I just bought a 22 to practice with. Does anyone know the correct yardage (100/200) to practice from to get the closest relationship to a 308 at 1000?

Thanks, Gil Horsley
 
Oops...I meant to use 600 as the 308 yardage example. What practice yardage with a 22 would come closest to simulating that?
My wind reading skills need a lot of improvement and a friend of mine who won Camp Perry said I should practice with a 22.
 
200-250yds dependent on wind conditions. I've shot a few times at 300yds successfully but anything swirly and more than 3-5mph and you're wasting ammo IMO. What rifle did you purchase and what ammo are you intending to use? That will probably be a greater determining factor in the range you should practice at more than any other variable.
 
Thanks for the reply....I shoot my 308 in 3 x 600 all the time and trigger pulling is not my problem. I need to work on reading the wind. We don't have wind coaches in local individual matches. My friend the "hot shit" shooter who won Camp Perry and has been retired for many years suggested getting a 22 to train with. I believe his thinking was a 22 so magnified your mistakes on wind calls it would force you to learn. I just bought a CZ for that purpose.
 
Bunson, I bought a NIB CZ 453 Varmint. Ammo is CCI long rifle and Wolf Super Match.

That's a a good choice. Also look at SK Jagd standard plus as it is also made by Lapua and I've found it to be a touch more consistent lot to lot than Wolf. With rimfire you are not going to get the level of consistent ammo performance you can wring out of a centerfire. I'd start at 100yds with about a 2" circle and work your way out in 25yard increments to say 225yds and a 5"-6" target as your skills improve. One thing with rimfire is you do have to account for head and tail winds and use surveyors ribbon as your wind flags and start with several along the flightpath of the bullet. When starting out there is no reason to be guessing what's going on, use the wind flags to teach you then take the away with time.
 
For me the 22 does two things---exposes my own technique problems and helps with making wind calls.

I have a two step training program that I have sort of finally got going after lots of trial and error. My "comp" rifles are 6.5creedmoore and 308. As we all know the cost and availability of ammo or even components has gotten bad. I was fortunate to have the opportunity over the last few years to stock up on match 22 and 223 ammo so I feel pretty comfortable using that for training. So, for me I use my 40x, 10/22 and sako75 varminter in 223 for practice. All three have been set up to mimic how either the 308 or 6.5 feel when shooting. So, for me.....

1. I shoot the 22 at 50 and 100 yards to work on technique. I either shoot for groups of will do drills like the "dot drill" or the "know your limit drill" ext.
2. When I am feeling like my technique is working I will then shoot out to 175-200 yards to work on wind calls. For me, any further and the effect of the wind call starts to get lost in group dispersion from muzzle velocity discrepancy with 22 ammo.

I have sometimes access to a 600 yard range where I repeat the same sort of shooting at 200 and 600 but with a 223.

Make no mistake, I still suck at shooting! But at least its a training program I can follow which for me beats the heck out of just sending rounds down range. It also saves me not only 308/6.5 ammo but also wear and tear on those rifles.
 
I would add something :

.22lr.recoil is negligible, but you can bet it will be enough to emphasize all the shooter's faults and wrong wind evaluations, even at 50mt.,not less that any other caliber at any distance_

a quality rimfire rifle 22lr. w.quality ammos is intended as a one-holer at 50meters, therefore any group opening will be only shooter's fault_

if the rifle/ammo combo don't perform as above at this distance, aside the shooter's proficiency,the shooter will invest his time&money training himself behind a low-quality equiment, w.debatable gain_

about upper distances, the effects of all above will utterly grow, of course_

(scoped or not, don't matter)
