I really like the .243 Winchester in a 15" T/C Encore. For the past two years I have been experimenting with a buddies 15" Encore in .243. I have tested almost a dozen different loads in it so far, and to be quite honest have been quite impressed with it.
Some of the better loads are with the following bullets:
55gr. Nosler Ballistic Tips loaded with Hodgdon Varget to 3240 FPS
80gr. Speer Hot Core Spitzers loaded with H-4895 to 2920 FPR
95gr. Nosler Ballsitic Tips loaded with H-4350 to 2717 FPS
All of the above combinations will print 3/4" or less 5 shot groups at 100 yards from the bench.
Last January 1st I used this very 15" T/C Encore in .243 Winchester to harvest two Whitetail Does during South Dakota's Antlerless Deer Season. Both shots were 200 + yards. The first was a one shot kill, with the bullet entering the Deer right behind the near side shoulder, half way top to bottom. The lungs were destroyed, a rib was hit on exit leaving a 50 cent piece size exit hole. The Doe dropped in her tracks. The second one was a little different. This Doe was walking at the shot and I hit a little far back. She sprinted for about 100 yards (going right to left) and a second shot put where the first shot should have been placed put her down for the count. Bullet performance on the second shot was much like it was on the first Doe.
I have also shot a few Varmints with the 15" .243 Encore and all I can say is it is devestating.
Recoil is very managable, but with the wrong powder muzzle blast can be quite loud. The 55gr. Nosler Ballistic Tips loaded with Varget for some reason is really loud. I have also tested Federal 100gr. Power Shok Soft Points and Winchester 80gr. Pointed Soft Point Factory Ammo. Neither of these loads would print under 1 1/2" 5 shot groups from the bench out of this Encore. While I haven't tested them as yet, I want to test the Federal 80gr. Power Shok Ammo as it is now being loaded with the 80gr. Speer Hot Core Spitzer bullet that I have had such good results from over the years in a few different .243/6mm Handguns.
