Took a ride to Stoneham to purchase some Serbian .308 for my Rem 700p. It was cheap and thought I'd stock up. The brass is obviously the same size but the bullet itself is a bit longer than your ordinary store bought brand. I took a Serbian, Winchester and an American Eagle round and with safety on, chambered a round to feel the difference. The AE and Win slid in perfectly with the bolt but the Serbian needed a bit more of a push to be chambered. Is it the length of the bullet itself that's causing this? and could this lead to any problems?. If you havent a clue what I'm talking about, I do apologise and feel free to call me at 978-290-7950. thanks, Matt
