Break In Time for L7 Bolt ?
I just installed an L7 bolt in my Vibe. I was hoping to see an efficiency gain, but the chrono was reading about the same, perhaps a little slower with the L7 bolt compared to stock.
My fps spread for a 10 shot string went to crap with the L7 bolt too. With the stock bolt I got +/- 8 fps. With the L7 bolt there was one super slow shot that brought my spread up to +/- 20 fps!
I also had a double-feed, which has never happened with the stock bolt.
I'm going to clean up the L7 and make sure there isn't too much grease on it to make sure I don't get any bolt stick, and try different detents and larger paint to try to address the double-feed issue.
How long should I expect it to take for the L7 bolt to be properly broken in? Half a case, two cases?
