I have a sidelock in a T/C renegade that is somewhat time consuming to clean. Can only comment about the inline that I bought recently, a T/C Omega. The cleaning is so much easier. Now some of that may be that I switched to 777 when I bought it. Anyway, the Omega is so much easier to clean that I shoot it more often.
=============================================
I own the Renegade & Omega! Both take the same amount of time to clean. Cleaning nipple holes, around hammers & power-flushing the bore with soapy water takes the same amount (or) less time than unscrewing breechplugs, cleaning them, anti-seizing them, inserting them, cleaning the Omega hammer/plunger area, cleaning residue from the trigger area and just below the hammer/plunger area.
Similar Omega-type designed rifles are easier than bolt/plunger spring actions, but I still think my trusty ol' percussion sidelocks are easiest... either with 777 powders or crappy ol' Goex.... which incidently -- I'll never buy again. Yuck-Yuck-Yuck... less power/energy & more stink/cleanup.
I'll have to admit though... I didn't mind the smell. I'll give real blackpowder another try before completely giving up on it... as soon as someone here tells me where I can buy some Swiss Blackpowder in the Detroit Michigan area. I'm going to Chicago in mid-August. If someone wants to draw me a map from our Great Western Hotel near Ohio St & Michigan St in downtown Chicago to the nearest Chicago Swiss blackpowder outlet, feel free to do so thru my private email.
Please enter "Swiss Blackpowder" in the topic of discussion -- otherwise I may accidently click the Spam button. Thanks In Advance!
P.S. I'm not interested in buying five tin cans of the Swiss online... thanks anyways in advance if you were giving some thought to entering a reply like that.
