I have a fairly new rem 700 sps 204 ruger and it has feed issue. I load 6 rounds in the internal mag and all the rounds bind about 3/4 way of the bolt closing. If I force it will put small dents on the sides of all the rounds, about 1/4" down from the neck. I have to go slow let it bind up and then pull back and try it again until it slides in. I have put about 200 rounds in it. I recently put a muzzle brake on it and now it is worse. It used to do it ever so often but now its every round. Any help would be great. Thanks.
