As I said, I didn't know if the comparison was accurate or fair. Perhaps, as KDX suggests, repetition does make what's on the internet true.Further consideration seems warranted.
A good bit of information from the net and ballistics tables that have long been available. My interest is piqued. I've never shot either round at either distance. Do any posters here shoot a .22LR at 300 yards as good practice for shooting the CF round at 1000?
Considering how very much the challenges of shooting a .22LR increases with distance, perhaps a shorter distance with it would be more useful. The following is from 6mmBR.com http://www.6mmbr.com/rimfiretactical.html
According to the information here, shooting the .22LR at 100 yards, which is at its more reasonable limits for consistent accuracy, is comparable to shooting a reasonable load of .308 at 230 yards. These ranges seem more realistic for shooters to use than the 300 and 1000 yards referred to above for practical (but not impossible or insurmountable) scope mounting reasons if nothing else.
I have no experience with using a .22LR as a trainer for CF rifle shooting. I understand a fundamental reason to use the .22LR is that it is much less expensive than CF ammo, a selling point that no doubt some shooters use to sway a tight fisted spouse into accepting the need for another rifle. Another obvious difference between the two is recoil. A shooter can shoot a .22LR for a long time without any discomfort whatsoever from recoil. Is anything lost by not using a rifle with the same recoil? I gather that wind doping skills acquired with the rimfire can be transferred to CF shooting at the appropriate ranges. What other skills can be acquired as a result of using a .22LR in place of a CF rifle?
I'm not sure why everything has to do with shooting cf...rimfire shooting can definitely be more challenging than CF at times...and most people dont have access to shooting 300 yards+. A lot of us only have access to 100 yards ranges or even 50 yard ranges. Why is everything always about CF? The whole point is to get better at being a marksman and Rimfire was invented for this purpose
