SingleMagazine fed? Or single feeding?
The simplest answer is to shoot 4-shot groups.
When you observe this behavior, the most difficult thing, IMO, is to decide whether the flier was caused by you, or the load itself. There are various ways to reach a conclusion such as simply firing lots of groups, recording which shot number was out (i.e. random fliers are probably the load, the first or last shot of the group being out consistently may well be the shooter), etc. Look carefully at the statistics and you can usually make a good estimate of whether it's the load or the shooter. If you decide the load is at fault, seating depth testing can often get it dialed back in. If the bullet design/manufacture itself is the cause, no amount of load tweaking will likely fix the problem and switching to a different brand or type of bullet may be the only way to correct the issue.
This:Getting 4 shot in one ragged hole then throwing one shot out to left. Any suggestions.
I see lots of novice shooters look for the fall of each shot and often in so much of a hurry it affects good follow through procedure.try shooting the groups and have POI where you can't see the group. Or if using Etarget don't look at screen to see groups forming.
Was the shot off to the left the cold bore shot?
If you're not using wind flags, get some. They don't have to be elaborate. You will be surprised how much wind is out there that you don't notice...but your bullet does!
I see people say that "they" caused the flyer. I am always puzzled by this. When shooting from a bench I never cause a flier. It's always the load at closer range, and at longer range its the load and/or conditions.
You’re better then me. I screw up shots at the bench all the time.

EXACTLY!^ my thoughts too. I spend a lot of time thinking about and trying to manage my "bench manners" and every match I shoot I realize I still have room to improve in that area. While I prefer long range benchrest, I appreciate my few years in short range BR because it really opened my eyes to the role of "bag handling" in consistently shooting good groups and more importantly good aggregates.
Take a Piece of paper & plot each shot, determine which # shot is off. as dusty said, if it is 5th shot, probably shooter error,can also mark case from flier & check case later at home for differences,may need to cull that caseGetting 4 shot in one ragged hole then throwing one shot out to left. Any suggestions.
