Reloading is a science that not all may be inclined to partake in due to it not beingvery forgiving(accidents) in most cases as blackpowder loading might. Ive been doing it since I was17 and Im 39 now. One grain or even two can have devasting effects sometimes on pressure levels unlike blackpowder or substitues.This is why it is always recommended to reduce loads by 10% and work up looking for pressure signs. Sure the cartridges i spoke of are in contained cases but then explain why Savage is able to to produce a smokeless muzzleloader and just about everyone thinks its the best thing since sliced bread. The Encore can chamber anything the Savage cartridge rifles can and do.The Savagemuzzleloader is just a barrel attatched to a receiver with a breech plug in it.There is no locking lugs on the bolt unless they have changed them since the last time I looked at one. What would make it any stronger than a barrel made for smokeless powderfrom rifle grade steel for the Encore. I dont think the breech area of an Encore is going to give way on a blow out.If a company offers an alternative to the traditional blackpowder rifle and you buy it, you assume the responsibility of following their guidelines for their product and putting safety first. They have tested it and have to meet certain guidelines or they couldnt sell it. They arent going to put something out there that is going to mame or kill everyone who uses it.This type of rifle or barrel is not for every tom, dick, or harry out there that may not even have the mental capability of even using a blackpowder rifle with blackpowdermuch less one using smokeless. Alot of the companies dont manufacture them probably because of the uneducated people out there that would buy one and blow themselves up trying to hot rod their loads and using unreccomended powders like I have seen so many blackpowderor substitute users doing in posts. One example is people saying they are using fffg powder in cva rifles. Their manual does not recommend it, nor do they recommend loose charges over 100 grains, yet people do it then wonder what happens when something gives and they get hurt. Stupidity is usually the root of all loading accidents and is no excuse. Dont blame someone else, blame yourself. And by the way you can overload a pistol case and some rifle caseswith a double charge if you are not checking your cases before putting a bullet in them.
