This can be very important — even life-saving. For example, with a hang fire, i.e. a round that does not fire immediately, it is vital to keep the gun pointed DOWN-RANGE. And with a squib load, which may have left a round inside the barrel, it is vital to UNLOAD and NOT take another shot! If you did, the gun could blow up in your hand when the second, full-charge bullet hits the trapped bullet.
The Five Topics Covered Are:
Misfeed (aka Tip-Up)
Double Feed
Stovepipe (Failure to Extract)
Misfire / Hangfire
Squib Load
1. Misfeed or Tip-Up: With any misfeed you should stop firing. With the muzzle pointed safely down-range, remove the magazine, then pull the slide back and remove the round that did not feed. Check the slide for dirt, debris, and check the round that did not feed. After re-inserting the magazine, make sure the mag is seated properly.
2. Double-Feed: This is a fairly common issue with some gun types with worn springs or cheap magazines. Again you want to remove the magazine. CTD states: “Remove the magazine and cycle the action until your double-fed rounds fall out — always keeping the muzzle pointed in a safe direction[.]”
3. Stove-Pipe: This occurs when the case of a fired round does not eject fully. There can be many causes — damaged extractor, low-pressure powder charge, dirty chamber, or greasy cartridge brass. In addition the issue is common with old, worn-out recoil springs. To avoid Stove-Pipes, replace the recoil spring every 4000 rounds, and make sure your chamber is clean and the extractor is not chipped or damaged.
4. Misfires and Hang-Fires: There are multiple causes for misfires (“click no bang”) and hang-fires (slow ignition). There can be a defective primer, the firing pin could be damaged, the powder many have been bad, or the case not filled properly. With a misfire, keep the gun pointed down-range at least one minute. If the case does not fire, eject it but leave it on the ground. With a hang-fire (delayed ignition after firing pin strike), keep the gun pointed down-range, then drop the magazine and eject the (new) unfired cartridge in the chamber and inspect the gun when completely empty.
5. Squib Load: A squib load is when the gun fires, but the actual case ignition is very light with little noise, smoke, or recoil. This can be because the case had a primer but no powder. Or it can be because the powder did not ignite. Squib loads can be very dangerous in rapid-fire situations. If you EVER get a squib load STOP immediately! Do NOT fire another round! This is because the squib may have left a bullet inside the barrel.
Here’s a very cool 3D Animation showing pistol rounds being fired. Computer-generated graphics provide a look inside the cartridge at the moment of ignition as the primer fires and the flame front moves through the ignited powder. It’s really kind of mesmerizing. If you’ve every wondered just what happens inside your cartridges the moment that firing pin strikes, then watch this video…

This animated video from German ammo-maker GECO (part of the Swiss RUAG group of companies) reveals the inside of a pistol cartridge, showing jacket, lead core, case, powder and primer. Employing advanced 3D rendering and computer graphics, the video shows an X-ray view of ammo being loaded in a handgun, feeding from a magazine.
Then it really gets interesting. At 1:28 – 1:50 you’ll see the firing pin strike the primer cup, the primer’s hot jet streaming through the flash-hole, and the powder igniting. Finally you can see the bullet as it moves down the barrel and spins its way to a target. This is a very nicely-produced video. If you’ve ever wondered what happens inside a cartridge when you pull the trigger, this video shows all. They say “a picture’s worth a thousand words”… well a 3D video is even better.

According to Military Times, the U.S. Special Operations Command (SOCOM) is considering replacing the 7.62×51 NATO in semi-auto sniper rifles with a mid-size 6.5 mm cartridge. The two leading candidates are the 6.5 Creedmoor and the .260 Remington. These 6.5 cartridges would deliver a flatter trajectory, better long-range ballistics, and reduced recoil compared to the 7.62×51 NATO (aka .308 Winchester). While the .260 Rem enjoys a case capacity edge over the 6.5 Creedmoor, in the real world, performance is similar — both cartridge types can push a 130gr bullet to velocities around 2900 fps. (See Sierra 6.5 CM Load Data.)
“Major Aron Hauquitz told Military Times Tuesday that SOCOM is in the preliminary stages of exploring a sniper rifle chambered in the 6.5 mm caliber. The two commercially available rounds being evaluated are the .260 Remington and the 6.5 mm Creedmoor.
Research shows that both rounds will ‘stay supersonic longer, have less wind drift and better terminal performance than 7.62 mm ammunition’, SOCOM officials said.
‘We’re purely in the exploratory phase’. Hauquitz said. ‘We’re trying to see if we can take a weapon that is 7.62 and give it greater range, accuracy and lethality.'”
The SOCOM representative indicated that test rifles in 6.5 Creedmoor and/or .260 Remington might be issued to test teams later this year, but there was no issue date in place yet. Hauquitz said the 6.5 mm exploration came out of preliminary results of the Small Arms Ammunition Configuration study, which assesses commercially available ammunition and new ammo technologies.
SOCOM Also Considering Polymer Cartridges
The Military Times report also revealed that SOCOM is considering polymer-cased rifle ammunition, with the goal of reducing load weight. SOCOM’s research shows that a polymer-cased mid-sized 6.5 mm cartridge could be one-third lighter than conventional brass-cased 7.62×51 ammo. That means the next-generation 6.5 mm ammo could “come in at 5.56×45 mm weight ranges”. While SOCOM is seriously looking at this new option, polymer-cased ammo will NOT be required for SOCOM’s new semi-auto rifle. In other words, if the polymer ammo is not ready, that “would not delay potential fielding of a 6.5 mm rifle” according to Maj. Hauquitz.
The Savage A17 earned honors as American Hunter’s 2016 Rifle of the Year. And now this popular auto-loading 17 HMR is even better. Savage Arms has released two new “Target Sporter” versions with heavier barrels and beefier, laminated wood stocks. We particularly like the new Thumbhole version, shown below. MSRP is $631.00 but ‘street price’ will be much lower.
These new models feature 22″ button-rifled heavy barrels for improved accuracy and Boyds’ gray wood laminate stocks for improved ergonomics. As with all A17s, the new wood-stocked Target Sporter models feature a case-hardened receiver, chromed bolt with large charging handle, 10-round rotary magazine, and user-adjustable AccuTrigger.
Features & Benefits
• First reliable semi-automatic rimfire specifically designed from for 17 HMR
• Delayed-blowback action for safe, reliable cycling
• Hard chrome bolt with oversized bolt handle
• Case-hardened receiver and 22-inch button-rifled barrel
• 10-round rotary magazine
The A17 platform is the first delayed-blowback, semi-auto rimfire designed espressly for the 17 HMR cartridge. The unique delayed-blowback action allows safe, reliable semi-auto cycling with normal 17 HMR loads. We tested the original A17 and it proved accurate and reliable (so long as you made sure the magazine is completely seated). In fact, the A17 we tested flawlessly powered through multiple magazines in rapid-fire. Savage has modified the magazine well slightly to enhance reliability (see below). Now it’s easier the get the mag seated — the key to 100% reliable cycling.
How the A17 Works Using Interrupter Lug
For the A17 series of auto-loaders, Savage engineers invented a new delayed-blowback action that employs an interrupter lug to hold the bolt closed for a few milliseconds. Savage engineers scrapped the standard straight-blowback approach, which ejects spent casings via overpressure during firing. In its place, they opted for an interrupter lug that locks the bolt until peak cartridge pressure has passed. The timing system prevents the bolt from opening prematurely, effectively putting an end to ruptured cases. By doubling as a firing pin block, it also prevents out-of-battery firing with an open action.
The AR-10 was designed to handle the 7.62×51/.308 Winchester and other .308 “family” cartridges such as the .243 Win and .260 Remington. Our friend Dennis Santiago recently put together an AR-10 to shoot the accurate .260 Rem cartridge. Here is his initial report:
AR-10 Platform Chambered for .260 Remingtonby Dennis Santiago
I was very curious to see how the .260 works in the AR-10 compared to a .308. I’ve always thought about chambering a bolt gun in .260 but before doing so I thought it’d be good to try it using a less expensive entry point. With an AR platform’s easy interchanging of barrels, it seem like the best way to test out the .260 Rem chambering. So far, it’s most impressive.
DPMS LR-308 in .260 Remington getting function cycle tuned and zeroed
I took the AR-10-type .260 Rem a step closer to being ready for matches yesterday. The first order of business was to confirm which buffer spring to use with both the 123 grain and 140 grain bullet loads. My .260 Rem loads, on average, are using 4-5 grains less powder than the .308 loads. In a semi-automatic action that means less gas/energy to work the mechanics. The solution in an AR-10 platform is to either cut coils in the .308 spring or use a weaker AR-15 buffer spring; yup they are not the same. In this case, a CS flat spring for the AR-15 did the trick.
I also put a very nice NightForce Benchrest 12-42x56mm scope that came via friend Mark Gravitt on it and got zeros. This scope’s 1/8th MOA clicks are nice. The AR-10 had previously mounted a NightForce F1, a more “field tactical” 3-15X system. This 12-42X scope now sets this gun up as more of a target cannon. Field of view is limited when your minimum magnification is twelve. Maybe I’ll put an auxiliary red dot on it just to find the target.
Pet Loads: H4350 and Lapua 123gr Scenars Comment by Daily Bulletin Editor
Over a two-year period, this Editor put a lot of rounds through a .260 Remington. I did a ton of load testing with that Savage-actioned rifle (before it was rebarreled as a 6mmBR Norma). I tried two dozen load recipes with five different powders and bullets ranging from 100 grains to 142 grains. Hodgdon H4350 was my “go-to” powder. As many 260 Rem shooters have discovered, H4350 is a winner in the .260 Rem. This propellant delivered the lowest ES in my rifle and nothing beat H4350 for consistent accuracy with bullets in the 120-140 grain range. My most accurate load was with Lapua 123gr Scenars, pushed by H4350 and CCI 250 primers. The 123gr Scenars worked well jumped as well as seated into the lands. Best accuracy, in my 24″-barreled .260 Rem, was right about 2950 fps. Other powders work well, but H4350 is a very good choice for the .260 Remington (as well as the smaller 6.5×47 Lapua cartridge).
