I'm an unabashed Swarm Maxxim fan. I've had two, both in .22 caliber. At fifteen yards, I do consider the accuracy better than expected, and equal to, maybe a little better, than the TX200 I just bought...although the TX isn't thoroughly broken in yet, and I expect that to change. I agree that the scope is absolute garbage, so I mounted a Hammers 3-9X32 AO scope on it, much better.
The reason I have had two is because a neighbor broke the feeding mechanism one night, and I shoot so often that I didn't want to be without the rifle, so I trotted down to Big 5 right then and bought another. I was concerned that the second one wouldn't be as accurate as the first, but after a cleaning of the barrel...the second one wasn't as filthy as the first...and moving the Hammers scope over to it, it was shooting every bit as accurately as the first one.
I got the replacement feeder from Gamo under warranty, put it on the first Swarm, bought another Hammers scope, and sold it all to another neighbor for the price that I had paid for it all, and bought the TX! I pull out the Swarm almost every shooting session, since it's just so much fun to shoot.
I've read all the comments and reviews regarding how inaccurate the rifle is. Admittedly, my experience has been with only two rifles, but both were purchased off the shelf, nothing fancy about them, and they are both just about tackdrivers. So, for those folks who complain about inaccuracy, I've just gotta wonder that it's the human element that's the issue here... not the rifle.
Before I handed the first Swarm over to my neighbor, I sighted in the new scope I bought for it, got it printing great groups at fifteen yards, and let him have at. His targets look like a .410 shotgun! I've instructed him in what works for me in that rifle, I've observed him, but I can't look down that scope with him. He looks to be doing everything right...but he can't shoot up to the potential of the gun.
Long story short...I'm a fan of the Swarm Maxxim. Another neighbor bought one in .177, just loves it, but he also can't shoot it as well as mine prints. I've shot it, and I know that it's also accurate. It's just the human element at issue here, and part of that element is the fun you have with the rifle, and all three of us are just having a ball! A great and fun rifle for the price!
