I need another 6.5 rifle like an extra hole in the target. BUT SFRC was selling them off at $550 and I liked the look of the features.

It arrived today. I am very impressed.

Nice walnut stock. Action is bedded on a steel block.

Trigger is a crisp 2 3/4 pounds. Fully adjustable - through a hole in the trigger guard.

The magazines will take rounds up to about 2.75", so the OAL can be set to suit the chamber - not limited by the mag.

Cleaned the barrel. It had heavy oil in it, and some powder fouling. The borescope shows a quality barrel.

3 lug fat bolt. Runs very slick.

It comes with excellent irons sights. The rear sight is far enough forward that it does not interfere with scope height.

My dies and brass arrive later this week, so I will break it in on the range, zero the scope and do some preliminary load development. I have lots of powder and bullets that were used for my 260 Ackley target rifles. I am considering running the 260 Ackley reamer into this barrel.

mine arrived today. hope to get to the range fri- or sat to test the MOA garantee. Initial inspection looks good. sights look far better than the rem factory sights I'm familiar with, walnut stock is nice (but the length of pull seems a little long). The deciding factor for me was that savage arms has started selling this rifle as the Stevens 334 model so i should be able to find extra magazines if I ever loose them.
 
There is very few “new” rifles that catch my eye but that looks like a winner.
Also in the don’t need another realm but can’t rule out just one more.
Thanks for posting!

I am 6' tall, and the pull is about right for me. It looks like there is a spacer under that recoil pad that you can take out to make it a tad shorter.

That sounds like the voice of experience.

I recall getting back to my truck after a hunt and discovering the mag in my BLR was missing. It was getting dark but I retraced my steps and found the mag. I was very, very lucky.

Since then I made a point of making all my hunting mags easier to find in poor light in long grass. I have already added some striped duct tape to the ATA mags.

Still waiting for my dies and brass. Tomorrow is the day. Then I can laod some ammo to break it in, zero the iron sights and then zero the scope.

The front sight is a little fibre optic sight. It screws up and down, using a small allen key. CW is bullets Up. What a nice feature.
 
Nice score, guys! Looks like a quality rifle.

Thanks for putting your life on the line for us, Mogulrider.

You guys are making me regret not buying one!

Got my dies and brass and loaded one round and fired it. It went bang. Now I am going to look in the bore with the borescope and see how it fouls, before I clean it.

The bore has a heavy coat of soot. A few little bits of stuff. Like a barrel maker one said to me, through a borescope, the barrel looks like a bowling alley with a handful of gravel. He wanted me to clean after each of the first few shots so that the "gravel" did not get pounded into the bore surface.

I wiped the bore with one patch with Rem-Clean. It came out quite dirty. Now it is soaking after a wet patch of Wipe-Out.

On Saturday I will fire 2 break in shots (frequent cleaning) and then shoot a load development survey with 120 gr and 140 gr bullets.

As a hunting rifle, the 3 round mags are almost flush fit and are ideal for a comfortable carry. I will be shooting 10-shot matches with this rifle, so would prefer a pair of 5 rounds mags, instead of one of each.

If anyone want to trade a 5 rounder for a 3, I would love to trade. SFRC say they have 3 rounders to sell, but no 5 rounders.

I bought this rifle because it look well made and interesting. At a price of $550, I could not resist. It would make an excellent big game hunting rifle, with ballistics close to the 6.5x55 – but I have not hunted for a number of years. But if I do, this rifle with a smaller scope would be my choice of rifles.

I examined the inside of the stock and did not see any issues. The trigger was excellent. So all I had to do was break it in and get some idea of how to load for it.

On my shelf I have several thousand Sierra 142 g MatchKings and 1000 Lapua 139 gr match bullets, and a few thousand 120 g Sierra HP bullets, usually used to load for 260 Ackley and 6.5-284 target rifles. The powders used for these are a bit slow for the Creed. 4350 would be perfect, but I don’t have much of that on hand.

What I do have is lots of N150, which is cheap and slightly faster than 4350. So I decided to use N150 to load some Amax 140s and Sierra 120s to break in the barrel. I loaded 5 rounds each in 1 gr increments so that after the break in I would have an idea of what powder charge is about right.

My experience with the 6.5 caliber has been that the long bullets and long bearing surfaces can let pressure get wild. It only takes a slightly tighter throat or bore to blow primers – or worse. I once shot a rifle that could not handle the book “Start” load.

So I started each survey with a mild charge of N150. As it turned out, there was no pressure problem and the mild charges shot big groups and the hottest charge I used with each bullet shot an excellent group – so the next survey will explore the heavier charges.

I found a scope to install – a Vortex 6-24. A set of low rings gave me just enough clearance from the barrel, and it felt comfortable to shoot.

I installed the rings and set the rings just finger tight on the rifle, so I could boresight it. This worked, First shot with the scope at 50 yards was only 4” off POA.

I did not install the scope, because the rifle has iron sights. Just in case I ever hunt with the rifle, and just in case I have a scope issue, it would be nice to have zeroed irons sights as a Plan B.

At the range I started with a box of 20 rounds of ammo I loaded with brass I had earlier found in the range brass bucket. This was intended to be the initial break in ammo. I start with a regime of 1 shot and clean – x3. As I did this, I zeroed the iron sights.

The first shot at 50 yards was about 4” high right. The front sight adjusts with an allen key. I gave it one full rev counter clockwise, and the next shot was about perfect for elevation. This translates to about 1 ½ minutes of adjustment per ¼ turn of the screw. I fired another shot (after cleaning) and it went in the same hole.

I did not have a screwdriver the right size to adjust the rear sight for left-right. It has a witness mark, and I will move it if and when a hunting scope is installed.

Then I installed the scope (which had already been bore-sighted at home) and fired a pair of 3 shot groups (cleaning after each 3) to zero the scope at 50.

This finished off the break-in ammo, so I posted a target at 100 yards and proceeded to shoot up all the survey loads with the 120 gr and 140 gr bullets.

When I shoot groups, I keep notes on a diagram of my target, so that when I get home, I will know what ammo shot each group.

I cleaned after the first 20 shots and then cleaned after each subsequent 30 shots. Each time I cleaned I could see that the fouling was less each time, even though more rounds had been fired.
The 120 gr bullets were loaded to about 20 thou off the lands 2.790” This is much shorter OAL than the max length for the magazine, which is nice. But the 140 Amax were loaded to the max length for the mag – 2.850” – and were well off the rifling. When I load for accuracy development, I will choose a 140 gr bullet that is 20 thou off the rifling that will fit the mag. I am sure the Sierra 140 will fit. Maybe the 142, too.

For each bullet, the hottest round I loaded for each was the smallest group. This tells me where to explore the next time. There was no sign of pressure. The primers had nice round edges.

I have not yet chronied any loads. It is only a 22” barrel, so I expect a max velocity of around 2,600 to 2,700 fps. My 260 Ackley rifles have 32” barrels for around 2,950 fps.

When I got home I checked the bore with a borescope. Very light metal fouling that the Wipe Out made quick work of. The 3 locking lugs show uneven wear. One fully engaged, one half and one not touching. I will lap those in.

My next loading session will repeat the two hottest charges I just shot, and then more in 0.3 gr increments.

I don't consider 5 shot groups to be very conclusive of accuracy, but a 2" 5 shot group won't get any better by shooting 10 shots. 5 shot group are good for finding out what does not work. When I get some groups that look promising, i will test them with 10 shot groups.

Second range session. I tested heavier loads on N-150 with Sierra 120 HP and their new 140gr tipped GameKing. Results were a bit better.

I think I will stop load developing and just load all my brass with 39 gr for the 120 and 36 gr for the 140.

The max length to fit the mag is 2.850" The 120s are properly seated at only 2.790", so they fit just fine, but the long taper on the 140s are 40 thou off the rifling when seated at the mag max length. I will try the old 140 match king. It might fit better.

This test was 60 rounds. I cleaned after 30 and there was very little powder or metal fouling. The barrel is broken in nicely.

I decided to bed the rifle. I was doing 2 other rifles, so did this one while I was in the mood and had the gear out.

Front bedding

Rear bedding

The bedding at the rear looks thin, but I drilled a short hole in each side to give the bedding some depth and strength.

In the course of doing this, I discovered that the rear action screw was coming up through the action and hitting the bolt. I ground it down about 1/10th of an inch, and everything is now clear.

I will try the rifle out with the new bedding tomorrow.
