Have you fired a round with a bullet already part way up the barrel from the previous shot? I came close to doing this a couple of years back but the report didn't sound right so took a squint up the barrel (after unloading of course)Has any other member had issues with a partial discharge in this calibre causing damage to your gun or injury.
I have had maybe 3-5% of Hornady cases split. And the distribution is random: i.e. it is not as though one batch does it, rather some cases in every batch.[Same rifle for years] But splitting does not seem to affect accuracy. I have had relatively few fliers in hundreds of rounds and none of those cases had split. Mostly happy with Hornady .17hmr.Have had a few split cases here and there.
£13.50 a box. Crikey, my local is £21 a box. Like you say, cracking high volume night time round for rabbits. At the price of HMR, it is all I use mine for now but for that purpose, it is peerless.I had a CZ452 with a squib round jam in the barrel which I didn't realise at the time, fired another one down and the stock blew up in my hands scattered all over... Edgar brothers replaced the stock and some of the trigger guard area, said the barrel was undamaged.
This was using the old Hornady blue tips which they recalled... I've not had an issue since, just the occasional no fire from winchester ammunition ... the new hornady and federal are spot on. I love this round, its very flat shooting for NV/Thermal vermin control out to 150yds and requires minimal reticule holdover out to 200yds, I did try going down the .22 hornet route but its a pain in the arse reloading in any sort of number when your going through 50-100 a night... local store stocks hornady at £13.50 a box so its so much easier than all the reloading in this case for me...
