Chassis vs. Stock

[vintagearms]

Depends on the shooting discipline.

Some folks shoot conventional prone (NRA highpower rifle) while others do F-class, PRS, or Benchrest. Each discipline has its own tools for the game.

Last year Manners was the preferred stock for PRS with MPA holding second place, Benchrest shooters mostly use stocks over chassis, and I believe F-Class as well.

So out of the box, a fibreglass stock compared to a chassis, a chassis should be more accurate/repeatable based on stability and how rigid it is.

Should be but in the real world they are not. Most chassis have too much flex. And I think your chassis has a nice look to it.

Actually it doesn't depend on the shooting discipline.
You can measure any paper target there is and a chassis gun never outshoots a conventional stock for smallest group. At your next F-Class match measure the groups.

Same holds true in 22 rimfire.


As for "accuracy" everyone has their own idea of what that means based on their discipline that they shoot. I know it's hard to throw examples out there on records chassis rifles hold compared to other stock options but the first thing that pops into my mind is that currently, the longest recorded kill in action is from a chassis rifle shot by a Canadian at 3,540m (3,871yards).

That would only be accuracy if he made 5 shots and 5 kills and in the same situation another sniper of equal talent couldn't do it because the stock was the limiting factor.
In your example wasn't the Canadian sniper using a McMillan Tac-50 stock and not a chassis? I ask because McMillan offers it as a flat top semi inletted or fully inletted.

What would you consider the most popular action footprint in say PRS, NRL and F class competition?

I would say some form of the Remington 700 for sure. And that is where you run into variances as mentioned earlier with that other style of bedding. Every manufacturer of a 700 'clone' is that it is the same 'footprint' which means action screws and usually recoil lug. Then you get some actions with different shapes where they go a little thicker on the action size or they change the shape to a more angular top design instead of rounded.

All these factors come into play when using a standard stock which with their standard inletting would require bedding in order to make them fit, while in a good V-Block they will be secure and supported.

I'm saying out of the box, I know there is a lot of work that goes into creating a competition ready stock and along with the bedding, a lot of stiffening.

Then that brings up a question where you get into the higher end of competition shooting where the lines blur.
I know a lot of guys who shoot bench rest have those mostly hands-off contraptions which don't don't even have a buttstock which are free recoiling things that aren't conventional stocks by any means, but could best be described as a chassis of some sort.
Then I also see pictures of new attachment mechanisms which are a barrel block clamped at the chamber giving you more stability and strength where the most vibration occurs and the rest of the barrel and the action are free floated. These are usually in some form of conventional'ish wood / fiberglass stock but with that big block is basically an aluminium chassis that has been inserted into a stock.

The Canadian sniper was using a TAC50 but it wasn't in a McMillan stock it was in a Cadex chassis.
