7.62x39 vs .243Win.?

Depends on what the application is and in some respects the type of ammo used for both calibers. Your question (if I read it correctly) is not easy to answer without more information.

For shooting paper, no difference. For shooting deer, the 243 wins hands down.

Hi.
On what distance .243Win. 7.62x39 will recover (100m.-200m.-300m.)?
Absolute decline of these calibers on distance 200 meters practically identically.
Energiya higher at 7.62x39.
P.S.
In all of situations we examine a standard bullet for SKS 123gr.-124gr. and 100gr.-110gr. for .243Win..

Exactly ! :)
 
For the 234 Win at 100 yards using a Sierra 100 grain HP using a nominal 3200 FPS for muzzle velocity we get 1809 ft/lb of energy. At 200 yards: 1420 and 300 yards 1129. For the 7.62x39mm at 100 yards using a muzzle velocity of 2300 fps with a Hornady 123 grain SP bullet we get 1104 ft/lb of energy, at 200: 831, 300: 621. So, at about 167 yards with the 7.62x39mm we dip below 900 ft/lb of energy, which is (what I have heard anyways) is a good cutoff for deer sized animals.

All data was gleaned from Sierra's Infinity program, version 6.

say kristian55, are you asking as you plan to hunt with a 7.62x39 or is this one of those zombie apocalypse questions?

Hi.
I need to fill an interval 7.62x39 and 30-06.
"...zombie apocalypse questions?"-Yes,all of habitants of the former USSR a bit RISKY people.:ar15:
 
You can have a used Stevens 200 in .243 with a decent optic for a little more than the price of an SKS. Unless you're pushing bush, ALL the time, which IMHO is all an SKS is good for I'd go with the .243. All that ballistics BS you generated, can be negated with SHOT PLACEMENT. POI with any decent .243 bolt will be much more predicatable than the 'barndoor @ 100yds' accuracy of the typical SKS. But, whatever floats your kayak...
 
Hi friends.
A question is based on a desire to fill a niche between calibers 7.62x39 and 30-06.
In relation to application of this caliber - I search most "universal"
CXP1,CXP2-on long and middle distances and CXP3 on short distances.

i'd say the 308 fills that gap nicely if that is what you are trying to do.
