Any value to looking at loads from same type gun???

[stradibarrius]

Is there any value to looking at pet loads for a specific typye of gun for example, I have a SAKO TRG22 in .308. Would asking other owners of the same gun about their pet loads provide more valuable in formation than another brand gun?
I know that each gun is an "individual" but Guns with same Manufacturing methods, same steel, same specifications be more valuable???

Somewhat, to a very small extent.

TRG mag length may allow slightly longer seating than in other rifles for example, so that would factor into more powder capacity in a case with the bullet seated further out in the case. Or Rem 700 is notorious for having along throat, so those bullets would need to be jump tolerant if fed from a mag.

But even within Sako TRG-22's you can have different barrel lengths and perhaps different twists(11:25:1 or 10:1?) if you are looking at nodes or stability functions.

So at the end of the day, someone else's TRG-22 data can give you a very close starting point, or or a decent load, but you can probably improve on it with some tweeking to your rifle. Just think on how a new lot number of a powder may/will have a slightly different burn rate than a previous lot of that same powder.....

good starting point, but each rifle may be unique (harmonics).

As noted, In general, nodes are about the same from rifle to rifle. One rifle may be 43grs for the most accurate load and another may be 43.2 grs. Seating depth often veries much more.

Even though two rifles are identical in theory one barrel may be chambered with a new reamer and another with a worn reamer. Stock differences can make for differences also. In some rifles the torquing of action screws can affect the loads.

Unless you are running exactly the same lot # of primer, powder, bullet and brand of brass the usefulness of the data is pretty minimal, IMHO.

Agreed could be a good starting point, as long as its not over max book loads. But you have to tune the load to your rifle and loading technics.

I agree that it would serve as a STARTING point. If it apeared that there was some type of pattern..say if a large number of people said the "gun" really liked a particular type of bullet as an example then it might be worth a try.
