I have been using reloads in my 243 wssm for over a year now. I usually shoot 85gr sierra but I got my buddy to load me up some 55gr sierras( 44.5grs of 4895) this time. I went shooting the following day, I had one neck to split( which I figured it was due to being a hot load) But my concern is when I was chambering a round, some of the ammo made the bolt hard to turn . The brass was only on its second reload, so I dont know what could have caused it. Any ideas would be helpful.
