Thread: 6XC with 105's. What speed?

I'm getting 3105fps with 43.2gr 2209 from a 21" barrel & outstanding accuracy.

Quickload predicts 2995 with same load and 105gr Berger VLD, but I've not tried it.

Can run some predictions for you if you want? Just PM.

Thats screaming along. You have to wonder why anyone would bother with a .243 when these results are possible with the XC

I dont have my data with me at work. I'll flick you a PM later with the details to run through Quickload. Thanks in advance

You are only getting higher velocitys than a 243 by running the 6xc case at a higher pressure remember. It's like a 6.5x47 vs a 260. The xc and x47 cases can handle more pressure without damaging the brass. It will however eat the barrel. Any 6mm with 105's @ 3k is going to chew a barrel reasonably quickly.

LJP, in Colorado we have both the good stuff and thinner air for higher velocities. Don't be jealous because we are high and can get higher.

I'm not arguing - it's a hunting rifle and I'm seriously unlikely to wear the barrel out, much as I'd like to think I might get to shoot that many animals :-)
(I'm using 95gr Berger Hunting VLD's.)

What projectile are you using?
