Rimfire scope zeroing

[Ratman2 2]

I'm an experienced airgun and shotgun user but I'm a rimfire virgin I bought a new CZ Varmint on the 21st of December but have been too ill with this bird flu that's going round to use it.

I plan to build a back stop out of straw bales, two deep, and use a piece of chipboard 3/4" thick to pin targets on to zero my scope, I'm going to zero at 70yds.

My question is....do you think my plan for a back stop is suitable. I'm going to be zeroing on one of my permissions and will be aiming down 3/4 of a mile clear land and will be useing Winchester subs.

As I say, I'm a virgin so please be gentle with me.

A good earth bank is always the best plan BUT as long as you are flat, even if it goes clean through everything it will ground long before 3/4 mile. Depends of the quality and dampmess of your chipboard, but even with subs it is likely to go through the chipboard. By the time you bring the zero in and put a couple close to each other it will definately go clean through the chipboard!

Yup.it will go through chipboard for sure. I was zeroing at 50 yards,using targets pinned to wooden battens at least a inch and a half thick. They were leaning on a old paraffin tank which kept clanging as the bullets went through. Went through the tank too,where about 3 had hit the same spot.

Solids or HP subs both penetrated about the same, but the HP's left a big exit hole. Double straw bales should slow them up though.

the chipboard wont have any affect on the bullets as i have shot through 3" fence posts at 20 yards. what size of bales would you be using? i also usually use an earth bank as a back stop. if i never had the earth bank as my back stop i would get hold of one of the builder merchants 1tonne bags and make my own

Thanks to all who have replied so far.

I intend to use small straw bales, two wide, three high and two deep, 3/4" chip board in front to fasten targets on and how about as an extra, 3/4" plywood at the rear of the bales.

hi i use winchester subs 100yards spot on i tried at 200 it was 7 feet drop if your firing flat at 100 it will hit the ground be four 200

Thanks for that, I recon that the straw bales should absorb a fair bit of velocity and the slugs should ground well within my shooting range.

At what distance have you zeroed your scope.

we use a round hay bale(stood end up) for our backstop more than enough for rimfire even at close range 25yds

On the safety side, and as regards backstops you really cannot be TOO safe, but the plans you have outlined for zeroing sub sonic ammo seem appropriate.

 

A Winchester sub has plenty of power left to kill a rabbit at 200 yards. Problem is hitting them when you are out in the field; 200 yard subsonic quarry shots should not be considered with a .22LR. Most people will zero subs between about 50-75 yards and supersonic .22LR between about 60-100yards. It will depend on your knowledge and usage of the gun, and the land and quarry you are shooting at. Mine is zeroed at 75 yards with CCI velocitors which equates to 50 yards with Magtech Subs...so I don't have to keep playing with the scope when I change ammo.

Now that's a good idea Landrover and I'm going to use it, thank you.

Update

I got one of these bales today, farmer loaded it into my trailer and I towed it into the field, left it in the trailer, used 4" nails to pin the targets to the bale and off I went, took six shots to zero at 35yds then moved back to 70 yds and zeroed again.

Such a good idea Landrover , thanks again mate, it's saved me no end of work. Have one on me

[landrover 6]

nice to be able to help, we also put a piece of plywood in front to pin the target to easyer than the nails ,all the best for 2008
