This one guy at Kames said that if you use a 209 primer then it might effect your accuracy because it has too much of a blast. So..when the trigger is pulled, (if your using 777 pellets) the blast goes throught the holes in the gunpowder and hits the rear of the bullet - displacing it - before the gunpowderevenignites, effecting your accuracy. He told me to use a 410 primer instead (for better accuracy). Is this true????
Yep, can be true. Just cause one guy had one experience on one gun, doesn't mean much.
But they are designing the hole to control this I have noticed. I know the revolution changed its breach from when it came out due to this. so for some guns designed to keep the spark down, you might be hurting yourself.
I have only experienced crud rings on T/C's, never my knight. The believe which seems pretty valid is that in some guns, the initial impact of the 209 pushes the load up before igniting causing an air gap.
