Dekers Posted April 10, 2016 Report Share Posted April 10, 2016 (edited) Hi Everyone, I thought HM2 owners were beaming joyful people with nothing but praise for their amazing rifles/calibre. mick miller has suggested on the .17 Hornet thread they are experiencing horrendous problems with Mach2, taking the form of exploding rounds! Can someone please elaborate on these issues? Thanks Edited April 10, 2016 by Dekers Quote Link to comment Share on other sites More sharing options...
tweedledee Posted April 10, 2016 Report Share Posted April 10, 2016 Right I've had my mach 2 for about four or five years. No issues until recently when I bought some rounds.turns out they were made in 2004/5 and pretty inconsistent. Have been in touch with Edgar brothers about having them replaced. I like the calibre and I argue it has its place. I also have hmr and the 17 hornet.never had any issues before now so it's lookin like somehow I got some really old stock.

That's interesting, and I'm not really following the old stock line, I have some 1985 Radway Green 7.62 and it is superb! Is it storage, or is there something I'm missing on age?

tweedledee Posted April 10, 2016 Report Share Posted April 10, 2016 Can't say mate.god knows where it's been all that time.it's ok for plinking at 50ms but not great at 100. I have fresher stuff and it's fine.I keep it stored in locked cabinet in the hotpress. It's the first time I had any issues .I know you aren't a fan and see it as a failure. I'd have it ten times over normal 22 calibre any day of the week.just my opinion Quote Link to comment Share on other sites More sharing options...

Can someone please elaborate on these issues? Thanks yes I can Out of 50 at least half the cases are split lose heads I have had no end of them squib and get stuck in the barrel Hang fires are not nice. Worst one I had the back of the case blew of and that really was a **** attack But when the good ones go off its really spot on Quote Link to comment Share on other sites More sharing options...

hyflier Posted April 10, 2016 Report Share Posted April 10, 2016 Dekers, you're a buggeroo I suspect you knew something weren't right, I've quietly been following your threads and comments about HMR ammunition. I can't say i disagree with you either as an owner of a .17 HMR, and I am convinced it has something to do with the necking down of the case rather than any quality control. How to cure it is beyond me, but this little calibre has generally been brilliant for me, firing laser guided Bunny seeking missiles for some time now. Sadly she will be up for sale shortly as my Farmer no longer needs my help Quote Link to comment Share on other sites More sharing options...
tweedledee Posted April 11, 2016 Report Share Posted April 11, 2016 I wouldn't give either mach 2 or hmr up. My ammo has been fine until the last batch and god knows where it has been stored. Quote Link to comment Share on other sites More sharing options...
Verminator 66 Posted April 11, 2016 Report Share Posted April 11, 2016 I have has a good few stuck in the barrel with my hmr as well And last week 1st time ever in my 22lr But as they say got to be the way the rounds are made Quote Link to comment Share on other sites More sharing options...
Dekers Posted April 11, 2016 Author Report Share Posted April 11, 2016 (edited) It's just too much risk to adopt a calibre with such incredibly limited ammunition supply. It's the only calibre I had that madr HMR look good in the bad times. When itbwas first launched ten years ago HMR ammo was itself in a different league of accuracy ability and that soon dissapeared but had since begun to return. Obviously individuals will experience different situations, but I have never had any accuracy problems with my HMR, neither does it take me the 50 odd shots many seem to suggest to get it straight again after cleaning, first, or at worst second shot its spot on, but cleaning that tiny bore PROPERLY is a laborious time consuming delicate operation! Anyway, I really was not aware of all these apparent issues with HM2 ammo, and as there is only one manufacturer of the stuff now I guess we know who to blame. I take it neck splits are not such an issue with HM2 though, less pressure I suspect, or am I wrong there?

How to cure it is beyond me, but this little calibre has generally been brilliant for me, firing laser guided Bunny seeking missiles for some time now. Sadly she will be up for sale shortly as my Farmer no longer needs my help Make of this what you will, via Shooting UK............ Sporting Gun August 28, 2007 Bob Palmer at Hornady, in an e-mailed reply to George’s enquiry:CCI makes the cases for all the .17 HMR ammo and loads it for the different companies. When they make the cases they draw the case out to a .22mag case that has a straight wall. Then the priming compound is put in the rim of the case. The case is spun to put the primer evenly in the rim. After the priming is complete the case mouth is reduced to the .17 calibre to hold the bullet. The reduction process, however, puts stress on the neck of the case. They obviously cannot anneal the neck of the case to relieve the stress because of the compound in the rim, so from time to time you will get a case that cracks. Some batches may produce more splits than others. The chamber pressure on .17 ammo is so low that it does not hurt the chamber on the rifle. They have tried to anneal the cases more before it’s formed to .17, but this did not eliminate the cracks altogether. If the cracks were minor I would continue to use the ammo. The cracks do not affect the accuracy of the round and the brass is not reloadable. Quote Link to comment Share on other sites More sharing options...

Verminator 66 Posted April 11, 2016 Report Share Posted April 11, 2016 this is the one that blew its rim off and no there wasn't one up the spout already Quote Link to comment Share on other sites More sharing options...

Verminator 66 Posted April 11, 2016 Report Share Posted April 11, 2016 The gutting part of it is it will clover leaf at 75yards I have tested it with the cases split and not I got 10 none splits and shot them all in an 1" got 10 with neck splits and still 1" group then a mix of 5 splits and 5 none and all still sub 1" that is the good thing so it doesn't make a difference but when ones squibs its not good at all i have even made up some blank round just so when one dose get stuck up the spout its not the end of the night for me put one of these in and blow it out so can crack on Quote Link to comment Share on other sites More sharing options...
Verminator 66 Posted April 11, 2016 Report Share Posted April 11, 2016 thats whats making me think whats the best way to store it as i have mine in the ammo safe with them damp bags in with them Quote Link to comment Share on other sites More sharing options...
mick miller Posted April 11, 2016 Report Share Posted April 11, 2016 Replace the damp bags with dry bags. The damp won't help. Quote Link to comment Share on other sites More sharing options...
wymberley Posted April 11, 2016 Report Share Posted April 11, 2016 Not some dealers's damp storage cellar Hopefully, not with the binoculars. "Yes go to a gunshop, look through a few and then BUY THEM from the gunshop, not amazon! Otherwise eventually you will all be complaining when you have a 200 mile round trip to buy ammo from the only gunshops left sadly." Quote Link to comment Share on other sites More sharing options...

hyflier Posted April 12, 2016 Report Share Posted April 12, 2016 this is the one that blew its rim off and no there wasn't one up the spout already I've only seen this once before with .22rf. There was nothing up the barrel, we put it down to the age of the ammo, some kindly soul had brought it to the rifle club where I used to shoot. I recall, there was a strange noise and a stinging burn across my wrist. Quote Link to comment Share on other sites More sharing options...

Bewsher500 Posted April 17, 2016 Report Share Posted April 17, 2016 well ammo quality is an issue but one frankly I have not seen in either hmr or m2 never heard of rims exploding until now. I have 5 rimfires and short of a few split necks and soft strikes have escaped these issues I buy a lot more M2 usually in 1000 bricks Hannams had it in last time I spoke to them so any RFD not willing to get it in for you should probably not get any more of your money....
