6.5 SAUM Long Range Hunter

Guest article by Joe Comfort of Sin City Precision:

“When I first built my 6.5 SAUM it was because I wanted a rifle with more terminal energy than my 6.5 Creedmoor. The rifle would be used for big game hunting at extended ranges. The 6.5 SAUM allows me to push a 140 grain bullet to a speed of 3,167 fps with a 24” barrel. This appealed to me because I wouldn’t need to purchase different bullets, I have a 6.5mm specific suppressor and the added performance is welcomed!

My rifle is not a lightweight despite its intended use and I’m no stranger to packing into remote areas with a “heavy pig” of a gun. I did my best to avoid excess weight and carefully made my decisions on the components that would go into the rifle. I went with a Remington 700 short action receiver with one piece, magnum bolt face bolt from Pacific Tool & Gauge. To accompany the receiver I went with a Jewell HVR trigger. The barrel is a Rock Creek Sondero contour 5R 1-8” twist, this is a heavy barrel for a hunting rifle but I wanted to maintain a high level of accuracy and consistency. Because of my barrel choice I had to use products that are light and robust to finish the rifle.

I decided to use a Hensoldt ZF 4-16x56mm FF rifle scope because of the excellent optical qualities, light weight and features. The scope has a NH1 reticle with 0.1 MRAD elevation and widage turrets. The elevation turret turns CW and might take some getting used to, but wasn’t an issue for me. To mount the scope to the rifle I utilized a set of Spuhr 34mm ISMS rifle. Spuhr makes some of the highest quality rings and mounts available. They are extremely well made, strong and light. Spuhr mounts and rings also incorporate an accessory system that can be used interchangeably across their product line. This makes adding things like angle cosine indicators, red dot sights and nigh vision equipment extremely easy.

The final component in attaching a rifle scope to the Remington 700 receiver is the scope base. I had originally used an inexpensive EGW aluminum 20 MOA base which did what I needed it to do but I was unhappy with the fasteners provided. When I installed the base I torque the screws down to 40 inch pounds. When I reached that amount of torque each of the fasteners stripped! I ended up leaving them in there so I could test the rifle. When it came time to replace the scope base I purchased a Badger Ordnance 30 MOA Maximized steel base. I know steel is heavier than aluminum but I wanted something that was going to be incredibly durable and based on my past experience with their products I knew this was a proven way to go. The 30 MOA cant allows me to zero at 100 yards and have plenty of elevation remaining to shoot long range targets beyond 1,000 yards.

Now with the barreled action, base, scope and rings complete I had to decide on a muzzle device. I prefer to use muzzle brakes despite the perceived increase in noise. If I’m not shooting a rifle with a muzzle brake then chances are the rifle is suppressed. I really like shooting suppressed but I LOVE hunting suppressed. The reduced noise when firing a rifle is welcome during the hunt because it’s great for your ears! This is one area where I wasn’t able to mitigate weight as much as I would have liked. I’m using a first generation Delta P Design 6.5mm Brevis suppressor. I love the compact size and performance of the suppressor but at 20 oz. it’s heavier than I would like. The good news is Delta P Design has my solution in the form of their new Brevis II line of products featuring the Brevis II Ultra which has models as light as 7.5 ounces!

My 6.5 SAUM utilizes a Mirage ULR “Hunter” chassis/stock. I like chassis mainly because they already include bottom metal and you don’t have to bed your receiver to them. You just need to apply the proper amount of torque to the action screws, make your ergonomic adjustments and head out to the range. The Mirage ULR chassis is light, strong and incorporates additional features I appreciate. One of those features is the “Centerline” design of the chassis where the barreled action is recessed into the chassis. This keeps the rifle from feeling top heavy and gives it a great, sleek profile which aids in removing the rifle from a scabbard. The Mirage ULR chassis has all the adjustments we have come to expect in a simple, straight forward package.

The rifle has some together very well! The performance of the cartridge will put a smile on any long range shooters face and the accuracy of the rifle is only limited by the ability of the shooter. I have been working on this rifle for a couple years and am happy to see it in its almost final form. I say “almost” because there are two more things I would like to upgrade in the future. The first is a carbon wrapped barrel from Proof Research. I still want to remove as much weight from the rifle as I can and the carbon wrapped barrel is one way to do that while maintaining the accuracy and consistency I want. The second upgrade is a Delta P Design 6.5mm Brevis II Ultra HV suppressor. The suppressor is insanely light coming in at 10 ounces! These two upgrades combine will drop a noticeable amount of weight from the rifle. These upgrades will take some time and I’m not in a hurry at the moment to get them done, but I can say they are definitely in my rifles future.”
