How did you come to that conclusion?From what I am reading on this thread, it looks like .17HMR is the new 6.5 mm Creedmoor!
Not one of us ever mentioned shell suit!

I very nearly did and still would as it seems ideal an HMR ++ it's a real shame CZ or tikka didn't take it on as I think it would be ideal for a lot of my shooting where the hmr is a bit weak and the 223 a bit much . Obviously I am aware of the other alternatives . Shame it looks to be dead in the water in the UKIt's very similar to 65CM except it's like 65CM sprinkled with Holy Water.
However, if you prefer the dark side and want a 17 rimfire that's charmed with voodoo mojo magic that turns fox's lights off at 125m+ then it's 17WSM.
My advice, use both.
Ammo can be difficult to find but I have a year+ of stock. My Savage with Wildcat Whisper is quieter than the HMR. I find it's the same flat trajectory out to 140m. I wish Ruger made an RPR in WSM.I very nearly did and still would as it seems ideal an HMR ++ it's a real shame CZ or tikka didn't take it on as I think it would be ideal for a lot of my shooting where the hmr is a bit weak and the 223 a bit much .

If the lead ban is as problematic for 22lr as is suspected it would be a good 141 rimfire option .
Lucky for me the ntx 15.5 is excellent out of my tikka. Opens up after 120 and doesn't like the wind but otherwise I was pleasantly surprised...except that the non lead offering for the 17HMR groups like a 16th century blunderbuss. I.e. the V-Max that works in 17HMR is lead core.
Removed the split ones and the rest are fine



Good testing thanks.Urgh. On a recent rabbit evening I had 5 solid hits followed by three huge misses.
I went back to the range a week later to re-check zero of the Hornady V-max and sure enough, same thing: two shots in the right spot, one slightly wayward and then 4" drop from first POI on next 3.
I then shot 10 rounds of Winchester at a fresh target and it grouped OK [1.5" @ 100m]. Not as good as the Hornady usually does, but 100% better than the Hornady on this day's testing. So I visually inspected cases of unfired ammo and found some splits. By selectively chambering the obviously split cases, I could see they were uniformly striking low by 4". But some rounds that looked ok just did not group either. Inspecting the balance of the open box of as yet unfired Hornady cartridges at the range I found 20% had splits!
As soon as I got home, I then checked three other boxes of Hornady V-Max bought at the same time: split case ratio per box was lower than seen at the range but present in all boxes with same batch number: B05X18.
I found one box to be of another batch number: K28X22. There were ZERO split cases in this box. History: I bought 1000 HMR in one purchase from the same RFD a few months back. Clearly it was purely by chance that I have been working through boxes with no defects for the last few months and have only just reached the duff batch.
Having removed all split cases from sample boxes, I will now re-test some of the remaining ammo in the B05X18 batch. If grouping remains poor, then invisible case defects are potentially in play and batch will need to be replaced.

the group on a whole in my two rifles is still small enough to be useful.

Nice. I'm 204ing this evening. The first 70m rabbit just got knocked back to last Tuesday. The round is flat, fast and makes an average Joe like me look good. All for the 222 but don't overlook the 204.It's still good.
Apart from getting soaked I had 8 rabbits this afternoon.
The first 5 were for 5 shots, I missed #6 by just going over his noggin at 50ydsand then #7 I missed at 100yds
but #8 at the same spot came in for two shots
.
Basically I was doing well and then it all went pear shaped for the last two!
So 8 rabbits for 11 shots.View attachment 317906

In the past I've loaded small CF calibre rifles with cheap fmj bullets for rabbits.On the same day I proved the hmr ammo problem, I tested my latest .223 load: that is clover-leafing at 100m. A bit expensive to reload for rabbits...but it could be a stop gap solution.

It doesn't matter that the case has split after firing ,the problem is when they are split prior to firing. The splits allow dampness into the case and you then can get a squib round. I don't think the problem will ever be eradicated completely because the round is being necked down a considerable amount and the brass is very thin.I bought a second hand CZ 455 in 17HMR a few years ago. A look in my spent cases box revealed about 1 in 10 split along the case neck. Then I bought a new barrel and since then the number has dropped to around 1 in 25 or 30. I've therefore concluded that the problem has more to do with the machining of the chamber than problems with ammo manufacture, although its probably a bit of both.
