Change stock: redo loads due to change in harmonics?

[capreppy]

Simple question. If you change stocks, does barrel harmonics change requiring a redo of load development?

There could be some change in impact, especially if the new stock is not fitted properly.

My experiance was with a Savage 12 factory pillar bedded free floated barrel, to a Bell and Carlson pillar bedded flaoted barrel, and a Choate Ultra Varmint full aluminum bed free float barrel.

Neither change caused me to rework loads but rather a simple recollimation of the scope, ( same scope, rings and mount used in all three applications) and shooting the new settings in.

I can live with a change in POI as I would need to rezero the rifle anyway in the new stock (the new stock will require higher rings and a different scope mount).

Just wanting to confirm as someone on another board indicated otherwise and I had to think about it.

I am mid stream on a build. I thought I was going to have to wait 11 weeks on my barrel, but the vendor said he'll have some in stock this week and it'll ship towards the end of the week. The stock however is still 7 weeks out.

I was thinking about picking up one of Boyd's Centerfire Tacticool stocks (at $109 it is an inexepensive way to get up and shooting) to get this build done so I can get to load development. Plus I want some time behind the new barrel and the new scope for this build.

The short answer is 'it depends".

A simple stock swap where nothing else changes you would probably only see a point of impact change.

But no change is as simple as it seems. You will not know until you shoot the rifle. Do not get invested in lots of a particular reload until you know how the rifle will shoot it after the build.

And before you pull down your loads, experiment with the torque on the action screws.

My goal is to try and narrow down accuracy loads. I will probably do a final tuning once the action is in the stock it will stay in anyway, but want to make sure that the accuracy nodes aren't going to change dramatically. A .1 gr change in charge will be caught by a final tuning, but a .5 or greater change in charge may not be caught.

$109 bucks is a great reason to try out one of Boyds stocks.

I couldn't stand the weight of the Choate stock, found the B&C Carbelite on sale and it turned out to be a good deal was able to sell the Choate and about broke even.

My Ruger 308 Win MKII M77VT,and my Savge Model 40 Varmint Hunter both have Boyds laminate stocks on them, very good quality, can't see why one of their synthetics wouldn't be a good buy.

Keep us updated !

I've got a Choate Ultimate Sniper on my 223 (stagger fed) and yes it is heavy. It will serve as a trainer for the new build.

I've had Boyd's stocks before and yes for $109 to get me up and running, it is definitely worth it.

I would glass bed the action too, good tight prefect fit on action ,barrel lug will help the harmonics flow through stock and barrel.

The new stock is an XLR Chassis. I probably won't take the time to bed the Boyd's as a different action will go in that if I decide to use in the future.
