Listen I do it. And will tell ya it only makes a difference to me if it helps fouling. Some guns it doesn't make any difference, some all the difference. You have already shot 60 rounds thru it, so the gun is pretty broken in already. I don't think its going to make a difference now. If the gun doesn't copper foul too bad, don't sweat it.

I think sako and Tikka say there is no reason to break thier's in. But I found out it helps some.
