I've now solved the problem, if ever there was one (probably listening to someone (no lets name him.a mr andy allwood)who thinks he can reload, and telling me I've got an overtight chamber and there is nothing that I can do about it, and should have bought a decent gun not a tikka!). The problem was letting him set the full length die up in the first place. yes he didn't give it the extra 1/4to1/2 turn as Paul'o on here said to do. And I didn't question it because I'm thinking this man knows his stuff, what he says goes. ( don't I feel like a idiot!!) so I got in earlier from work and thought I would have a play. I reset the fld up from scratch with the extra turn and done a couple of cases, chambered them and hey presto the bolt went down with ease, stunned f,ing stunned so thought I would do a few more and all chambered lovely. Now I originally done this with with neck sizeing die and it didn't matter if I turnd it that extra little bit or a whole turn or many turns, the cases just wouldn't chamber after . Mr allwood was right that I needed a fld but totally bulls'd up on setting it up right! I just want to say thank you to everyone for helping I am most grateful to you all thanks again.
