Like Andrew said above, I use a straw thru my .22 RAW's barrels to bypass the baffles using a Patchworm pull thur or the end catches in the baffles. Just find the correct size straw!
The straw idea worked. Thanks everyone.So I'm just using a wet patch pulled through with JL Crown Saver. Is there any need to scrub the bore with a brush like with a powder burner?
