Hi everyone, I have a membership pending with Lowell Sportsmans club but I recently found out that they do not allow jacketed rounds in their indoor range. Can someone tell me what the diff is between jacketed and unjacketed rounds? Do the unjacketed bullets foul up your guns over time? If this is the case I am gonna pull my application out of Lowell and look into joining Westford. Please excuse my lack of knowledge, I am new to all of this.
