Pretty much same here, just less time frame.
I had a 783 and it shot like a house-a-fire to say the least. I simply do not like/trust tubular magazines! I had a 14" Contender too, great accuracy. Then I bought a then new Ruger 77/22M in Varmint 22Magnum. Shot 2+" 100 yard groups.... I bedded the barrel and cleaned up the in-letting of the action. No real improvement. I changed out the trigger and bought a new Leupold 4x12 AO scope and different ammo. It would shoot occasional 1" groups with FMJ ammo. This is it did not matter if it was CCI, Winchester or RWS!! I pulled off the barrel and sent it out to be cryogenic frozen to stabilize it. All told I had some $$ wrapped up in this gun... STILL coupld not get it to consistantly group at the majic 1" mark... A customer saw it, fell in love and paid me everything I had into the gun. (I kept the scope) so I sold it... Then Fed came out with the 30G Premium and Win brought out the 34G varmint ammo. He brought in groups under 1" with BOTH of them!!! GRRR It was a pretty stainless Lam wood stocked gun... Somewhere along the way I sold off that 783 too...
I bought a new H&R 22M it shot OK but not as good as that Marlin. then the 17HMR came out, I bought one of them and shot under 1" out opf the box... out the door went the 22M barerel!!
I too have shot a couple coyotes with it, many chucks and a couple squirrels. Devistatingly accurate and effective bullet preformance.
My 17M2 is far and above the most accurate rimfire I have ever fired! I have shot ALLOT and some VERY hi dollar firearms too!!! Coopers, Brownings, Anshutz, Kimbers... BIG dollar companys offering beautiful finely crafted firearms and my 17M2 H&R @ $150 out shoots ALL OF THEM!!
I do have two wonderfully accurate 22LRs. A CZ long barrel with a 6x18 AO scope and a Marlin 780 Squirrel I customized with trigger, beddings and nice Walnut stock. Both shoot great, but I want a bit more power...
I just "want" another bolt 22M.... For allot of us, It's never about "need" anymore..

MAN I LOVE THIS STUFF!!!
