Often the ammo maker's website will specify BC. Sometimes the online ammo vendor will specify this. They may or may not specify DC. I assume a DC of G1 unless it is specified in writing as G7. I don't have a chronograph and trust published data on ammunition. I love Hornady's online ballistic calculator.Hardest part of figuring this out is finding the BC of the bullet your using. I did this a couple years ago with my 22 mag. Found the BC somewhere on the internet for a 40gr bullet. If I remember right it's .094. Ran it MPBR at a 4" target and got 151yds. At 151 yds it's 2.1" low and at 75 yds it's 2" high. Idea was to figure out how to best use it as a calling gun for coyote's. Deal that got me to do this was seeing only the head of a coyote in a tall grass field. Guessed the head would give me a 3" or maybe 4" target. Now that I have it, I've never used it but I have shot the distances on range against what my chronograph told me and it was right on the money! Looked at my 22 mag in a whole new light after doing it.
Now don't know but suspect that the BC of the 40gr 22LR round might also be .094 also. What screwed me up was after I did this I went out to stock up on 22 Mag ammo and about all I could find was the 34gr loads. Right now I have about five hundred rounds of the 40 gr stuff and don't plink a lot with it!
BTW. The velocity according to my chronograph at 151 yds is 1191 fps. MV was 2000 fps.
What the hell........
OP, I think you are trying to do too much with a single rifle. A 22 is probably the most common rifle/pistol round in the country and IMO, the best choice for small game inside 50 yards. I shoot for fun out to 100 yards with mine and have grouped fine. FWIW, I have both the CZ and a 10/22, both of which shoot extremely well at my sight in distance of 25 yards. I did shoot a fox last fall at around 70 yards with my 10/22.
I've no experience with any 17 cal but I have read they are more susceptible to wind drift.
Much beyond 50 yards you would be better off with a 22 Mag for prairie dogs or step up to a Hornet, 204, 223, 22-250, etc.
I used to hunt ground hogs here in Pa a lot so I had a 22-250 for long distance and 22 Mag for 150 yards or less.
I like guns of all types but when looking for a particular application, I'll take functionality over looks every time.
Ya know, I've never shot the info in my Hornady book against my reloads. If I can remember I need to try that this spring! Be interesting.Often the ammo maker's website will specify BC.
