My brother is a fabricator, he has already ordered 2 or 3 different slug molds. I think you are talking about hollow skirt slugs? If not I’ll ask my brother what bootlets are. Scope is exactly what you said. I have read the little book that came with it. I suppose you meant you hoped it would stayed zeroed once I set it. It has a warranty, so I will test it throughly. I have a Burris Fast Fire 4 I will replace it with if it turns out to be junk.
If you meant will it set at a certain distance zero, it does that as well. Locks and unlocks on that setting , easy to adjust for holdover and return to original zero. I just have always bought parallax free scopes , don’t figure I’ll ever need 24x magnification for anything unless I use it to sky watch or something.
The rifle is supposed to be accurate , more so than most big bore air rifles typically are, there are several YouTube videos of people demonstrating it. Even at 50 cal people are getting 930 to 940 fps and that translates to over 400 ft lbs at the muzzle. 50 cent piece sized groups at 75 yards, all holes from slugs touching. It has a threaded barrel to accept a moderator without any adapters. I elected to put a muzzle brake on mine as moderators are outrageous in price and I just think the brake looks cool on it. The Megalodon is AEA’s latest release that’s not a handgun type of airgun. I researched a good while before I bought anything. It seems AEA used lessons learned from previous rifles when designing the Megalodon. My only dislike at this time is the magazines(it comes with 2) are just cheap plastic or polymer, I doubt they hold up in my world. I guess many of the semi auto air rifles will start jamming for several different reasons. I guess they have the pump action working pretty good. All and all, it seems like a well put together rifle, time will tell how well it holds up. It has tanks that will stand up to 4500 psi and shoots unregulated full power. 2 mags or 16 consistent shots if using both tanks, rear tank can be removed and replaced with a folding stock. With the single front tank it gets about 8 consistent shots. The folding stock makes it really compact , especially the 15 inch barrel version. I have the 22 inch barrel. I have slugs on the way the guy at the air rifle shop sent me because I wasn’t suppose to get a 50 cal, I ordered 457 , someone got confused and sent the 50, so when I decided not to return it and get the 457 , the guy sent me 50 dollars worth of slugs from Mr Hollowpoint. I really originally had 357 in mind, but those have not been produced yet, I think they are still I month away or longer.
