Doing some research on how to best break in a rifle. (Got a new CZ455.22 LR canadian edition)

So far this is what I think:

1. Thoroughly clean the new rifle and light coat of oil
2. Go to range and zero rifle and after 50 rds clean and oil
3. Fire another 50 rds and clean again
4. After the 100 rds I think I can start to test various ammo to see what my rifle likes best.

Opinions please.
 
where are you putting the oil? you shouldn't need to oil your gun every 50rds.

I bought one of those too, and have another ss one here unshot yet.

I clean the barrel with whatever's handy last patch is g96 and let soak for 5min then patch out. I take the thing apart and have a look at all the important stuff and brake clean trigger and bolt ( take it apart too) or any shipping grease I can find then all metal gets a light coat G96 and a little bit of gun oil for the bolt and light film gun grease on lugs and bolt cocking mechanism and away we go. I usually shoot 200rds before I clean it and probably not until 500rds then seldomly unless I'm switching from copper plated to lead bullets.

I've read before that they wont shoot in till 500rds or so, so after 100 rds can start narrowing down what it prefers, ive not kept track of this myself.

Rimfires don't "break in" as a centerfire would. The CZ bore is hydraulically lapped and requires no "break in". What does need to occur, however, is seasoning of the leade area of the chamber because it is a little rough due to being cut after the lapping process. Bill Calfee refers to it as "Mother Nature doing her work", he hates to re-chamber a barrel that is shooting well because you'll have to season the leade all over again.

Opinions vary, but most will agree that new (rimfire) rifles tend to settle down after about 500-1000 rounds fired. I would suggest shooting a box of SK Standard + first just to get a baseline level of performance, then plink with whatever cheap ammo floats your boat until the round count is up above 500. You might find the rifle shoots well from the get go, if so that's great just enjoy shooting and clean as normal at the end of the day. During this time, it's not really necessary to clean while at the range, just routine maintenance at home and then ammo test again after 500 rounds. If not improved over your baseline (this is why I suggest a small test at first), shoot another 500 rounds, cheap plinking stuff, clean, and ammo test again. If all is well, the ammo test done after 1000 rounds should produce good results with some of the ammo you try.
