If you shoot a LOT, the .204 is a great yote killer.
Prarie dogs and range time will wear the 22-250's out in about 5200 rds.
Most of the calibers start to open there groups at about 5000 rds because of throat erosion due to the massive burn behind the bullets.
The .204 uses lots less powder and a lot smaller case, so the throat erosion
shouldn't be nearly as bad(I expect to get 10,000 or 12,000 rds out of mine before the groups start to spread)
For most guys that would make your barrel last through several generations
of kids and grandkids.
Excellent gun for predator hunting since it shoots so flat and fast.
Re-loading ammo won't be much of a speed advantage on this round because factory powders can't be purchased(Special blends are held as a tight secret by the factories) and the factory powder already pushes this ammo at over 4200 fps.
If you re-load, your probably not going to get your loads any better than that and stay within a safe chamber pressure.
Biggest advantage with re-loads will be the cost, should be able to get your cost down to about 20 cents per round if you hang on to your Brass.
I shoot the 40 grain bullets by Hornady called V-Max, I like them better than the 32 grain, even though you loose a little speed, it doesn't change your trajectory hardly at all and it has a better ballistic coefficient.
Right now you are fairly limited as to what you can buy ammunition wise, but that will get better as the popularity of this caliber increases(and believe me IT WILL INCREASE).
Don't have a lot of info for you yet BUT I WILL as soon as I can.
I will post my findings based on shooting the gun, as soon as I can.
