I bought a Ruger #1V in 220 Swift. It has a heavy 26" barrel. They do heat up the barrel pretty quick but while it is cooling off I shoot a .223 Winchester Heavy Varmint.
Although H335 is very popular with the 40 gr vmax
Give Benchmark a try before you make up your mind.

I like to do my hunting BEFORE I pull the trigger!
There is only one kind of dead, but there are many different kinds of wounded.
