.243 is a good round. espeshaly for a yongin like your self. if your hunting envoronment involves short shots (100yds and under) i would put serious thought into the 30-30 like on the fly stated. as you can tell from my first post in this topic i was realy looking for more details on your hunting environment. if you are taking longer shots you might want to look into the .270 . its a great round. i hunt with a .270 and recoil has nothing to do with my piking this round. its just a good round.
I pondered the decision on a .243 vs 25-06 six months ago. I ended up going with the 25-06. I use the 25-06 for coyotes/deer and a .270 for deer only. Here are some pro's and con's for both cals.
1. Recoil is less than the 25-06.
2. Ballistically a very flat good long range round. (300-400 yards?)
3. Ammo is mainstream and plentiful.
4. Would not recommend to use on anything larger than deer size game.
5. Great coyote gun and good deer gun
1. Recoil is more than the .243 on the 115-120 gr bullets. Can effectively use 100 gr bullets for deer with the same/better results as the .243
2. Good consistent 400-500 yard caliber. Ballistics are superior to the .243
3. Ammo is not as mainstream and costs more than the .243
4. Great coyote/deer rifle.
Summary: I think the 25-06 has more to offer in flexibility. The caliber has been around since '69 but wildcatted since the '40-50's. Using 100gr bullets will address your recoil concerns and give you a bullet that will still get the job done. Your call but I think the 25-06 rules over the .243.
a .243 with a Hornady "light magnum" 100 gr. SST would be a great round. I would prefer a 7mm-08 Hornady "light magnum" 139 grain SST. Another good round for you would be .308 with 150 gr. SST.
They all have a MV of over 3000 and still carry enough energy at 300 yards to do the job (ref. chart) http://www.hornady.com/media/Light_M...y_Mag_Ammo.pdf
As the 7mm-08 cartridge is not readily available at the local hardware store, the .308 or .243 would probably be best.
All three have the same cartridge size and have considerably less kick than the .270 cartridge.
While you don't "feel the kick when shooting at deer" you may have a tendency to flinch more when using a larger cartridge as you get conditioned to do so at the range. just mho.
No, I don't own stock in Hornady just think these are the tightest shooting rounds off the shelf.
