Question for FAC holders....

[burntout]

Coming from an airgun and now shotgun background I know little about rimfire rifles, or more relevantly bullet trajectory.

 

Does a .22, .17hmr etc have a relatively flat trajectory? What sort of range are they typically zeroed at and what sort of holdover would be expected at say 120yards if you zeroed it for 60 yards?

 

Cheers

22 not really 17 HMR flat as pancake

 

typically zero 22 @ 60 Yards

 

17 HMR whatever you like really- mines zeroed at 100 yards and I rarely shoot out further than 150 yards- some people say 35 yards is optimum for 17 HMR I use the 100 as its suits my shooting

 

22LR @ 60 yards is ok however should you wish to shoot this cailbre at say 70, 80,or 90 yards then a mill dot scope is req for working out hold over etc - just like a 22 air rifle- simples

My HMR was zero'd for 125 yards, so take that for what it is. I didn't hold under or over on headshots all the way out to 135 or so.

 

My 22LR is zero'd for 60 with a mil-dot scope. At 120, I'm on the third mil-dot down, so about 10" of drop. Realistically, I can only shoot that with the 22LR at big targets (body shots on hares/rabbits and crows/pigeons) on calm days. In practice, there is always enough wind up here that I don't shoot that far. More realistically I keep my 22 to 60-80 yards max.

 

Thanks,

Its a good excuse to practice.

I zero my hmr at 100yrds and dont hold off at anything under that distance. It shoots 1" low at 125yrds, 2.5" low at 150 yrds, 5" low at 175yrds and anything over that I'd miss anyway!

This is using hornady vmax in a CZ452.

All you can really do is practice, practice, practice. Get to know your gun, learn to use it safely, and don't try and out do yourself. Try making a few target boards, set them at different distances and see where you need to correct your aim [i.e hold over/hold under].

There is no substitute for experience, so get out there and get some.

I personally don't like milldot as i find different scopes at different mags can alter the point of impact, i much prefer trying to guesstimate the hold over in inches which so far is very successful.

for example, my 22lr is zeroed at 70yds, at 20yds i hold 1.5" under, at 50yds 1" under, at 100 yds 2" over, this is with a hawke 3-9x50 on medium mounts.

my 17hmr doesn't get used much but is zeroed at 100yds and i only tend to shoot stuff thats within 30yds +/- that distance, so not much need to calculate any hold over/holdunder as it's still pretty flat at those distances.

good luck and get practicing

Good advice there....no so relevent for me as I dont have one / are not planning on getting one at the moment - it was more of a general question.

.22lr with subs is a bit of a Rainbow, (but looks excellent if you move up from 12ft lb air rifle) the HMR with 17 ballistic tips is pretty flat within it's useful range.

 

Mine is zeroed to 100 and is easy 20-25 yards either side of that, actually it's pretty easy all the way up to that!!

 

I heard talk a few months back that 125 yard zero is worth thing about as it gives a slightly wider useable band without adjustment...not tried yet but may well do!!
