Hornady black not for bolt guns
- Thread starter Gryntch
- Start date
Any factory ammo can shoot well in any rifle, if the barrel likes it. Just because it was "designed for AR's" doesn't mean it can't/won't shoot good in a bolt gun. It just depends on if you're rifle likes it, or not.
OP: You can safely ignore everything else that your source of that information decides to share.
Hornady Black - while known as a less expensive option - will work fine in any rifle with the correct chambering. Barrels are individuals, so you'll have to test to see for yourself if it delivers the accuracy you are seeking.

Thank you the person who wrote that comment obviously doesn't know that. I don't have an AR in any caliber so I don't know anything about them
Don't own a Grendel but Hornady Black 140gr 6.5 Creedmoor has shot just fine (0.8-1.0 MOA) in multiple bolt guns for me...and available/reasonably priced at Academy.
You can shoot "gas gun ammo if you want to call it that?" In a bolt gun. Usually gas gun made/spec ammo and again I use that term loosely is loaded for pressure curves etc...to properly function a gas operated gun without overstressing the gas system or let alone not properly cycle the action during firing.
Some ammo with a given powder used for it might not be suitable for use in a gas gun.
Take a look at 30-06 superformance ammo from Hornady. I specifically asked Hornady just a few months ago if you could run this thru a M1 Garand as that was the question asked of me and my initial response was no you shouldn't as it will probably cause to high of a port pressure and possibly bend the op rod on the gun and that's pretty much the response I got back from the ballistic lab guys. They said that they wouldn't recommend that ammo for a M1G but without worries you can take they're match 30-06 ammo that was spec'd and loaded for a M1G and run it thru a bolt gun.

You have to be careful what you read on the internet…Lots of morons out there giving bad advice, or talking out of their asses on things they have no clue about. Luckily, this forum tends to have much more knowledgeable folks (and even industry professionals) who regularly post and frequent it, so you have a much better chance of getting accurate information here, than most of the other forums out there.
Based on the ONE caliber I tried in the ONE bolt action rifle I tried it in, I would 100% agree. 
It shot horrible.
But I wouldn't go making any broad proclamations based on that though.

Since it's likely loaded to safe pressure for a Grendel AR, don't expect it to reliably cycle in a bolt gun.
You will have to manually cycle the bolt

That 168 load shoots great in both my semiautomatic LMT and my bolt FN PBR.
In fact it has less POI deviation between suppressed and unsuppressed. No idea why but it is what it is.
FGMM shoots slightly tighter groups but has much more deviation in POI between can vs no can. At least in my two 7.62 rifles. Small sample obviously.

Has shot quite well for me in 3 calibers in bolt guns.
In fact, the .308 Black with 155 AMAX is really good and piles deer up with ease with a bone stock Tikka

The bending of the OP rod in a Garand is the biggest BS story someone ever started. SHOW ME ONE that has been bent by shooting 3006 in a Garand. Frank You know your stuff but please do not repeat this BS. It is NOT true and will never happen.
Finally got my ballistician to do a comment about our testing various different milsurp and commercial ammo in/for the garand to disprove the longstanding M2 ball only myth.
His comments are below...

I....have been meaning to write a book about this. From my earliest days of being a DCM shooter of M1 Garands on the weekends, to being mentored by old Marines, to being an AMU shooter, to working in Technical Services and Research and Development at St. Marks Powder.....to eventually owning and operating my own internal ballistics laboratory....I have heard of the "theory" of the bent-op rod in the M-1 Garand.
...in the early 2000's, I befriended OLD engineers from Rock Island, Winchester, CCI, and other government and industry locations. NONE of them could confirm "the theory". NONE of them had ever SEEN a bent op-rod. Despite all the parroting, the claims, the "assurances" from crusty old M-1 Garand shooters....even the oft quoted "This ammo is MADE for the M-1 Garand".....
So, being in the position of owning a SAAMI member laboratory, and having every means to run a thorough test....I did.
There are a LOT of nuances involved in ballistic testing. And honestly, if you REALLY want to challenge me on knowledge....bring your lunch. So, I'm not going to get into the "50,000 psi discussion". You quote that in an argument, and you clearly are an arm-chair Ballistician, without modern day knowledge. Study up.
Just a few Cliff notes, before I do the data-dump: I made a "blue pill" load, that approximated the current "Maximum Probable Sample Mean" for 30-06 Springfield SAAMI ammunition. This is the HIGHEST "production" pressure, as statistically suggested within SAAMI documentation for piezo transducer testing. That pressure (MPSM) is 63,800 psi. Note: Max Average Pressure (MAP) for 30-06 Springfield is listed at 60,000 psi Piezo...The intent of this portion of the exercise was to attempt to maximize PORT pressure, while keeping CHAMBER pressure within the realm of "safe limits". Surely, all would agree that IF chamber pressure were pushed FAR above "normal limits"....any damned fool could break a gun, in any number of places.
Back to the maximization of PORT pressures, just to drive the point home: The intent was to find ANY combination of projectile and propellant that would MAXIMIZE port pressure, while keeping inside "reasonably safe" SAAMI chamber pressures. Some would believe it would be "heavy bullet"....and some would believe it would be "slow powder". Well....I ran that experiment for days...turns out a little 130 grain bullet, with 70 (SEVENTY) grains of a fairly slow propellant DID maximize port pressure. Higher than any heavy bullet did....
A formal test barrel was fabricated by SATERN barrels, conforming to the min-spec dimensions of a 30-06 government test barrel chamber, bore cross-section, and port location from the muzzle. While not a "SAAMI" test barrel (but rather conforming to government drawings), it met the intent of the program. Using this test barrel, I created the "blue pill"....and tested ALL ammunition lots of both government and commercial 30-06 ammunition.
Surely some here will reference a group of gentlemen who DID instrument a true M-1 Garand with a piezo transducer TO THE GAS PORT CYLINDER of an M-1 Garand. And...they reported pressure results. Mmmmmyep. Good for them. I did that too. But I did not report those numbers, as there is NO standardized method or equipment to test/capture those numbers. Suffice it to say, that when taking into account PV=nRT, any VARIANCE IN VOLUME of the cylinder will drastically affect the recorded pressure output. Thus, the gas-port cylinder test is inherently flawed, when compared to standard industry methods. MY pressure output numbers utilized industry-standard methods, whereby the pressure is read DIRECTLY at the location of the port (as-per EPVAT modern day methodology), with no associated "free volume" to dampen the output results.
An M-1 Garand rifle was purchased from CMP, with both a "service" grade barrel, as well as a new Criterion barrel...several trigger groups, several op-rods...all with the intent to destroy this firearm by shooting the "blue pill" through it repeatedly.
Findings:
Folks have claimed (totally incorrectly) that heavy bullets....or slow powders....or SAAMI MAP pressures....will doom your M-1 Garand to certain destruction. Folks- I have passed my results to other SAAMI member laboratories, and major ammunition manufacturers. All of them have told me that they've never witnessed ANYONE ELSE, EVER test this system so exhaustively.
The "Blue Pill" load did NOT destroy any part of the M-1 Garand. I've fired in excess of 200 "Blue Pill" rounds through it (along with every other type of commercial and government ammunition), and there remains NO sign of fatigue, or of failure to feed/fire/extract. I have also fired hundreds of rounds of 200+ grain projectiles through this rifle. NO PROBLEM, if the load is kept to SAAMI pressures.
The M-1 Garand is a ROBUST firearm design, able to digest standard SAAMI modern-day ammunition, of any make, and any components, when loaded to SAAMI standard pressures.
I have long offered a bounty for a bent or broken op-rod. I NEED to examine one...but no-one has ever EVER claimed to have had one. The constraints: It must have bent or broken with a load that conforms to SAAMI chamber pressures. The op-rod must be of original non-altered condition (before it was bent). If a hand-load, I must be provided the reloading recipe.
Despite my better judgement, the attachment provides EVERYONE my raw data, proving the extent of the testing across the ocean of time, disparity of manufacturers, and methods of pressure generation. Everything herein is fired out of the pressure barrel, using modern day piezo electric transducers of industry standard, filtered low-pass Bessel active at 20kHz, the transducers and charge amps all calibrated with a dead-weight tested.

Folks- PowderMonkey here again (Ken Johnson of Prospector Training, LLC). We found the attached results sheet containing more data than before. I attach it here, for historical perusal. Should anyone wish to use this information for commercial purposes, I ask (kindly) that they contribute to making me whole. I may be found on the internet, or in Crawfordville, FL.
Jeremy Cheek and I performed this testing at the laboratory. We utilized many of his M1 and M2 lots, dating all the way back to...1927! He freely donated this ammunition, so that others might be able to better understand the TRUTH of the M1 Garand, ammunition loaded and certified for the weapon (over many years), as well as modern day alternatives.

I’ve shot black in 2 different 6CM rifles and have had pretty good luck with it. Might be marketed towards gas guns, but it’s dang sure not exclusive to them.
Late to the party as I was told the Hornady Black line is a special retail package for certain retailers. Black 6.5CM 140 flavor is the same as the American Gunner 140.
