Lots of fun, quiet and inexpensive compared to centrefire.
Excellent wind reading practice at say 100 - 200m, wind DOPE is similar to a .308

Major consideration is elevation ability on scope/mount/rail system.
There's a LOT to "dial up" once you start taking those slow little pills out long.
SK Long Range Match 22LR has already dropped 1.1 - 1.6metres (depending on your zero) at 200 as an example.
Many scope/mount combinations simply won't allow elevation correction needed.
Have fun

Wow, 385M sure would be lobbing them.

The targets were very, very small!

I reckon 50Y is too short for F class, but which targets did they use at 100Y?

Try it amd see how you comment then Rod
The X ring was about .2” and the 10 .4 “
Has to be predominantly inside to count
A line cutter was marked down not up for score
And wind will move a .22 at 50 yards!

We have been talking about doing 22 shoots at our range to encourage more people to the sport. So this topic has come up at the right time , some of the (silly) questions that I wanted to ask have been asked. The main question that I have if you shoot 22rf at 200 yds on a hexta ,it has already been answered that they register no problems, DO the projectiles all exit ETs or do some end up stuck in corflute or membrane or fall down inside and create more work for ET maintenance . Is there a velocity/energy requirement for projectiles to exit targets that anyone is aware of. Looking forward to any information that anyone has.
Cheers all,
John.

I'm sure if you search on the web @johno there would be info on energy needed by a 22LR projectile to penetrate cardboard/corflute.
Use JBM (which has been updated to include lots of 22LR data), you can get energy at target.
Eg. 40gn Match Rifle is appx 55 ft.lbs at 400 (1085fps MV, 28DegC, 60%Hum, sea level)

One thing that really needs to be considered by clubs using electronic targets - 22LR can drift a lot in gusts of wind.
If it's gusting a 22LR could easily hit a sensor, especially if a shooter really doesn't know their DOPE. i.e. goes wide and high/low

Also,
The truly horrible vertical spread on the "groups" shown in post #13 are not the ammunition.
That is a perfect example of what can go wrong with a Harris style bipod/sand sock combo if not controlled by the shooter.

For giggles here's some footage of guys scrambling eggs at 400yards.
Pretty envious of the rig on right, the Vudoo are very nice to shoot and who doesn't love seeing a 7-35ATACR on a 22LR

Would there be much of a calling to shoot sort of a rimfire "queens" event? 100, 200, 300 yards/metres. 2 classes. 15/20 shot strings. manually marked targets.

Ill give you guys a lil insight in how popular 22LR is. I'm also the Chief RO of a new smallbore club that's been built around Rimfire F-Class out to 90m. We got to over 50 new members inside of 6 months and more are joining every month. Trust me, its popular and worth running!!!!

There will be exactly that at the 2023 Tasmanian Queens, which is also our 125th Championships
