Tikka stock pressure point removal results

[Warrigul]

Way too complicated for an unpredictable result IMO.

Much easier and I would think nearly always better to just float it.

I'd love to see an example where someone has managed to get a better result out of pressure bedding than floating a barrel.

If anyone has a link...

The technique I described involves mounting the rifle action upside down on a bench with the barrel off the edge of the bench, a weight suspended from the end of the barrel, "bending" the barrel downwards (upward in it's normal orientation) then the stock is placed onto the action with bedding material applied to the barrel channel and the stock fixed to the action.

When the bedding material has set the weight is removed and the rifle assembled as normal. the bedding material in the barrel channel applies a force equal to the weight that was acting on the barrel.

Of course a release agent is applied to the barrel prior to bedding

Is it a common mod for full timber service rifles? I know I've read an article about it, possibly in one of the service rifle pages.

Thanks...

The words "upside down" were missing...

It is not really a mod unless it is done differently to the armourers specs.

This is a whole subject by itself but just to touch on:

As standard all SMLES (should) have upward presure just back from the muzzle (supplied by a small spring), #4 rifles have pressure applied when the fore end is fitted properly(by an armourer).

Range .303's due to the heavy barrel being fitted and often neutrally bedded tightly(electrical tape seemed very popular going by quite a few that I have had apart- one was bedded with poured alloy and scraped, nothing was standard) with the copper or brass draw plates packed with brown paper. They are then free floated to the end with an overbored nose cap fitted with a grommet dampening vibrations. (these are the ones you have read about in service rifle rules- epoxy bedding, full floating etc is not allowed)

MH's also work better with upward pressure at the muzzle.

L39's and variants are also bedded differently to a #4, the Enforcer is a pure class act for bedding and apart from pulling it apart for for cleaning I have left it and will not distrurb it again as I don't think I would be able to duplicate the original workmanship.

Generally most cared for service rifles shoot acceptably and quite a few that look like dogs on the surface are very well assembled (and vice a versa). Before I fiddle I always test first, especially with range rifles.

When it comes to all other service rifles I only shoot them as I get them and don't fiddle much so although I have a swede, KAR98az, various K98's and a springfield I haven't fiddled much with them other than obvious repairs and screw tightenings. I know they rely less on hand fitting than Lee enfields and variants but are they drop ins? I will find out one day.

Actually this is so far off track that if the mods want to move it I would have no objections.

You're welcomes...

Glad we sorted that out!

It's only a very light touch at the absolute tip of the stock, that's why I was hesitant.

Only one shoot so far but results are good. Some more testing before I would look at taking it back but I think that's not going to be needed.

I had two very small points touching the barrel at the tip of the stock on my Remington which sounds similar to what you're describing.

I filed them down flat so it was fully free floating, it made no change to group size or POI.

Thanks Baldrick.

I'm going to do one more shoot for testing as is just to make sure, but I don't think I'm going to bother in the end.

Initial shoot was good though so I think no need.

Mosin nagant 91/30's also benefit from upward muzzle pressure. Mine is free floated up to the last few inches of barrel then some cork placed near the muzzle.

[dustin]

Is there a reason it's done in 3 places there and not just the whole thing?

[sha]

Just no need to do the entire barrel I expect.

[zook60]

It's only the hunter and varmint models that are fully floating. The synthetic models still touch up near the receiver.

I wouldn't bother if it shoot well just leave it. If it doesn't take it back if its still in the warranty period.

I have seen the synthetic models shoot unbelievably so I wouldn't go messing with it.

I would look at better load development or changing ammo before going down that path.

I have seen the synthetic models shoot unbelievably so I wouldn't go messing with it.

Also seen a few where people have under half MOA rifles and started dicking around with them and made them 1 MOA or worse.

If it ain't broke...
