Cummins..... If you are looking to get a rifle built, look no further than Insite Arms. They are absolutely top notch!!! The Guys there are friendly and have tremendous experience with building rifles ( the right way!!), for long range shooting, hunting and any other style of shooting you do.
I recently had Harley re-barrel my HS Precision HTR Short action in a 6.5x47 Lapua. I asked Harley to provide a MTU diameter barrel and build away. Shortly after I got a call from Him saying that he bore scoped the barrel before starting to build and noticed some porosity in the barrel, he then returned the barrel to the manufacture and had them send out a new replacement......Tell me what gunsmith would do that????
They also build the Heathen Brake that I had Harley install on this rifle (just in case I get the chance to shoot PRS). With it you can spot hits at 400 yards on steel targets...( Amazing piece of kit). He also does an absolute bang up job on cera-coating to, which he has applied to 4 of my rifles, and last but not least he let me take a look at the chambering job, with the bore scope, before I left the shop......Again, who does that??
Once I got the rifle, I loaded up some test ammo and went to break in the barrel. All of the test loads I shot were under 1/2" at 100 yards. Once I started to narrow down the charge and tune the load, it was pointless to shoot groups at 100 yards....couldn't tell which load was better!!!! so I moved to 200 to see if there as a load that stood out....
I finally settled on 40.2 gr of H4350, and the 140 Berger Hybrid. See final test group below. Thats a .209 MOA group off a bipod...5 rounds at 200 yards!!!!
And to top it off, I shot at our F-CLass May Long weekend shoot these past 2 days. I was totally impressed with the way the rifle shot and handled. I haven't shot F-Class competitively for the last few years so my wind reading skills were a bit rusty to say the least....but with this rifle it was so much easier. The V-Bull in the centre his 1/2 MOA.. 3" @ 600 and 4" @800
Here is the 600 Yard data card:
And the 800 yard from today:
So as you can see its pointless to go see anyone else to build you a Super accurate rifle. I usually stop in at Insight arms to say Hi when I go through Lloyd......and have seen test targets of the rifles Harley has built for his customers.......out of the 12-15 test targets he has shown me, the worst.....and I mean the worst group I have seen, was from a .338 Lapua AI....and that rifle only shot a mediocre 5 round group under 3/8" MOA. I have seen groups from some of Insites rifles that will shoot MINUTE OF DECK SCREW???!!!! WTH is that you ask......how bout 7 rounds at 100 yards that you can cover with the head of a deck screw. Can you say WOW!!! This is the kind of quality you get from Insite Arms. And these are full out Tac / long range rifles...not bench rest builds
Hope this helps make your choice of gunsmith a lot easier.....Do yourself a favour and give Insite a call, they will be getting my next build!!!
