Check for loose rings or mounts. Also watch your bench technique you may have had 2 different pressures on the rifle in the 6 shot group. Down pressure and rifle placement can affect groups I this manner.
? Stock weld / cheek weld changes ? Bench rest technique different on different strings of fire? Scope and / or mounting issues?
A lot of magazine rifles will do this - vertical change or stringing - it takes three or four shots and a bit of a pause to warm them up - once the impact point changes if you keep shooting they will hold a good group - others will do it walking up the target with each shot - the tube magazine tied to the barrel is key to it. Paco Kelleys lever gun forum covered this several years ago - may not be your problem but its the first suspect with a long magazine lever rifle . If its a single shot and you are resting the barrel - I bet you moved it back or forward on the rest between the two groups .Quote:

Will go through and check all usual tube fed issues.
Yep, vertical stringing is something I learned about with an old 30-30 (Marlin 336 type) many years ago. If I shot 5 shots fairly fast, all 5 shots would string vertically. By shooting one shot into ground, then spacing next 5 shots 1 minute apart, that old 30-30 could hold 1 MOA at 100 yds pretty good with cast bullets.
What distance ? Iv'e seen groups like this with bolt guns and it was caused by parallax in the scope.
Is this something that recently started with the rifle?
