Bedding a chassis gun

[diver160651]

Yeah, I think his comment was slightly out towards left field.

^^^ this

BTW of the 4 images I saw, the weight system, the Castle Cut and not shown, the vertical grip with grip interchangeability, are fairly hard to duplicate on a stock if that is what you are after.

Some places like RO, dictate mag changes on the clock, I just wrote the COF for our match and we have stations were the mag must be inserted on the clock. Other places like a roof top also can take advantage of the castle cut.

That said, I run both stocks and chasis.. Plenty of guys and ladies (Regina) winning with and without a castle cut.

But at the end of the day it is about options at a price point.

A typical high end bedded Manners or McMillian, with top notch bottom medal and Arca rail is going to 1/3 more 1K vrs about $1500

Randall, If a full bedding is to be applied how much bedding front of the recoil lug for a varmint barrel chambered in a 30 caliber magnum? Is it better to omit bedding supporting the barrel just in front of the lug for a full free float or have at least an inch to support long barrels 24-30”?

[ar15barrels]

I don't like bedding forward of the lug because it has to be re-done at each rebarrel.
For a hunting gun that will never get rebarrelled, you can bed 2" forward.

First off, I don't need the index card attached to my rifle for DOPE, there are other options for that. My McMillan has adjustable cheek piece, and I don't need adjustable length of pull. And yes, I find chassis rifles unnecessarily heavy. It has nothing to do with what I can and cannot carry, I just don't see the need to lug around a hunk of aluminum for no reason other than to look "tactical."

Yes, your comment about hitting the gym seemed to be directed towards me in a negative, and frankly, my feelings were hurt.

Also a cutaway magwell for faster reloading.

I'll need to go home and see which bottom metal I have on my short action, but it has a similar cut out on my long action
. Besides, even with my .223 trainer, the mags all stick out enough that I have never needed more to reload.

He comments about how heavy chassis stocks are. How much heavier are they compared to McMillan or Manners stocks? Those two manufacturers certainly aren't lightweight either, especially if you have adjustable buttstocks and cheek risers. Unless he's talking about plain-jane B&C or H-S stocks which can be lighter.

My McMillan was about 3.5 pounds with adjustable cheek piece. The MPA BA is 5.2 pounds. Other than adjustable length of pull on the fly, there is not much else that chassis can do that my stock cannot. I have a Manners folding stock on the way, which is slightly heavier than my McMillan, but should still be under the five pounds that the MPA is.

Yeah, I think his comment was slightly out towards left field.

Which comment?

I would say that a timed match is the only place a chassis might have certain benefits over a stock. But that's getting into specifics. There are so many guys I've seen with a chassis that have zero intention to shoot a timed match, and never have. Then, we get to OP's question about bedding. The bedding is necessary, so in terms of accuracy, the chassis is no different than the traditional stocks out of the box. These chassis makers are telling people that bedding isn't needed, and they are flat out wrong. And as OP stated, they are telling people to double check their ammo, or the barreled action.

While cost is a different factor, I have seen chassis that cost significantly more than stocks, but what is adding the cost are add-ons and accessories, such as Arca rails. And while weight could potentially help recoil, there's gotta be a limitation to that. I mean, if that was the case, then why not flop around a F-Class rifle? Why stop at the 20 lb rifle? I've heard of matches that have stuck weight limits on rifles because of this, no?

There are other reasons to want a chassis. For some people they are more comfortable to shoot. And they are nearly indestructible. Drop it off a tower, run over it with a pickup, and the most that would likely happen to it is some scratches.

Bedding is NOT necessary. MPA guarantees 3/8ths moa on their factory built rifles, with no bedding. Would bedding improve them? Maybe, but most people don't need, and can't use, anything better than that.

I would love to see that test, but yes, I cannot argue with you in regards to durability. But I would imagine that's far and few number of consumers.

Their builds are different, we are talking about them selling chassis systems, not their complete rifles. But on their description, it shows:

Chassis – Standard BA Chassis

V-Bedding System with Additional clearance for Glass Bedding Action and Straight Section of Barrel
MPA Buttstock with Adjustable Cheek Riser, Length of Pull

Lower mounted Picatinny Rail
20 MOA Scope Rail
Cerakote Finish – Multiple Colors Available
User Locate-able Barricade stop system compatible (requires purchase of rotating barricade stop)
Built In Inclinometer leveling system

Most positional matches do not have restricted weight classes; the time, move and in some cases, the hiking kinda takes care of that.

Ironically, F-class does

Super tangent, sorry OP, but yeah, that is ironic. I was under the impression they just broke up the weights into classes.

V-Bedding System with Additional clearance for Glass Bedding Action and Straight Section of Barrel

What's hard to understand about that? They make space for you to bed it if you want, but it's not needed to be plenty accurate as is.

first that is NOT a dope card its the powder head for the magneto speed...i use a wrist coach for dopes.

second there are NO weight restrictions in the type of shooting i do and recoil management is key and a heavy gun equals an easier to manage gun especially when shooting off props...guys are running 25+ lb guns so my gun is actually not that heavy.
also as i stated i do not really like chassis's but the MPA is so versatile that you just can not beat them as far as function goes.



and my comment was not directed at YOU just a random comment.

as far as a chassis NEEDING to be bedded to be accurate...thats wrong!!

the first pic is my 6BR new barrel 10 different charge weights from 29.1g to 30.9. in .2g increments
2nd pic is my 6BRX 6 rounds off a bipod and rear bag the rest are off a bipod and my hand as rear support.

[longrange1]

heres a group at 750yds....all of these groups were shot from a BRX and or a BR and all from UNBEDDED MPA chassis's...also just a couple of weeks ago i shot a 1.5" 3 shot group on an 850yd coyote from a standing position leaning over a bench....and no im not bragging or trying to one up anyone im just saying that some chassis's do not need to be bedded to be accurate.

I can see how the weight will help with recoil management, but again, I think we are just shooting different kinds of rifle shooting, therefore school of thought is just different. And yes, now that I'm looking a tthe pictures you initially posted, I can see it's the Magnetospeed display, my bad. But I'm not sure why that would be needed.

I still don't think it NEEDS to be done to be accurate, but it will HELP make the rifle more accurate. If done correctly, it wouldn't make accuracy worse, only improve. Do all rifles need it, or would all shooters notice a difference? No, most likely not. But if the OP's action is moving that much in the chassis without bedding, are you saying it would not benefit from bedding?

I will admit needing to "hit the gym" if I were to use my F-T/R rifle in Precision Rifle events. Trying to move, acquire, and hit targets under time constraints with a 17-1/2 lb rifle ain't gonna happen with my skinny arms...

P.S.

Nice groups. When you say BRX and BR, are you referring to 6mmBR or 6mm BRX?
