1 bag in it but i just cant get that rifle to stay leavel and its an effort to keep it leval.

is this a problme someone of you long time shooters shooting off a bench have experienced if so please tell me what you do to resolve this.

all answers and critizems cheerfully accepted.

thanks

I hadn't been shooting much, other than deer season. I built a rifle and took it to the range to shoot it. it wouldn't group well. I took it home and tweaked it. Went back and had little improvement. This time I had a man with me who has been a competitive shooter for 50 years. After I got done shooting and was complaining about the rifle he gave me a list of things I was doing wrong, personally. I worked on those things and the rifle started to group nicely. I hadn't been shooting seriously for 20 years and had picked up some bad habbits.
 
list

would you be so kind as share the list. i for one would like to see it.

thanks

Marine Sniper has already said he found the problem. This all to commonly happens with calibers larger than 6mm or more powder, why, I'm not sure but all my larger caliber guns shoot better with a little more clearance around the neck. As far as fliers. Once a person gets enough competition experience, with groups forming on the target, you can tell there is something wrong even though the group isn't bad, it's fixing it before it goes bad that seperates the great shooters. Talking to a couple of Hall of Famers at the shamrock, one thing they pointed out is they watch for a half a bullet movement that they can't account for. That's a flier to them.

I will post pictures of targets of a recent test session at 600, 1000 and 1212 yards.

If I remember right the groups (3 shot) were in the area of

600-1st group 4-5 inches
600-2nd group 1.75 inches
Pretty bad mirage at 600

1000- 1st group 4-5 inches
1000- 2nd group bout the same

1212-1 approx 5 inches
1212-2 13 inches (held the rifle too loose)
1212 3- right around 3 inches.

These are all the groups I shot, not a few cherry picked ones. All were also shot across an open hay field with no wind flags. For a 15 pound 300 Weatherby hunting / tactical rifle I am very satisfied.

one thing i might add is when your clearance is tight you will get fliers , when this happens you will see pressure spikes that causes this ,so if you didnt tweek the case that shot the flier then what really happened is your neck tension bit you. like greg said .003 is much better for accuracy particularly for the mags , but with light neck tension them fliers are going to come back i can promise you .hope this helps. tim in tx
 
My necks are .011 with .0025 tension. .001-.002 RU on the bullet.
 
CWOP, I just saw your request for the list. I should have said "He enumerated a number of things I was doing wrong". Body position, trigger finger position, cheek weld, breathing, etc. we worked on them at the time (several years ago). I never wrote them down. But, essentially, I was in a different position relative to the scope and rifle every shot, and using poor trigger and breathing techniques also.
