Short answer...

Inside of 250 yards you'll never know the difference, they both kill deer very well...Which does his gun group better???

Here is my longer version...I bought a Ruger M-77 in 1980, since then it has been my only center fire rifle...I've probably killed 300+ deer with this gun...I started with CoreLokts, sighted in 2 inches high at 100 yards and from 1980-1998 or so that's all I used...

Well, as we had more advances in bullets during that period and premium loadings came out by several companies me and 2 buddies who all shot .243s decided to try each loading on several deer to see what did the best job...

One of these loadings we tried was the Federal Premium 85gr Sierra GameKing BTHP...When told of this loading we thought it was a groundhog load, we were told it was for deer...In a nutshell, it is a deer bullet...

I killed 3-4 deer with it one week and had great success...I even called Sierra and talked with them...This is no average hollowpoint...The lead on the inside is harder than most and the jacket thicker so it has more controled expansion than that of other hollowpoints...I have killed 25 or so deer with it and my buddies have killed another 25 or so...It works well...

Now, this is the bullet for long range shooting with a .243...It's muzzle velicity is listed at 3330 fps...In my rifle, when sighted in 2 1/2-3 inches high at 100 yards it is about 3 inches low at 300 yards...

But, as mentioned at the beginning, I've killed deer out to 250+ with a plain old 100gr CoreLokts...So, if most shooting is done within that range they work fine as well and they are much cheaper...I still have some of those Federal loadings and use them from time to time...Back 10 years ago they ran about $18 a box and CoreLokts were $12 a box...

Federals are pushing $30 a box I can catch CoreLokts on sale for about $15 a box...
