Thread: Grouping problem 338LM

Any developments on your issue Red?

Going to take it apart tomorrow and check recoil lug thingy and give it the once over for any shiny marks anywhere.

I did get a half turn on the front rail mount and 1/4 on the rear, but just put that down to settling in with everything being new. Don't think it would have caused the problem.

The Norma cases are coming up to x3 reloads with no issues as yet, which is pleasing, and haven't had any pressure signs either. The speeds for my loads are consistent with internet data. So, considering all things it's looking like a mechanical problem right enough, as has been pointed out.

I'll be paying closer attention to body position, and swap shooters to see where the problem emerges or goes away.

If it's still there at the next shoot it'll be a bedding job.

Thanks for the interest folks, I'll keep ya posted. . . .

Came home early from hunt due to snow so could pop over if you feel like a range day

Ok, some interesting results today with Horihunters help. Groups were shot in the order of the circled numbers.

Hori is a leftie, so bear in mind for his groups the rifle was moved to a totally different position.




Then at home when the rifle was dismantled found this. . . .


So, you can see the fluting marks on the lower part of the barrel channel, and the rubbing on the side about 5" long. The marks are more apparent on the channel than the barrel, as you can see only a light mark on the barrel.

Next question is, is this enough evidence to cause problems ?

Looks like you've found the problem

Good grouping Hori on the 2nd photo

Well, thought all my troubles were over after the channel discoveries, but oooohhhh no, just beginning !

Loaded up and ready to go, fired first 2 shots, went where I expected them, first high(cold barrel etc. ) next through the centre of the bull Wahooo !

Next 3 all over the clock out to 4+" (100m), WTF !

Ah well must have been me, too quick too keen

Try at 200m, well f#*k me, over 8" all over the place, bollox. . . . . . pack up go home, contemplate taking up full contact tiddly winks. . . .

Next morn pick up rifle, scope and rail nearly fall off

Off to Gunworks tomorrow for rectification.

The shooting Gods are obviously pissed off with me

Bugger! Surely it will be sweet when thats fixed.

It's a Savage right ? This is the second
time I've heard of this happening? First time was at a F Class shoot.
I'd be getting out the epoxy as well as the allen keys.
I hope you get it sorted.

RUNAS

Looks like it was Loctited on instead of epoxy, so new good quality rail ordered and going on properly. Also one of KG's Terminator T3's on it's way.

Looking fwd to the next round of the saga

As am I....Haha
