Flat Bottomed Actions

I my opinion,its the other way around. Round actions are used by all BR manufacturers and Remington because they are easier to bed.
 
Flat bottomed actions should give more secure bedding. More surface, and not able to "turn" ihn the bedding.

There are easily as many flat bottomed actions in BR as round...,Viper/Panda are flat)

Even my 3 lug BAT has a flat on the bottom to help prevent torquing, and they are no harder to bed than any other style would be. There is also a small flat that runs the complete length of the receiver. My BAT SV has only the flat in the middle of the action.
Even my XP's have a flat that serves as a type of mortise to prevent rolling as our #1 shooter mentioned. They are no harder to bed either .......
 
Back in the day when wood stocks were the norm, in LR highpower the Belted mags ruled. A rd bottom action such as a Rem 700 would torque as the bullet went down the tube & break the stock or the glass bedding. For this reason the Model 70 was the favorite. With todays synthetic stocks & better bedding materials it isn't a concern. M9

There is a lot of Engineering and Physics being thrown around here. Round bottom actions versus flat bottom actions. If you have enough actions you have both. I don't buy the flat bottom comment that torque is absorbed better with a flat bottom action. If anything a round bottom allows and even distribution as the action and the stock become one when bedded. Loose action screws might allow the stock to absorb torque better with a flat bottom action but how many of us shoot with a loose screw or 2, no comment on that one.
I also don't buy the better to bed comment just the opposite. A glue-in if done well is the same with either action. A Pillar bed is same with both. A glue & screw which I like is the same with both. Bedding a Hall action compared to a Winchester makes you a believer in round bottom actions sooner than not. But I would not avoid an action based on flat or round. Action holds the barrel and the trigger and a place for the scope to camp out on, so be it.

I don't think it takes a physics genius to realize that a rd action can turn in the stock easier than a flat one. As I said with today's improved materials its not an issue. That's what rd things do is turn. As the inventor of the wheel discovered many moons ago. That's why a Mauser is flat. More modern rd actions such as the Remington 722 became the darling of the benchrest guys, mainly because a triple deuce with a slow twist doesn't torque the action enough too cause problems. OTOH the Model 70 became the darling of 1000 yd Highpower, because a 300 H&H does torque the action enough too cause problems in a wood stock, particularly with a quick twist for long boat-tails.

SP - it is simple physics...yet you continue to argue...

More surface area = stronger/stiffer bedding

Flat = can't torque/twist
Round = can torque/twist

We're talking torque, not recoil force...

Though only theoretical advantages, likely not quantifiable in the real world, they are still facts.

Just like a short and or single-shot action is stiffer and more accurate than a long and/or mag-fed action...
