Thanks for the replies folks, much appreciated.
Lawrence - I am running Redding Delux die set.
- yes I checked the case length, and all are at recommended trim length or shorter (1.902 +-.0.003). Two that chambered were 1.9055 & 1.9045 and these were the longest. One that - didn't - was 1.895. So I don't not think length is the issue, and perhaps suggests that the chamber is OK, and not particularly 'tight' as suggested. Though this could still be the case on another dimension.
I have FL resized quite a few other sets of cases (Remmington, Win Super X, Federal) for the same reason - fire formed in the old rifle, and needed to resize for the T3 x, and overall these other cases chambered well, and perhaps only 2 or 3 needed a second run through the die, then they were fine. By fine I mean no struggle or pressure required to close the bolt. All these with similar case length specs to the current batch of recalcitrants.
I will try shimming out the case in the shell holder and see if that makes any difference.
SCJ49 - yes, I have thought of that, might still happen just for a fresh start. What brand cases then?
Wm.Traynor - yes, will give that a try too. Thanks.
Keep the ideas coming. Oh, and what is a 'small base die'?
Kind regards,
Paul
