firing .22 subs and high velocity

I have a fully suppressed jw15 which i have always fired subs through. It's very very quiet which is great around my place for my family and border collie as i shoot targets quite often here.

When hunting i would prefer to use high velocity at times for more sting and range for bunnies and hares.

This may be a stupid question but is it simply a matter of adjusting the aim in height only or will i need to start from scratch when sighting in a high velocity over a sub sonic round?
If i go and buy some HV ammo, can i switch between the two types with a certain amount of clicks on height depending on what i am shooting at?

Go buy the hv ammo you intend to use and put a group onto paper then shoot a group of the sub ammo and check it. Might not need to muck around with the scope.

i have sighted it in at 40m, it'll hit high but what i don't know is will it still be straight.

probably best that i just do get a box and try it, was just curious if anyone was already doing it.

Best to try it. Each rifle is different

I just use shooter with the advertise speed minus a bit and then use the mil dots on my scope. Know what it's zeroed for each round and good to go

It may not shoot high, it may shoot low or to the side, depends on the rifle, only way to be sure is to check on a target.

Also check the supressor is able to handle hv ammo, some of them aren't and can be damaged doing so.

cool will do.

The suppressor is a hushpower full over barrel suppressor, how do i find out if that is all good for HV?

Talk to the person who sold it to you if you brought it new at a shop

MY Remington 597 shoots pretty much the same with CCI using Minimag subs or HV. The HV are slightly high, but still a dead bunny with either. Using a Hushpro suppressor

yeah they reckon it's all good.

I'll get a box and do some comparisons, will be interesting if nothing else.

Post pics of how it goes. :D

My .22lr winchester shoots subbies about an inch low out to 60 then drops fairly heavily at 80-100+

I tried out some of those CCI 'Quiet' 22LR ammunition through my old bolt action with a suppressor, dam the things are virtually silent. The projectile hitting the target sounds deafening, don't think I'd hunt with them at all though.

what speed are they? I use the winchester 42g HP which are 1024fps i think and are very quiet i think.

40g HP (I think) 700-800FPS (again, I'm not sure) Pretty much useless for anything but shortish-range target shooting.

I've had a lot of fun teaching my niece how to shoot with these on the farm. I haven't been out in awhile, think I might have to get out there!

700fps?? no wonder they are quiet, bees will be passing them haha. have you tried throwing them, ah the accuracy wouldn't be great i guess :)

Hahaha, yeah nah I definitely wouldn't do any competition shooting with em. Just for busting cans and balloons cheaply. The main reason I got them is she used to be shit scared of the sound even with hearing protection on so I tried these and she's finally got used to not flinching. She does well now can pretty much outshoot me with (her) / my Ruger 10/22 running stingers.

The way I dealt with this was to sight my Subs in very slightly high at 50m, and they dip a little by 75m. Then if you can find some HV ammo that still shoots straight (not left or right) with that zero, you will hopefully find that it's pretty good at 75m and 100m.

For my 10/22 the combo was CCI Standard for the subs, and CCI Mini Mags for the HV. CCI Stingers are about right at 100m too, but I don't find them that accurate out of my 22.

The reticle on my scope is really great for a 22. It has a circle around the center dot and the top of the circle is great for 25m and the bottom of it for 75m with subs. Very useful for this type of setup.

Those full over barrel suppressors are meant to bleed off speed so that even the standard/hv ammo comes out as subsonic. With my rifle zeroed at 75m with the Fiocchi HV ammo it is also zeroed at 50m with the PMX subs.

really? i have put a couple HV rounds through it in the past and it created the sonic boom, just no powder bang.

A mate has a savage shorty that is just like mine but it also has a ported barrel so the reduces the pace of all projectiles, think from memory i thought you're supposed to fire HV but they exit at sub sonic.

Mine doesn't have a ported barrel, just over barrel suppressor.

That projectile speed changes my response. The subs I'm using (CCI) are 1070 fps, at 700 FPS I'd say there'd be a HUUUUUGE difference between them and HV (1280 FPS)

That's good then, it gives you more options. I was initially looking at a Savage shorty, glad I didn't get it.

that's what i thought about the jw15. The shorty is quieter, first time i fired it i thought it had miss fired haha but the jw15 is more versatile as you say.

I use a suppressed JW15 with a hushpower braveheart. I have a mildot Nikko Airking gold scope and the rifle is sighted at 50m zero for WinX 40gr subs. I find that 1 dot above the crosshairs is the the point of hold under for the 40gr powerpoints without changing scope settings (effectively a 75m zero). The suppressor handles powerpoints no problems. I spotlight most friday evenings in winter using subs but have one mag in my pocket loaded with powerpoints for the possums or cats at longer range.

My jw15 with muzzle can shoots winch subsonics zeroed at 25m and then winch powerpoints are zeroed at 50m. vrry fottunate. each spot on for its best application. see if you can find a pair that does it for your gun. best not to click around with your .22 unless you only use it for field target competition I reckon.

Every rifle is different ... I couldn't get enough predictability so I have 2 x .22LR's ... one for Subs and one for HV. These ballistic tables might give you a feel for the differences. Also semi-autos can make a big difference to these charts. Down range for you is really the only way you will know for certain. Keep safe !
