Thread: Drop chart subsonic 22

Jase, pinecones @ 200m using Marlin 795 22lr and CCI Subs. Get Burris Signature Zee rings with an offset kit or a MOA rail, gives you more dial.

The furtherest here is 143m. The back of the image is 160m and we got some the next evening out at that distance. A rare couple of windless evenings.

thats awesome, anyone know the BC of a winchester subbie?
this is just for a play, im not expecting much from the humble 22

There was a list of bc for 22lr ammo somewhere, may have been ken roundtree or rimfire central.
Or just use the cci one for a start and adjust from there.

Good suggestion ebf I replaced the rings on my 22LR with some CZ ones (rings with bases). Malcolm put two 0.010" shims between the rear ring and base and lapped the rings to suit. This means my 50m zero is less than a full revelution from the bottom of the scope and i can dial the 29MOA required to get my 22LR to 200m. Turns out my Sako Quad Varmint is still shooting less than MOA out to 200m!!

General question though, I suspect most supersonic ammunition will go transonic, then subsonic well within 100m. Do you think this will make much difference in accuracy at longer distance?

There is a 22LR long range (<200yds) competition shoot coming up in a couple of months. I was wondering if i should be looking at supersonic ammunition.

In my unscientific testing with one 22 only it definitely shoots better +100 (with the subs)
Weather this is due to dropping threw the sound barrier or just better es of the subs i don't know

Gillie, I have played with subs and velocitor a out to 200. Not seeing a massive difference in terms of accuracy, but then again 22 heads are not exactly up there in terms of BC !

For shooting at live things, I would use the velocitors, the 40gr gives it a lot more retained velocity and punch. Stingers are faster initially, but if I remember correctly they also run out of steam faster.

Cheers guys, i have just ordered another couple of bricks of subsonics so i'll continue with those.

Do you think i should be setting up my drop charts with atmospheric condition variations as well?

A good starting point for long range .22 is the .22 point blank sighting-in sticky that I did for the other site.

Is it worth re-publishing it here as a sticky?

I'm testing out my to-be LR .22 this weekend if the weather is ok. I chronied a bunch of .22 loads through a mates Savage MKII last weekend, found it all to be pretty inconsistent. This is with a 22" barrel though, I will probably cut mine back to 16" to reduce the extreme spread in speed. I've also wondered about HV ammo, does it yaw/tumble when it goes transonic? Someone should make some nice long pointy .22 bullets.

there is a top thread on the other forum iv stumbled across,

FishnHunt - New Zealands Famous Hunting and Fishing Forum Since 1995 - long range .22 shooting

some of these boys are taking it to the extream

What G1 BC are you using for the Winnie ammo - .118 ????

You must have the thing sighted in for 150yds or something!

Here are the verified drops for my old smallbore gun using SK Match subs:

Went out and shot at the gong @ 220 yards with CCI subs out of the Ruger 10/22 today in gusty wind.

I got 3 shots out of 9 on the gong , he got 3 /9 as well

Good fun
