Bolt action rifles for me, followed by lever action rifles. I don't know why but there is just something fun about running manually operated firearms. I also really enjoy precision shooting and it's hard to beat bolt guns when it comes to accuracy. I also enjoy shooting Magnum calibers so that is what most of my guns are chambered in.
I don't know why but I don't find semi-auto rifles all that exciting to shoot. Mine mostly sit in the safe and collect dust.
Funny enough though I love semi-auto shotguns. Over/Unders are oddly fun to shoot, too. I plan on getting one eventually for trap/skeet/sporting clays. I have no interest at all in pump shotguns. Had a few and didn't care for any of them aside from my Browning BPS.
Don't care to shoot handguns at all. I'm also admittedly not that great with handguns and am super hit and miss with them. There's a few I shoot really good with like my CZ Shadow 2, USP Expert, Sig P220 series, Glocks, and revolvers... everything else I have tried beside those, though, like the Beretta 92, S&W M&P, HK P30, FN FNX, etc., I have shot very mediocre.
