Wish I could. I just recieved my 3 groove 300 wsm barrel 2 weeks ago. They had the it to me in less than 3 weeks from when I ordered it. I have some buddys that use them with great results. I will have results soon.
crazyhorse---I have not "personally" used them however I have a rifle that I bought from Midnightmalloy here that has a benchmark on it and it is a quality barrel and shoots great. I have also heard good things about them from others so I think you would fine to deal with them.
I have a Benchmark on my long range rig. It shoot fantastic! A true 3/8 moa or better hunting rifle using hunting bullets.
I can't speak to their work but their barrels are great in my experience.
These are the first 12 shots out of the barrel during break in at 100 yards using an unknown starter load. It was shoot-clean-shoot-clean... Started in the top left and went clockwise ending on the bottom left. (yes, it was that close to sighted in from the start!)
I got two of there barrels and they are absolutly awesome!!! I have only done barrel break in with unknown loads and were shooting tight groups. The one I got chambered in 300wsm shot four rounds into one whole during the break in process.. I also have one chambered in 6.5x47 Lapua and, my wife put 14 rounds in a .75 moa group cleaning every five rounds during break in. I can't wait to start load development with them.. I don't think you could go wrong with using them!!!! I know that when I need another barrel I will be giving them a call again...
Sent my action off today! They said they are currently running about 8 to 10 weeks, which is way faster than anyone else I spoke with. Seem like good people over the phone, very helpful and informative.
I will post results as soon as it gets back home.
Planning on adding a Manners stock and send it off to Lorenzo "Grit" for bedding and a muzzle break later this summer.
