X-Bolt – The ExhaustNotes Blog

By Joe Berk

I recently posted a blog about a couple of accuracy loads for the 6.5 Creedmoor Browning X-Bolt. This blog focuses on a different Browning: A .223 Browning Micro Medallion A-Bolt. It’s the rifle you see here.

I bought the A-Bolt new from a local gun shop in southern California about 35 years ago. I paid $339 for it. It doesn’t have fancy walnut but when I saw it on the rack I asked to see it. I soon as I held it I wanted it. It just felt right. I fancied it as a walking around varmint rifle suitable for rabbits and coyotes, although I’ve never taken this rifle anywhere but the West End Gun Club 100-yard rifle range. I still make gun purchase decisions based on the kind of hunting and shooting I did 50 years ago in Texas. Someday I may get out and chase jack rabbits and coyotes with this rifle again. I can dream.

Browning offered their A-Bolt Medallion series, which were full-sized rifles, and their A-Bolt Micro Medallions, which have a shorter barrel and a shorter stock. The Browning Medallions and Micro Medallions were discontinued a few years ago when Browning shifted to the X-Bolt rifle, but you can still find the Micro Medallion A-Bolt rifle on the used gun racks and on the gun auction boards. A recent check showed that they go for around $650.

The rifle you see here is Browning’s Micro Medallion. I like the smaller size. It’s a lighter rifle and the shorter stock fits me well. I don’t like the gloss finish, but at the time it was all Browning offered (they later offered a satin finished rifle). What’s nice about the gloss finish, though, is that it has held up well. It and the deep bluing make this firearm look brand new. I like the rifle’s cut checkering and the darker fore end pistol grip tips, too. Browning made a big deal about their rifle’s short bolt angle in their advertising back in the 1980s and 1990s (bolt angle is the angle the bolt turns through to allow extraction, ejection, and loading). I like it, but if the rifle had a c0nventional bolt throw it wouldn’t have bothered me. It’s something different, but it’s not necessary. It is cool.

Fairly plain, gloss finished walnut. The Browning’s bolt throw is a short 60 degrees, much less than a conventional bolt action rifle’s 90 degrees. The rifle’s bluing is amazing.

A nice rifle. I use the notepad to keep track of which load I fire at which target.

Cut checkering on the Browning. These rifles were manufactured in Japan. They did a nice job.

The fore end tip and the pistol grip have rosewood caps. They look good.

Shortly after I bought the rifle, I mounted an inexpensive 4X Tasco scope on it. That worked okay for a couple of years and then the scope called it quits, so I bought another inexpensive 4X scope (a Nikko this time). The Nikko has held up well.

You might wonder: Why a nonvariable 4X scope? Why not the more popular 3-9X you see on most rifles? In my opinion, the 4X is a lot more useable in the field. I don’t get dramatically better groups with higher magnification scopes, and I like the lightness and the much larger field of view a 4X offers. Unfortunately, not too many companies offer fixed power 4X scopes these days. The scope companies’ marketing has convinced everyone they need variable scopes with high magnification.

The Nikko 4X scope was inexpensive. It has parallax and focus adjustments. Not the roll engraving on the receiver.

In my recent blog about the Browning maple Medallion 6.5 Creedmoor X-Bolt, I described a couple of accuracy loads I developed for that rifle. This time, my objectives were different. I wasn’t shooting the .223 Micro Medallion for accuracy. I was harvesting brass.

Bulk Remington .223 ammunition. It comes in a big plastic bag. I counted out 100 rounds for this range session.

A macro shot of the bulk Remington .223 ammo. Note the crimp applied to each round. I generally find that uncrimped ammo is more accurate with this cartridge. I think the crimping induces a bit of tilt in the bullet.

Several years ago I scoured the Internet looking for Remington brass. I’ve always had good luck with Remington brass (it lasts longer and it provides better accuracy, in my opinion). At that time and to my surprise, loaded Remington bulk ammo was cheaper than unprimed brass. For me it was a no brainer: I ordered a thousand rounds of loaded .223 Remington bulk ammo. When I need .223 brass, I’ll shoot up a bunch of the bulk ammo to get the brass.

The bulk Remington ammo was notoriously inaccurate in my Ruger Mini 14, which is the only rifle I had previously used with this ammunition. I wanted to see how the ammo would shoot in the Browning. I knew the Browning was accurate based on previous range testing at 100 yards (some of my reloads would shoot into a quarter of an inch in the Browning; I’ll give you those loads at the end of this blog).

The Remington ammo did well enough in the Browning. It held loads right around a minute and a half of angle at 100 yards, and it printed about where the scope was zeroed. Take a look:

Cheap ammo, but results that weren’t too shabby. I could hunt with this load.

This accuracy is good enough for minute of jackrabbit or coyote. The Browning Micro Medallion rifle is fun to shoot, too. It has negligible recoil, the shorter Micro Medallion barrel helps to keep the weight down, and it connects well at 100 yards.

About the accuracy loads I mentioned above: In a previous load development effort I tested .223 loads in several rifles, including two Remington 700 varmint guns with bull barrels and big scopes. To my surprise, the Micro Medallion and its 4X scope had no problem running with the big guns and their much heavier barrels and much higher magnifications. Here’s how the Micro Medallion and three other .223 rifles grouped a few years ago at 100 yards:

The Browning Micro Medallion shot half-inch groups with ARComp propellant (and it was basically a minute-of-angle rifle with nearly all other loads). I’ll reload the brass harvested from this range session with the Hornady V-Max bullet and ARComp propellant. This is great performance, especially considering the lightweight barrel and the 4X scope. It’s a great rifle.

The creek is dry and getting to the West End Gun Club is a lot easier these days, so I reloaded some 6.5 Creedmoor ammo in the brass good buddy Johnnie G sent to me. I wanted to try a couple of new loads in my maple-stocked X-Bolt.

I bought the X-bolt when I saw the wood, and it had a cross-country ride and a half to get to me. I saw it in a shop in Lamar, Colorado, and I knew I had to own the Browning as soon as I saw it. You don’t see many rifles with wood of this caliber.

There was a problem, though. The Colorado shop owner wouldn’t ship it to California. There’s an extra hoop or two a dealer has to jump through to ship a gun to California and I guess folks in Colorado aren’t basketball players. Here’s where capitalism came to the rescue. There’s a guy in Virginia who makes a living off of these kinds of situations, so I had the Colorado dealer ship it to the Virginia dealer, who then shipped it to my dealer in California. None of these dealers did so for free (going to Colorado-to-Virginia-to-California route wrapped the Browning in another $100 bill, and you can guess who had to pay up). But that’s okay. I wanted the rifle and now I have it. It really is an exquisite firearm. And it is exquisitely accurate. I’ll get to that in a minute.

I mounted a 4×12 Vortex scope on the Browning 6.5 Creedmoor. Check out the roll engraving on the receiver.

A macro shot of the receiver’s roll engraving. It’s a nice touch.

The stock has a darker wood fore end tip. It’s a classy rifle. The action is glass bedded from the factory.

The X-Bolt has a muzzle brake. The bluing is fine; that’s powder residue you see on it. I can feel a light puff a fraction of a second after the bullet leaves the barrel.

I used the Hornady 140-grain full metal jacket boat tail bullet for two loads I wanted to test; one with IMR 4350 propellant and the other with XBR 8208 propellant.

Reloaded 6.5 Creedmoor ammo with Winchester brass and the 140-grain jacketed hollow point boat tail bullet. It’s good looking ammo.

The business end of the 140-grain Hornady bullets.

The loads showed no signs of excess pressure after firing. The bolt opened easily and the primers were not flattened.

Winchester brass, and unflattened Winchester large rifle primers.

I full length resized the 6.5 Creedmoor brass because I have two rifles chambered in 6.5 Creedmoor (see our earlier story, A Tale of Two Creedmoors). The alternative approach is to neck size the brass only (which can theoretically offer improved accuracy), but when you neck size the brass the reloaded ammo will only fit into the rifle in which the brass was previously fired. I didn’t want to try to keep my ammo segregated by rifle, and as it turns out, I don’t need to. The full length resized 6.5 Creedmoor brass provided great 100-yard results in the Browning X-Bolt rifle with both the XBR 8208 and IMR 4350 loads.

The first shot of the day at the upper left target was low and to the left, which is a common occurrence when shooting from a clean and lightly oiled barrel. The next three grouped tightly into the orange target (I could see the bullet holes with the rifle’s 12X scope). I let the barrel cool for a few minutes, and then I fired another three rounds at the upper right target. I was pleased; the load returned an even tighter three shot group in about the same spot as the first group. Both groups, when measured later, were a satisfyingly tight half minute of angle.

I let the barrel cool again, and then I moved on to the IMR 4350 loads. Wow, talk about consistent. Both shot to the same part of the target, and both were exactly the same group size: 0.829 inches.

Two great 6.5 Creedmoor powders: IMR 4350 and XBR 8208.

My old RCBS powder trickler still works well.

I had read that IMR 4350 was a “go to” powder for 6.5 Creedmoor accuracy, and my results confirmed that. I had not found much information about XBR 8208 accuracy in this chambering, but it sure seemed to get the job done for me. As the above target shows, the XBR 8208 performed even better than the IMR 4350 loads. Here’s a bit more on info on these two loads:

- Both had the Hornady 140-grain bullets seated to an overall cartridge length of 2.800 inches.
- I did not crimp the bullets in place.
- I did not trim the brass for either load.
- The powder charges for both loads were weighed for every cartridge. I used my powder dispenser to drop a little bit lower charge, and then trickled in the last few grains.
- I used 31.5 grains of XBR 8208.
- I used 39.0 grains of IMR 4350.
- I used Winchester brass with Winchester large rifle primers.

So there you have it: Two great 6.5 Creedmoor loads for the Browning maple Medallion.
