I always clean the barrels of all my rifles after about 300 shots, sometimes sooner, I then need around 10 pellets put through to settle the gun as you say Neil. Some people think I overdo the cleaning, but I find it works for me, in fact I definitely get better groupings when the barrel is clean.

I also clean and lube all my pellets that I am using for zeroing or hunting/competitions. I could maybe not do this now as the quality of the best pellets is very good, but I started doing this process years ago and it works for me.
