I use a Tipton .22 cal. (spear tipped) brass jag #356987 and buy several at a time. I prefer to bevel the lead edge slightly ... as I find it allows the patch easier starting entry into the chamber. Reducing the jag diameter to allow for just a snug fitting patch, as mentioned by the posters above, is very good advice. An extremely tight fitting patch and jag combination, which causes the cleaning rod to bow, may lead to bore damage with extended use, even when using a well aligned bore guide. John
