Any reason to go 6.5? I am thinking about doing a 6mm creedmoor in an xlr chassis. I would use the Berger 105. The 6.5 has a bit more bullet choices but the 105 Berger is a beast

I believe the 6mm burns barrels faster, do your own research on that. I have a 6.5 SAUM in the works.

I like more a$$ on target than a 105 grain bullet. So, a 140 grain 6.5 mm is for me.

I guess a lot of that depends upon the intended purpose.

Lot of truth here. This would be a paper/steel puncher. Maybe the occasional hunt

Sounds like a 6mm creed would be one hell of a varmint gun too.

Generally, the 6mm Creedmoor and 6.5mm rounds are used for longer ranges, 600 + yards. When you get out further at distance, the little 6mm bullets become hard to spot your hits/misses. The increase in BC of the 105 compared to the previous 6mm 115 grain, and increased speed of the 105 do help it. But there is a noticeable increase in impact out at distance compared to the 6mm and 6.5mm bullets. The 6mm Creedmoor is a wind cheating, laser beam for sure.

Ahh... Misunderstood your initial comment...
That 6mm from a ballistic standpoint is insane.

Many times at long range matches the guys running 6mm really got lots of help from their fellow competitors. The 6mm would hit steel and the range officer wouldn't call "impact". Those of us that saw it would tell the R.O. "hey, he hit that". Lack of energy is why it is hard to spot. They really are a great cartridge when you boil it all down, just some of us are stubborn and stay married to our 6.5's
If you want to make a heads up comparison, just for target shooting, compare wind drift of the 6.5 mm against the 6mm. That's really the only numbers that matter in the target world. But keep it on an even playing field, 6mm Creedmoor versus 6.5 Creedmoor. Both are short actions, and both can only push their BC bullet so fast. If you run the hybrid in the 6mm, compare it against a hybrid in the 6.5mm.

Not much wind difference. But some drop differences

Why not just shoot a 115 @ 3050 and have the best of both worlds....

Both are nice, but I copied this guy's chambering and it spanks both of those easily. Link to thread I'm seeing velocity with 140gr VLD's in the 2950 fps range with very low ES.

Drop is irrelavent. The 6.5 just needs the elevation turret turned a little farther, is all.

Drop is irrelevant. The 6.5 just needs the elevation turret turned a little farther, is all. It depends, stating flatly that it is irrelevant is kind of ignorant. If it is known distance, yes you are correct. If you are ranging with your reticle, not so much. The flatter shooting option will give more margin for error.

I helped a friend get one built and it shoots extremely well. Brass choices are awesome too. One of his early group at 500 was under 1.5". Sweet round for sure. King of the 6.5's IMO.

I promise I'm not ignorant to any of it.
We're not talking about 300 yards and in, heck plenty of guys can make a .30-30 work for those ranges. We're talking about "long range" and in long range I thought we all understood the distance needs to be known. The farther the shot, the more pronounced the bullet drop. It doesn't matter what you are shooting past 500 yards, misranging by 100 or even 50 yards can cause a clean miss, even on a 2 MOA target.
Laser range finders have been around for a long time. Ranging with a reticle is a good skill to have, but only as a back-up to the laser. Having to KNOW the size of what you are ranging is impossible when it comes to living things. The military uses the 6' tall man, well what if he is 5'6" or 6'4"? They will still get a hit, but that is a hit on a human torso. Competition shooting and hunting means many of us shoot significantly smaller than that.

Flatter = more margin for error, it really is that simple. Here is a nice read for you to better understand how to use a reticle properly since you admit that for you it is impossible to range animals. It is not as precise as a laser, but will work in a pinch (speaking from experience). Link to how to range animals using mil dot reticles
