Dougy Posted April 22, 2007 Report Share Posted April 22, 2007 I have a Sako 75 heavy barrel and have put about 150 through. It groups ok with the right load (home loads) with just 2 shots then the 3rd always goes low left. Has any one any idea what could be the problem. Shooter error can be ruled out so can shooting 3 in quick succession all the loads are accurate. It has been mentioned that the scope may be faulty then someone else said that if that was the case then why is it that 2 group well then the third moves then next group is not too bad. If it is the scope then it wouldn’t go back to being the same POI The advice I have been given is from 2 experienced rifle owners one of which is a FLO with a good knowledge of fire arms. Looking forward to hearing from any one with an experience with CF. thanks Dougy Quote Link to comment Share on other sites More sharing options...
steve b Posted April 22, 2007 Report Share Posted April 22, 2007 If you are shooting in quick succession maybe it is the barrel heating up, try allowing it to cool between shots and see if this helps Quote Link to comment Share on other sites More sharing options...

Peter_HMR Posted April 22, 2007 Report Share Posted April 22, 2007 Clean fouled barrel? If its been recrowned did it do it before? Quote Link to comment Share on other sites More sharing options...
Dougy Posted April 22, 2007 Author Report Share Posted April 22, 2007 clean barrel had it skrew cut straight from new so didnt try it. But it was mentioned by a FLO chap in the local that there could be a very small imperfection in the crown that would get worse as it got warmer, and as its always low left it is a possibility. will need to check having one go in the morning taking 10 minutes between each shot see what happens. then back to the RFD Quote Link to comment Share on other sites More sharing options...
Peter_HMR Posted April 22, 2007 Report Share Posted April 22, 2007 Some barrels shoot better when they're dirty. As a last resort i would chop of an inch and get it recrowned. Quote Link to comment Share on other sites More sharing options...

Dead-Eyed Duck Posted April 22, 2007 Report Share Posted April 22, 2007 Process of elimination. Borrow a decent scope and try that. Zero without the mod on, to eliminate that. I know that it is a heavy barrel, but take a couple of minutes between each shot. Mark each group carefully so that you can see if it is anything to do with barrel warming. It's not clear from your post, but you mention that you have put 150 shots through it - is it a new gun? If the gun is 2nd hand, and it is still poorly grouping after all of your efforts, then get it re-crowned. Don Quote Link to comment Share on other sites More sharing options...
Dunkield Posted April 22, 2007 Report Share Posted April 22, 2007 I would consider that Sako have done it ok. Sako pillar bedded and floated the barrel on your gun? Quote Link to comment Share on other sites More sharing options...
v-max Posted April 22, 2007 Report Share Posted April 22, 2007 Hello have had this problem with mount's/base block's being loose.I know it may sound a bit effort but strip it all down & locktite or clear nail-varnish the screw's & try again at the target.This happened to with a 25cal & it was alway's 3rd shot & wheather someone else or me it shot the same 3 shot group & it was loose mount that was our problem.

Dougy Posted April 22, 2007 Author Report Share Posted April 22, 2007 maybe it was silly of me but there again i have put home loads through it also, which again voids the waranty anyway. as for the bedding bit. well it looks to me that there is some funny looking stuff at the front of the recieving block. Dont know as i'm new to all this stuff. just come from shooting air rifles its a bit different Quote Link to comment Share on other sites More sharing options...

Dont know as i'm new to all this stuff. just come from shooting air rifles its a bit different Well I didn't think there was such a thing as a Sako factory bedded rifle. If you are new to this have you had someone else shoot it for you? Don't be insulted by that, 22-250 are a bit barky, so it may be that a more experienced shoter can tighten those groups up a bit, may be worth a try... If it helps, I have a whole drawer full of '2 shots together, 1 shot pulled' targets at home Quote Link to comment Share on other sites More sharing options...
lazza Posted April 23, 2007 Report Share Posted April 23, 2007 I think stuartp has given good advice. I had a few problems with the mod on my 22-250, which I managed to sort out. however I did have a ball ache with my 17. I ended up letting someone else test it to see if they had the same problem as I was having. The good news was that they did, the bad news was that I needed a new scope.

deadeye ive Posted April 23, 2007 Report Share Posted April 23, 2007 Well I didn't think there was such a thing as a Sako factory bedded rifle. Where as my re-coil lug on my Tikka is a seperate item and fits into the stock with ease the one on the Sako is fixed to the action and has been resin bedded into the laminate stock .This makes it very difficult to seperate the stock from the action BTW. I think we can all agree understanding the variations that fullbore throw up will put even the most experienced shooters in the funny farm if they let it get to them.
