I started with a Rem700 Classic 6,5x55 topped with a Zeiss 6x42, later 8x56. Worked very well, was never unable to shoot a deer with it. Used 120gr NBT
I tried building my PERFECT DEER RIFLE around that time. Spoonfed by gunwriters, it was as close as I could get on the cheap, it was Sako Vixen 6mm-223 shooting 85gr Sierras. Shot maybe 30-50 deer, mostly bucks. Found it lacking, a lot of deer ran far.
Returned to a 2nd hand Sako Finnbear 6,5x55 in a McMillan stock as I wanted something weatherproof. Used 140gr Amax and grew proficient as a hunter with that rifle. Used a Zeiss 8x56 scope, later a Schmidt Bender PMII 4-16×50.
Used a Sako Forester 243. The 87gr Vmax dropped the deer really well. S&B PMII 4-16×50 was moved over.
Bought a Blaser R93 270 when it was time to rebarrel the Sako. Changed calibre to 6.5x284. Sure, it worked too. Shot 123 and 140 Amax. Used a Zeiss 2.5-10×50 scope but switched to my S&B PMII 4-16×50.
Upgraded the R93 to R8 and tried a 300 NM with 225gr Hornady ELD. Way too powerful. Got a 6 XC barrel and have shot a few deer with that (30?) using 90gr NBT and 105gr Amax. Works very well. Using a Minox ZP5 5-25×56.
Tried building the PERFECT DEER RIFLE again a few years back. With a few hundred deer under my belt, it was shaped by my own ideas. Sako action with a synth stock mated to a Lilja barrel and topped it with a 5-25x56 scope. Chambered for 6,5 Grendel shooting 123gr Amax, it worked too and it cost a lot more than my first rifles.
All in all, the only thing that has happened is that my pricetag and weight has increased. I always invested in top optics and wouldn't change that, but I have really wasted a lot of money on rifles. When all is summed up, I could probably have done a really fancy hunting trip for that. Looking into my closet, it is depressing to see how much $$$ I have turned into gear I don't use.
Here is a film with my PERFECT deer rifle which I threw a lot of money on and ended up not keeping
