Brand new 7 Saum build done!

[Jakeweb09]

I had rbros rifles in Tumwater Washington put together my build, 7 Saum with proof barrel and Stiller predator action set in a Mesa altitude stock. Topped with a Zeiss v6. This was my first custom and couldn't be happier with it on initial impressions. Probably going to be a couple weeks before I make it out to shoot unfortunately but here she is. This is with rings I had laying around that are much to high but since the new ones are not in yet I had to toss it on there to just to see.

I had one built about 2 years ago as well.
M700 SS SHORT action. McSwirley SAKO HUNTER type stock...23" spiral fluted Wilson Barrel. Pretty plain vanilla as far as customs go......Boy does it shoot though. 168 Berger Classic Hunters at 2850 FPS......under 1/2 MOA out to 800 yards EVERY TIME...

Oh and here's the test target

Awesome rifle all around!

So rifle was received with a proven load shown above. But I have different brand brass and couldn't get my hands on the CCI250s right away so I took it out loaded up at 1.5 grains under proven load and worked up using fed 210m primers. On paper this was my best group. We were shooting at 200 yards with a 10mph crosswind. This was at 60.3 grains of rl26 ES of 13. Sd of 7 and average velocity of 2901. My 61.5 grain load was just a touch larger maybe .5 moa and had a ES of 5 and sd of 2. Average velocity of 2969. This was all with Berger 180 vlds. I'm going to try and make it out next weekend and repeat the exact test but with CCI250S. I'm thinking the barrel will speed up after the next 50 rounds, and put me around 3k on the higher load.

Very nice!
2,900 with a 180 VLD ain't a bad place to be...

 

[Jakeweb09]

Hoping to wind up closer to that 3k but I'm happy with 2900 if that's where the accuracy is!

Very nice build, looking forward to hearing on how it shoots and what you are shooting for a load.

Little update on this post, barrels all broke in and up to speed. The 61.5 grain load really settled in with the cci250s. Average velocity is 3006. Just under half moa is pretty standard. We were ringing a 6" plate at 650 yards last week with relative ease shooting prone off a bag. Burn ban is on here and with it is no shooting on public land. So until season opens it's back to the safe for a bit!

What FB do you run?

What FB do you run?

honestly don't know. My builder said he won't give out reamer specs, but I do know it's reamed for the 180 vlds
