Rough day with the MTR



Log in to see fewer ads
Went to the range yesterday and shot well. Nine groups in order of best to worst were: .109, .136, .228, .255, .259, .278, .335, .357, .475.
I am not new to shooting, but am still learning .22 from a bench, and expect most of the deviation is on me.
Today, I wanted to try some different torque settings on the action. The problem seemed to be the best groups were at the original setting of 23 “ lbs, and at 17 and 18 “ lbs, but each of the groups were basically 4 in a low .100” group, but 1 out another .100”.
I’m not sure how to use the information gathered, because I am not sure what is me, the ammo, or the fact that I cleaned the bore and chamber last night. I did fire 10 shots to season the barrel, and the warming group tightened after the first 2 shots.
All shots both days were at 50 yards, at PHA range, and there was no wind, and temps in the high 80’s.
At this point I am confused about the “flyers”, and the fact that it did well at 17, 18, and 23 “ lbs. but stunk everywhere in between those?
Anyone have suggestions or experience with this?
Everything I have learned has come from this site, so I have confidence in your replies.

Are you using any wind indicators?

There's always going to be a flier.

You should have your scope set so POA is different that your POI so as not to obliterate the POA. Ten-15 clicks high.

And you're worried? Best advice I can give to you is.., stop messing with the gun.

Thanks.
No wind flags, but it was dead calm.
I used one inch orange dots with a center point and cross hairs on them, and relied on lining up my cross hairs with the cross hairs on the target. I will use your suggestion on setting my POI separate from my POA.
I guess I need to shoot some more groups between 17 and 23 " lbs. and see if one setting starts to stand out?
Should I try it with other ammo. or just the lot # of SK rifle match that was shooting well in it?

I'd try some other ammo but it's doing awfully well as it, I was shooting yesterday afternoon and the heat definitely was getting to me.

And mix up the settings on the action screws. 17 in-lb front-20 rear, etc., etc.

I would say to STOP screwing with the torque settings. Think about it, The reason changes to the torque settings changes POI and group size is because the action is not bedded evenly and there are high and low points. Changing the torque settings creates tension on the action - like pivot pointq. Your rifle - MTR - should be pillar bedded so that there is no pressure on the action, hence no need to torgue. just snug it up and and forget it --- or bed the action so that there are no high/low pivot/pressure points.

Wink Not always!

Mine has the front pillar machined slightly lower than some of the surrounding wood! I made a Stainless Steel shim to allow the pillar to function correctly. Fixed it right up!

If you do change torque settings on action screws, try to shoot one group for gee whiz, then shoot next few groups to see actual affects.

You could be getting tired as you shoot. It is very tiring to shoot real well form/trigger control wise. All your breathing being regulated can take some toll too.

Some times there can be some psychological affect too, you know you altered something on rifle. It gets in your head.

Put her back on 23” pounds and shoot for a while. See your overall results. Get a bigger sample multiple outings.
If you change torque. Repeat.

You should see a pattern develop.

Also, 10 shots may not be enough to season a barrel. Some barrels need as many as 35 if you can believe this.
This is something you should experiment with. See what your gun seems to need. Using xxx ammo after good cleaning.
And maybe see what it takes to season barrel after mediocre cleaning.

Your results seem good.

Cheers.

I know. We are always looking for better. Sometimes we are infact already at peak best setup wise.

And a good reason to shoot free recoil if your set-up lets you.

I’ve been hesitant to do that because of the cast off on the MTR stock.
It is however, on my mind.
I recently picked up a Bald Eagle front rest and bunny ears Protektor rear bag for that purpose. I have done everything I have read about and can think of, to get the setup the way I want it.
This whole thing is a giant experiment for me, and if nothing else, I have learned a lot, and keep finding out how much more, I don’t know.
I would be lost without all the ideas and information I get from this site.
With that in mind, I am thankful for every response and suggestion I receive.

As mentioned before. No mater how good you think you are lining up your cross hairs you will do measurably better when shooting groups to change your POI/POA a 1/4 inch from each other.

I agree. This is one of the reasons I listen to this sites advice.
