[N310toN170]

So, with the Remington $75 mail in rebate, I picked up an SPS Varmint in .204. The question is now, what barrel to put on it to make the .300/WTF?

The AAC prefit has been out for awhile, any thoughts as to quality and accuracy? Are there advantages or disadvantages of the prefit chamber and having to headspace from the recoil lug?

Or do you just go with a known barrel maker (Shilen, Krieger, Douglas, et al) and use a .300 BLK; .300/WTF reamer?

If a custom barrel is used... Does anyone have experience using the 5R or C type grooves with subsonics? I've used my 5R .308 for a few loads subsonic and was quite impressed but didn't know how that may carry over to .300/.

Your input is greatly appreciated, as always!
