Thread: Action strengths

I don't really know how to ask but here goes

So lets say Bob has 2 .308's ones a Marlin the others a custom rifle. Actions a Barnard or something like that

So Bob has a load in his marlin that'll blow primers and so on, if he shot that same load through his more expensive action, will the primers still blow and what not?

I guess I'm asking does the action actually stop the pressure or not? Whats makes for a strong action and does it help with anything other than not blowing up in your face where as another rifle would with too much pressure?

easy tobes , bob needs to get himself a 6.5x55

I thought Bob was a builder and I heard he shifted to Christchurch to help out with the rebuild. Probably under a lot of pressure"

A strong action isnt going to stop you blowing primers, if you are blowing primers you might be doing damage to you're non custom action and one day it might hand grenade??? I dont actually no.

I do no that a custom action is a pretty awesome piece of engineering, such tight tolerances and smooth. Will likely be a lot stiffer also so probably more accurate.

All influencing variables being equal, yes. So the two rifles would have to have the exact same headspace, twist rate, leade or throat length, chamber dimensions, land and groove dimensions etc. they would have to impart the exact same resistance to projectile movement etc. then one could reasonably expect the same result for hand loads in either. What you'd then be looking at' to account for a different result, would be action stiffness or flex, bolt lock up differences, lug sizes and engagement area etc contributing to different results.

The weaker action will be less ridged which can allow brass to stretch more and provides a less stable platform for good accuracy.
The firing pin hole will likely be larger allowing the primer to extrude into the hole at high pressures, which can lead to primer failure.
Barrel thread tenon may be smaller diameter which can mean the chamber has less resistance to radial stresses, leading to difficult extraction and other expansion issues.
These factors will have little to no effect at standard pressures, but if you want to push pressures with stronger brass, then the increased strength and tolerances of the custom action are desirable traits.

So just why did you ask this dumb arse question? Are you bored or something? Go catch me some white bait and stop this theorising on things you don't need to know!

Matt has summed it up well
Don't let some knob jokey build you a super duper magnum on a Remington action and claim it safe when it's not.........
Life's two short for those risks
If you your going two push things get a Barnard or better still back the load off.
I obvisiouly no nothing about action strength I have a blaser

Brass will always be the weakest link.
Unless its a Blaser :p

Saw the thead title on the main forum page.. thought to myself.. I bet toby started this

although, if bob could afford a banard he wouldn't have a marlin

They're all strong........till they blow up
there was a young man called swifty
who decided to reload to be thrifty
but he's in heaven you see
for when reloading 243
used bullseye instead of 4350....

I agree with @ishoot10s
All being equal they will both show the same signs but the heavier custom made action will handle the stresses, better over time.
I have seen a load show pressure in one rifle and none in another rifle of similar quality. Velocity was slightly better in the latter rifle as well.
