I know the two are bolt 455 and semi auto 512. I'm looking to see if there is anyone who has experience with either or both. I'm finally flush with cash and looking to invest... Or just enough to afford one, potaTOE/poTAtoe.

 

I've been having a tough time deciding of bolt or semi. I know that bolt with help with discipline and should be more accurate but the ease of a semi is appealing, plus home defense in a pinch. I may be be trying to balance too many things with that issue. To stay on track, opinions or first hand accounts of either rifle is appreciated. Or just plain old advice. Thanks guys.

As always correct answer is to get both. Personally I got 455 and m&p 15-22 to cover interest in bolt and semi-auto.

455 is a very nice rifle. I put a nikon prostaff 3-9 rimfire on mine. Very accurate. Was shooting 45 acp casings at 50 yds consistantly. I've had zero issues in ~3 years. And it sure is one looker.

I've had both 455 and 512.

still have the 455 which is a pleasure to shoot.

 

Eventually sold the 512 and bought a 10/22 to fiddle with.

 

512 had wonderful fit and finish, shot well, but has an odd manner of disassembly and reassembly.

Get the 455 combo, 22LR and 17 HMR.  That's a nice arrangement.  Squirrels on one side, PDogs and similar critters on the other.
