Sako L61 for me. But I have not owned a lot of the ones listed

Browning A-Bolt

I like my Swiss K31
Its pretty smooth and fast to cycle

My Tikka Whitetail Hunter, Pre T-3

I wanna gain knowledge

I sold a Model 70 in .25-06 a while back because I got tired of diddling with the BOSS on it, but that particular rifle had the slickest bolt function I ever handled. I replaced it with a newer Model 70 Classic and I have no complaints...it just isn't as smooth as the older one was.

The old .30-40 Krag-Jorgensens are reputed to be the smoothest bolt-actions out there, but I never thought they were that special. But then again, I must admit I have handled only two of them.

For the money - winchester model 70!

I have:
700
70
03 custom sporterized
116
77
Vanguard
I have handled most every non custom major bolt gun.
I hate to say it but the howa 1500 is right up there with the best of them.

Panda and Bat are nice.

Tikka T3 for me with Browning A-Bolt close behind.

I hate to say it but my ruger old model tang safety 30-06 is the smoothest and tightest bolt action I have ever handled.
I have two pre 64 model 70's and have shot more than a few tikka's and sakos and frankly about any thing that I can think of except the blasers and it is still my favorite.

I find it interesting to see Mauser and Mauser type actions mentioned. They are solid as a rock and are probably sitting in the most expensive custom wood ever created. However, every one of them I have ever owned or handled just wouldn't hold a candle to newer designs like the others mentioned. A Remington 700 is smoother than any Mauser I have ever owned.

Nostalgia??

I think it really depends on the maker and the quality of the materials used in production. Another action that was mentioned that will suprise a lot of people is the Lee Enfield they are very smooth and built like a tank,too.

The colts I have held felt like wet ice on wet ice.
Hands down the slickest bolts I have ever tried.

MO

I noticed no one mentioned rem 788 , IMHO the roughest
bolt action out there.

MO

Yea but the most accurate.

Colt Sauer like a hydralic piston.

Ever made? I would bet none of us have ever handled it. Out of the ones I have had, a Stiller Viper was slightly smoother than a Tikka T3.

B.A.T. gets my vote

My Ruger Compact might give the 788 a run for its money. Its pretty rough. Still love it though.

Mauser/Krag Krag/Mauser

Of all the rifles I own, it would have to be an 1899 Krag Carbine that has the "smoothest" action.

a carl gustaf sporter that my brother had

1891 Argentine Mauser....hands down.

Its a completely different design than 98's. In fact, if you take a Argy 1891 bolt and lay it next to a Remington 700, they are very much alike. I sometimes think Remington got a few ideas from the 1891.

I worked a 770 that felt like plunging a toilet on an RV driving 70 mph on a rock road...that's about as smooth as a gulp of Steel Reserve 211
