Just isolated a little snag with some brass, I reload amongst others, the 7mm WSM, & was a little perturbed to have cases remaining in the chamber when they should be flying out the side, I had loaded some necked down 300 winmag, as the 7mm WSM was not on the shelf when I visited the dealers, some were from Winchester and some from Remington Peters, the Remmy's must have a minutely smaller base circumference, as every single one of them stays behind on drawing back the bolt on firing, this then requires the cleaning rod to be inserted to poke out the cases.
