Accuracy: Chassis rifles vs Manners Mini Chassis

[A5scott]

I have MPA and XLR built chassis rifles and they shoot very well. I'd say 1/3rd MOA with hand loads is no problem. I also have rifles built on Manners Stocks with the mini chassis built in, and they shoot 1/3rd MOA with hand loaded ammo as well.

I feel like both platforms are equally accurate, but I also feel like if I'm going Manners, I mostly want the action bed in the stock without a mini chassis. I say this at the same time I have a T2A GAP with mini chassis on order lol. I wanted the ability to share the stock among different barreled actions if needed.

Anyone with both types see any accuracy differences?

There is no need to bed a Manners Mini Chassis. I have had a bedded Manners, a bedded mini chassis and now all I use is standard mini chassis stocks as like you I like the ability to move it to another barreled action if need be. All the above were accurate and the bedded mini chassis was no more accurate than the barreled action dropped into a mini chassis. That bedded mini chassis was done back around 2012 and I'd never bed another.

Thank you for the replies...

I must have been confusing.

When I said this in the original post: "I also feel like if I'm going Manners, I mostly want the action bed in the stock."

I meant bedding the non-mini chassis version of Manners stocks.

I don't bed my MPA or XLR chassis, and I've only owned one Manners Mini chassis rifle that was skim bed, but I bought it that way. It was an Accurate Ordinance build that shot excellent.

My newer Manners mini chassis rifles have that little square on the rear tang screw hole area to take care of the banana.

I'll distill my question to this:

Does anyone notice an accuracy difference between Manners Mini chassis vs pure chassis rifles such as but not limited to XLR and MPA.

There is no accuracy difference between stocks or chassis, all things being equal. The difference is shooter fitment and how your body interfaces with the gun. This is why chassis are so much more popular, as they can be made to fit just about any body shape and shooting style. Traditional stocks like Manners or Foundations are much more limiting and unless you have the body that matches the stock, you are adapting to it instead of other other way around.

I'm of the mind that there is no discernible accuracy difference, but I was curious about what others thought.
Chassis do have the benefit of modularity, and I shoot both chassis and stocks equally well. I do prefer the angled butt of a nice stock like a T2A that can ride a wedge bag.

Yes I'll always keep a chassis and a Manners mini chassis in the lineup for Rem 700 clone compatibility.

My barreled action in a mcmillan a3-5 seems to shoot fine without bedding. I'm considering swapping to an mdt chassis eventually just for the amount of adjustment. Never really used a chassis so I need to get behind some first.

You do know that data is from like 2019. A whopping 5 years ago.

Today MDT and MPA dominate the market. Probably 60-70% of shooters are running one of those 2.

How old is that? I didn’t even see one JAE at a match last year and couldn’t find an ACC Premier or Elite farther than 20ft away.

probably from 2018 or so.
