Ballistic Products promotes mostly their products. That's why I don't usually buy from them. I feel they're over priced and all the reloading data I have doesn't include their products. Anyways, you may want to check the base wad in a Fed hull - it could be paper. Those have been known to come loose and lodge in the barrel. That's why I buy the Rem 10ga hulls [ from Precision Reloading ]. As far as changing components, most guys don't, especially if your load is near max pressures. Now if you're loading at low pressures, like I do, there's a little lee way. Win, Noble Sport, Cheddites, CCI, Rem primers are all medium primers where as Fed and CCI M's are hot primers. If your data calls for a medium primer and all you have is a hot one, then going down a full grain in charge is ok in IMHO. I have many reloading guides from the powder companies and any load is shown with about a 4gr spread depending on what velocity you want. The faster the load, the more pressure. So if you only have a load with high velocity you can always go down a couple of grains. Try em and look down the barrel to see how dirty it is. Too dirty and you're not burning all the powder. Also, you can always use fiber wads from
www.circlefly.com - with a fiber wad pressure won't be higher - if anything lower. In rifle reloading, a tenth of a grain or two difference in powder makes a big difference where as in shotgun reloading a three tenth spread is a lot of times normal. Just about all powders can be loaded with a four grain spread [ not tenths ]. You have a bigger safety factor. Good luck - Paul
