Bedding a chassis gun

[longrange1]

did you tell them about the movement? and they still said its ok?
if yes id tell them i want a new chassis or my money back...if they do not step up and take care of you then id bed it i guess.

but that much movement is unacceptable and they should fix or replace it IMHO.

yeah its not...i can see a tiny bit but not like you are saying...tell them its flexing you action so bad the bolt is dragging and you want a new chassis or money back.

Mdt is assuring me I don’t need to bed. But I’m getting almost an 1/8 inch movement of the barell toward the forend as I draw down rear screw. What’s yall’s opinion?

So who are you going to believe?
The manufacturer or your own empirical evidence?

A proper bedding job NEVER hurts the accuracy/precision.
Lack of proper bedding usually hurts accuracy/precision.

And when they say you don't NEED to bed, they mean it will work without it, not that it will work it's BEST without bedding.

Shoot a few test groups before you bed and keep them for reference.
Then bed it and shoot a few more groups under as similar test conditions as possible.
Report back what you find.

Fixing it would require a redesign of the product.

Or a better product to start with.

An aluminum chassis can bend a steel action that much?

yes!

re-read Randells post #6...and next time your looking at chassis's look at how thick they are in the receiver/mag well area compared to the receiver itself.

That just shows that SOMETHING is deflecting, not necessarily the action. It could be the chassis.

is this not what we are talking about here or did i miss something?

receivers are straight the chassis is whats out.

You said

Or was that supposed to be a little white lie to tell them?

yes!...if you pay money for a chassis that is as far out as the OP states its a POS and the manufacturer should step up and take care of the problem...if the next one is that bad then they should refund your money.

i have a vudoo and 2 Curtis customs in MPA chassis and sold 2-3 others and also had an XLR and NONE of them had this type of issue.

An aluminum chassis can bend a steel action that much?

Yes.
The tang is less than 3/16" thick steel and about 3/4" wide in the stressed area while the aluminum is around 1.25" wide with an inch or more of cross section.
The aluminum section is considerably stronger than the thin steel section.

If anything (chassis OR action) is deflecting during the tightening of the action into the chassis, that's proof that the chassis is under stress that it should not be under.
