I just purchased a Sako L46 in 222 on this site the other day. It hasn't even gotten to my FFL yet, but I'm all excited, and wanting to prepare to load for it. Some questions come to mind, and I'm hoping for some input. I'll give some info that I know, so you have a basis for application.
The rifle has a Hart 24" barrel with 1:14 twist. I assume the gunsmith that installed this barrel would have the information on which reamer was used (as I assume he did the chamber reaming, not Hart?), so that would tell me the neck diameter and freebore.
In the notes with the gun I see a few things: He used Lapua brass, and a .247 bushing for the necks, and the final outside diameter of loaded rounds was .248. So, my guess is the neck is a .250" diameter, otherwise there would be no clearance.

Question: is there a 'standard' reamer drawing someone might share which shows chamber dimensions with a .250" neck?
A load he liked was H322, 22.2 grains with 50 V-max bullets, with .020" jump to lands, either CCI-400 or Rem 7 1.2 primers.
My main use will be varmint hunting, but I like making little groups of holes on paper too! I'd love to finalize a load or two, probably with the 50 V-max as I have a lot on hand. And maybe a 52 grain bullet, which I'd like suggestions on which would be a good coyote or rock chuck bullet.
Is a 40 grain a good idea for this rifle? I'm curious as to why yes, or no. I have some Nosler 40 Ballistic Tip
I also have Nosler 55 FB-HP Varmageddon on hand, and Nosler 52 gr HP-BT CC bullets.
And a fair amount of Sierra 55 Blitzking and Gameking bullets.
I just have part of a pound of H322, so I searched for best potential powders for the 222 with 40, 50 and 52 grain bullets.
Some of the powders, which I actually have enough to do load development are: Win 748, LT-32, 8208-XBR, H335, RL-7, Varget, and N-133.
Ones that came up a lot, which I have, but not very much of are: H322, IMR 4198, BL-C(2), Benchmark, H4895.
Question: Suggestions on accurate loads with the Win 748, LT-32, 8208-XBR, H335, RL-7, Varget, and N-133 powders, 50 V-max, and either CCI-400 or Rem 7.5, or Fed AR Match primers?
Question: what are your best loads, powder, bullet, primer?
Question: with a 1:14 twist, what would be the best bullet weight(s) for target accuracy and shooting varmints? Suggestions on bullets to try, bullets to avoid?
I've got a lot of Hornady 53 Vmax, which seems people don't like for this gun.
Any suggestions in the 52 grain, accurate & good for varmints too?
