One of the tried and true bullets for a 6mm is the 95g nosler partition which has proved to be more accurate for me over the years than the 100g partition.
The 95g nosler partition will make a shore nuff believe out of you on large bodied deer, near and far. In Indiana, those corn fed deer can get on the large size. Also, quartering shots are very common, and you need a bone breaking bullet that can also penetrate. The 95g partition is simply awesome on how it delivers awesome shock to the internal organs and will penetrate 24" or more.
Simply stated, after shooting the 95g nosler partition, you will really begin to re think your need of a larger caliber! We shot a hot load of IMR4831 or 4350, which always gave us a 5/8" group or better.
I also like blood trails incase of a bad hit, and the partition will give you that in spades.
We hunted in Nebraska and Kansas, bucks ran 200+ lbs, and 350 yard shots was never an issue with NO bucks ever traveling over 30 yards.
Hunters today are getting sucked into buying high bc anything, this is a really bad move. Deer shots come in all angles, you need a bone breaking bullet that will also turn the gut sack into blended mess, and keep penetrating to give an exit that is spewing blood like a faucet!
The front half of a partition is soft, while the back end will not expand at all.
We killed antelope to 500 yards with the 95g partition, and while antelope are small, the bullet still expanded.
A new powder, R#26, is reported to push the heavier bullets to over 3200 fps with accuracy in the 243 and 6 Rem, now that would be an awesome combo!
I also shot cow elk with the 243 and the 95g partition, never had one run more than a couple of steps...they weighed 450 lbs or a tad better.
If you try the 95g Partition on deer, you will NEVER use another bullet, Never!
