Re: Best 243 bullet for deer?
I've tried many of them, here are my thoughts on what I've used that are heavy enough for deer
80gr GMX - never got it to shoot well
85gr Speer BTSP - good BC of .400, good performance with exits on yotes never used on deer.
85gr Interbond - never got it to shoot well
85gr Partition - Great performance on yotes and 1 deer, lower BC than I like
85gr Sierra BTHP gameking - very good terminal performance on several yotes and deer, great accuracy in several rifles, much lower BC than I'd like to see.
90gr Scirocco II - never got it to shoot well
90gr BT - good accuracy and small exits, yotes went right down as did deer. Little low on BC.
95gr Sierra Matchking - little expansion on broadside yotes, had runners never tried on deer
100gr Sierra Gameking - one heck of a bullet. It has shot well in every gun I've tried and has a good BC of .430. They open fast but don't blow up and put deer or yotes down really fast, they've performed real similar to what the accubonds do in my bigger guns. It will exit a yote and usually a deer, but doesn't make a huge exit. The biggest downside for me is the reduced velocity of the 100gr bullet shortening MPBR.
87 & 95 gr Berger VLD Hunting - mixed feelings. They don't expand fast enough for me on yotes, I've had lots of runners with them. They penetrate 2-3" before expanding and that's pretty deep into a broadside yote. On deer they kill very quick. Every deer I've shot or seen shot with them has gone less than 30ft and their lungs were a liquid. With a tiny entrance wound and no exit though, they wouldn't leave a blood trail on a poor shot. One deer we hauled home on the truckbed with the entrance wound down and didn't even leak blood onto the bed. The fat had sealed the wound. I've never seen one fail, but I've also never seen one hit a shoulder or major bone. I look at a 243 as a coyote/deer combo gun and probably won't use them extensively because I don't like their performance on yotes.
I have a box of the 90gr AB's on backorder. They may replace the 100gr sierra as my favorite all-around 6mm bullet. As of today I'd recommend the 100gr gameking for an all-around or deer bullet. On a side not I'd LOVE to see a 100 or 105gr accubond.
