Time for some of us to give up on the 17HMR???



Log in to see fewer ads
As everyone knows, many members are really struggling to find ammo that fires let alone get the groups we got 10 years ago.

I have two Marlin 917's and out of the last 3 boxes of ammo:
Winchester 5-10 out of 50 went off the first time
CCI 10 out of 50 went off the first time
Hornady 40 out of 50 went off the first time but shot 1 1/2" at 50 yards

Serious question: What's a guy to do?

No one will buy the used rifles when you tell them the truth. Your only option is to sell it to a pawn shop or Cabelas and you would probably be lucky to get $75-100 for a Marlin 917 considering you can get a new XT out the door for $250

For that little money, is it just time to put the rifles up and see what ammo is like in 5 years? Or do you cut your loses, fund other projects, and buy again should this get fixed in the future?

Just curious what everyone who has been having problems thinks

I've had less than 15 ignition issues in 6k+ rounds through my Savage and the new RAR Target hasn't had any ignition issues......yet. Ammo accuracy the last five years in Minute of Squirrel terms has been very good from 100-200 yds for me.

Old firing pin/spring issue? Could a weak strike cause weak ignition and lead to the accuracy variables?

In my last 500 or so rounds of Hornady 20gr XTP, out of my CZ 482 Varmint, I have had zero ignition problems and groups are in the .2-.3 range @ 50 yds. Maybe I have just been lucky but I love shooting mine.

Curtis - sorry to hear you are having that much difficulty with your 17 MHR ammo.

One of the downsides to having "several" rimfires is not getting around to shooting "all" of them on a regular basis. Admittadly I have not shot my 17 MHR's since last summer (both are CZ 45x - bolt actions) but I do not recall having "any" issues with ammo. Looking at the inventory I have CCI, Federal, & Hornady ammo in both 17 & 20 gr. I know that some of my Hornady ammo is nearly 10 years old, but the Federal and CCI are fairly recent.

I will say that I dumped all my Winchester 22 LR ammo acquired over the past 5 years as I was having a lot of misfires with several different types. I only kept a very old brick of T22 for plinking as it at least will go bang.

I've had accuracy issues and fail to fires, but not at that level.
I'd be checking my bolt for gsr build up and a weak striking firing pin.
Gsr inside the bolt will bind the pin and prevent a clean strike.
Did you rotate the round 90 degrees and try again?
Did you pull it apart to verify lack of primer or powder?

One rifle is new to me (looks almost brand new) and I haven't had the chance to really get it working b/c of the ammo experience. I would say there would be a defect in the new rifle if my old trustworthy rifle didn't do the exact same thing. My older rifle probably has less than 500 rounds shot through it over the years because it is just a winter time tree squirrel rifle, but prior to the recent ammo experiences I could count the number of duds on one hand and accuracy with Hornady V max at 100 yards were normally .5-.75" on a good calm day. I had to discard my old stock because they were aging and splitting cases badly.

Both rifles are putting good hard hits on the case, there is no reason why it shouldn't be going off. Obviously something is wrong though - i have not pulled the bullets out. Almost all rounds will go off by cocking the bolt and firing again - not really a viable option though. I know they have altered the brass to help keep it from splitting. I can't help but think that has something to do with it.

It's interesting the you're having issues with three brands.

It's somewhat odd that Winchester isn't the worst by a larger margin.

The constant is the manufacturer is Marlin.

What conditions has the ammo been stored in? High heat, freezing. excessive moisture?

Have you noted the lots and contacted the manufacturers to see if they might be suspect?

If they are going off on a second re-cock, could you be doing something on the first one to create the condition?

Just like in trouble shooting cars you need to wipe the slate (mind) clean and start with air, fuel, spark simplistic mindset.

2 of the boxes of ammo has been stored in the basement for 2 months and the other box was bought at the store the same day. I have not called the ammo manufacturers as I have seen enough posts on the subject lately that I expected it to happen - I figured it was a waste of time. All but the hornady box has already been discarded.

As to me creating the condition, I don't know what I could be doing. I loaded the magazines just as I have for 10 years of shooting the 17hmr and 30 years of shooting 22lr.

Thank you for all your responses thus far

With that small a sample of ammunition and no idea of the age of inventory I'd get the lot numbers off the box and contact the manufacturers and hope they are honest. Usually they are due to legal issues. Hornady bought a friend a new Ruger 77/17 due to issues with the lot number he was firing after the gun blew the side out of the stock and disintegrated the magazine. I'm guessing they thought that was cheap compared to the worse case scenario.

Most 17 HMR's shoot exceptionally good but there's always variables, ammunition would be the first (and cheapest) I would rule out.

I've never had a failure to fire with my Marlin 917. Not one, using both old and new ammo from Winchester, Remington, Federal, CCI and Hornady. I'd be looking at the rifle.

Dennis.

ITs most likely a precursor of what should be expected with that new super magnum rimfire round.


Ammunition that cant last for long periods without turning into shrapnel isn't going to help sell guns. Ammunition that works after 50 years in storage helps sell the caliber itself.

For what it's worth. In troubleshooting this problem one thing that may be affecting the ignition is ... Rimfire cartridges need to be struck sharply. If you were to squeeze the firing pin onto the case just as deeply but slowly, the primer is much less likely to ignite. Could it be that fouling in the bolt is causing the firing pin to descend more slowly but with just as deep of a dent? ...just an idea.

The main issue here is your rifle from what I read , Iíve fired over 50,000 rounds for HMR since the round came out through many rifles mainly Coopers and Anschutz and Savages and maybe had a dozen that didnt fired ! I take that bolt apart and replace the spring to start with and if that didnt cure it replace the firing pin.

I don't own a 17hmr but if I were experiencing the problems you are I would first look at the rifle. If I had a friend with the same caliber I would ask him to try the ammo in question. Lets reverse the situation. Say you had one ammo and four rifles and the ammo would not shoot in any of the rifles. Pretty sure you wouldn't blame the rifles.

new firing pin and springs?

Going to go with a rifle issue, did a week in Oregon chasing sage rats. Full two bricks of federal premium, and another misc combo of hornady and cci. One ftf, out of all of them it went on the second go round. Not bad for 1500 rounds of bulk produced ammo under 10$ a box.

Seems to me its either a firing pin spring and pin issue, or a headspace issue causing light strikes.
