gunner Posted December 5, 2014 Report Share Posted December 5, 2014 Is it wood? , the colder damper weather will move timber, besides a sheet of paper measures 5ish thou , you need 2mm really for peace of mind Link to comment Share on other sites More sharing options...

spanner Posted December 6, 2014 Report Share Posted December 6, 2014 If it shot ok off bags or wing mirror but crap off a bipod then the float is the issue. A friend of mine had the exact same rifle and had just that problem. Link to comment Share on other sites More sharing options...

abolter Posted December 6, 2014 Report Share Posted December 6, 2014 unless you home load red hot it shouldnt be. Do you always take the mod off? my 22/250 was fried at about 2500 shots but not worse than 2" groups Link to comment Share on other sites More sharing options...

Do you always take the mod off? my 22/250 was fried at about 2500 shots but not worse than 2" groups Using 32grns of Tac so not that hot and yes I take the mod off every time.atbEd Link to comment Share on other sites More sharing options...
Georgek80 Posted December 7, 2014 Report Share Posted December 7, 2014 I had a remmington 22-250 a. Few year ago I home loaded with varget just under max load I got less than 2000 rounds through barrel before it started spraying bullets Link to comment Share on other sites More sharing options...
visiter1 Posted December 7, 2014 Report Share Posted December 7, 2014 have you tries a deep clean on the bore? Link to comment Share on other sites More sharing options...
JB1 Posted December 7, 2014 Report Share Posted December 7, 2014 All nuts and bolts tight you say, barrel now fully floating, group's not good with or without mod, same loads that previously shot well. If all is you say then, has the crown been damaged if not then I would change the scope then check groups. To go off that quickly points to something loose Link to comment Share on other sites More sharing options...
Borisserge Posted December 7, 2014 Report Share Posted December 7, 2014 Give the rifle a good check over, give the barrel a good scrub and try factory ammo through it without the moderator. Basically remove all variables, then move forward from there step by step adding your kit again. Link to comment Share on other sites More sharing options...

Akeld Posted December 8, 2014 Report Share Posted December 8, 2014 Are the rounds the same batch that were shooting well or a new batch? Might be worth checking weights and lengths Link to comment Share on other sites More sharing options...
gbal Posted December 8, 2014 Report Share Posted December 8, 2014 Visiter and Borisserge have both advised a thorough clean-barrels do shoot out of course-but usually there is some decline,not an overnight dramatic worsening....but that can occur with copper build up-do you use copper remover? Try a very thorough bore scrub out,and copper removal-you get immediate feedback as the patches will come out blue/green depending on the copper remover used.....you might need quite a lot of wet patches through,and leave some for a while (hour at least).You haven't said anything about cleaning regime...but it does sound like a within barrel issue-worn or dirty/coppered...given all the other checks which have not solved it,so let's get the barrel clean,at least. gbal Link to comment Share on other sites More sharing options...
dully1963 Posted December 9, 2014 Report Share Posted December 9, 2014 Have a look for crown damage , all the best dully1963 Link to comment Share on other sites More sharing options...
Dragonlr Posted December 9, 2014 Author Report Share Posted December 9, 2014 Had the gun looked at by local custom gunmaker/gunsmith he said barrel is clean of both copper and carbon,crown is undamaged,all relevant stock bolts and scope fixings are all tight only thing he could see was rust & crud on the Mod thread on the end of barrel all cleaned off now ready to try not had chance yet if still the same with no mod must be the scope will put another on to confirm and let you all know the outcome.atb Ed Link to comment Share on other sites More sharing options...
Borisserge Posted December 9, 2014 Report Share Posted December 9, 2014 Hi Ed, good to hear the smith gave your rifle a clean bill of health. When you do your testing, if possible, use factory ammo. It removes one last variable out of the whole conundrum. Lastly, shoot with and without the moderator. Link to comment Share on other sites More sharing options...
gunner Posted December 9, 2014 Report Share Posted December 9, 2014 What scope is it out of interest ? Oh and modd? Link to comment Share on other sites More sharing options...
JB1 Posted December 9, 2014 Report Share Posted December 9, 2014 I think it was quoted the scope is a pm2. My 1st thought after the op's comments was scope, it may or may not be, but it's got to be the easiest and quickest check.I will always be scope swap in these circumstances. Just because you spend 2k on scopes does not make them infallible. Link to comment Share on other sites More sharing options...
