Those look like miniature ICBM’s with those long bullets.

Do you happen to know what the twist is in that barrel? Mine is certainly better with the lighter bullets.

I guess I've always considered the 6 too small to be greatly effective on whitetail. Mine does great on groundhogs with the Nosler 70gn Ballistic tips. Perhaps be ok, but if you can move a heavier BT to open up effectively, I'd recommend the 90gn or so. At 90gn, fps is crucial because of the short barrel, you should really use a chronograph to confirm you are reaching the velocity to open effectively. In the 85-90 grain range there is a large selection of great bullets available from many manufacturers, the trick is, you've got to move them fast enough to open up. I hope this helps some, but the twist will help determine what weight you can get stabilized.

During hunting season I don’t usually get any reloading done, but I found a little time this weekend to process some PPU 6.5x55 range brass I acquired this past spring. FL sized, trimmed, chamfered and deburred. It’s ready for the tumbler. I use the PPU brass in my baikal O/U 12ga/6.5x55.

6mm the 100 Sierra GK wasn't a good choice for 243 on mule deer . Degrees of dead I suppose but a dime exit didn't make me all warm and fuzzy especially at only 80 yd . I would suggest a 90 gr SP or SPBT maybe a bonded core but not anything more than that .
I feel the same way. Ive killed animals with less than spectacular bullet performance. Some people say dead is dead. I say to hell with that bullet. That reminds me of the 90lb whitetail doe I shot with 185gr Remington core lokt in an 8x57. Shot was at 65yds, muzzle velocity around 2600fps. Bullet hit a rib on the way in and lodged under the skin on the other side. The recovered bullet was 63gr. The doe died but I’ll never use that bullet again.
