[QUOTE="Tikkamike, post: 382865, member: 22242"] Winmag, Yes there can be a negative effect from tumbling. To me it kind of falls into the "to neck turn or not to neck turn" kind of argument. According to varmint al's website he refuses to tumble because it puts tiny knicks or dents in the case mouth thus creating an uneven case mouth which he finds to be too detromental to accuracy for his liking. The bullet needs to leave the case evenly and simultaniously on all sides or it could theoreticaly start the bullet in the lands less than perfectly square. However in my opinion if you were that worried about it you could keep your cases trimmed to sammi minimum which if you neck size only you would be pretty much be just polishing up the mouth of your cases each time but they would be square. I have never expiramented with his theory but it makes sence, maybe only applicable to bench resters though... it may be worth investigating. I do not tumble very often and after reading that I decided I would only tumble if I knew I was going to trim. Thats my thoughts anyway [/QUOTE]
