It has to do with the low brisance of the SPP, and the (relatively) weak neck tension of the thin walled Hornet case. SRP's can sometimes dislodge the bullet before ignition has fully begun, causing erratic ignition (powder column gets inconsistent dispersion as the primer ignites the rear). This is most likely why (until Lil'gun came along), people seemed to always have problems getting extremely accurate rounds.

Thanks for that. That makes perfect sense.
This is also the reason the 22 Hornet seems to respond very positively to a light crimp. It delays (and uniforms) bullet jump, and with the heavier Lil'Gun charge weight, ensures a very repeatable dispersion of the powder column.Thanks for that. That makes perfect sense.

I always crimped hornet reloads
Ah i think you bought the none Hornet specific Sierra 45 grain ? There is a 223 and a 224 sized variant also my CZ shoots either but i prefer the 224 version
the hotter primer can move the bullet , especially if your using minimum neck tensions . Remington do an extra weak primer , its always worth a try some get better performance with it ( though i never noted any difference

Is lil gun covered by reach or is it still being sold in the UK?

I haven't had an issue
Grabbed a slack handful of 22 hornet rounds the other day, and one of the bullets fell out.
A session with the crimp die sorted them all out, not sure why I didn't crimp when I loaded them.
Lesson learned there.
Fired a zero check, single shot at 130m and absolutely spot on.
Really should do a five shot group and see how its looking.

Think I wrote somewhere that crimping hornet ammo is the best approach to achieving meaningful and consistent neck tension. Something that even with a neck bushing die is far from guaranteed due to the limited amount of bullet contact with the neck. Further impacted if your seating depth is governed by 'chasing' the lands.

That old chestnut.
Old ones are the best.That old chestnut.
I have shot a lot of 22 hornet , its my most shot caliber for near enough 15 years ? The rifle is a CZ , I bought new , i bedded it including pillars. Up front it carries an MAE Scout moderator the scout version ( shorter one ) . Cant remember if its 1-14 or 1-16 but i think its the latter . The 40 grain V-max would be ideal but its just a tad too long for the mag , seating deep is not a good option , this bullet when i remove the tip with a file works great and feeds ( its a big fuss and time hungry though ) hence i gave up to it .
RWS brass is brilliant ! That said its hard to get unless you buy their ammo and keep the brass . I mainly have used the seirra hornet .224 diameter ( they also make a 223 dia one which i have also shot ) the smaller diamiter shoots ok in mine also just not as tight . Along with many other bullets too many to recount . The only bullet i am not keen to buy is the 35 v max , it shoots well at 100 yards though is actually slower to a 200 yard target than the 40 grain std soft points available from many brands .
The 22 Hornet is a fantastic rifle for Rabbits , crows " within reach " and foxes / cubs during denning time . Its low report means you can simply sit and wait in the evening for the litter to emerge and get the lot and the vixen.
Legislation will likely whipe it out through the likes of RWS have made none toxic 22 hornet ammo but its hard to get through RUAG unless you buy a lot and its way too cooking expensive for the job over a std softpoint . The mag well size means the CZ dedicated hornet action will have to go unless someone sorts a bullet that truly fits and sells it to re-loaders . I would like to keep mine even if it meant going .17 hornet and re-barreling !

I’ve had loads of misses these last few weeks….missed seeing them because I didn’t go out!

How exactly has this been measured?
Struggling to see how the ignition of the primer can generate enough pressure to simultaneously push the bullet out of the neck AND not ignite a powder column of particularly fast burn rate powder between it and the bullet it has supposedly dislodged.
That and the fact that hornet loads are almost always filled cases or even compressed loads
Given that the cartridge tends to reach peak pressure in under or around 0.2 millisecond at which point the bullet has only moved 18mm, the lands being less than 1-2mm from the ogive on any factory load, I would postulate that any inaccuracy people may or may not be experiencing is much more likely to be every other variable.....
even Subsonic loads in centrefire cartridges with sub 20% case fill ratios don't suffer from this "issue"
It's mostly anecdotal, not measured scientifically. While your thoughts do go down the correct logic path, there clearly is something happening wrt Lil-Gun and SPP. Add to that, that Remington SRP (6 1/2's) were specifically made for Hornet and per Remington's own publicly made comments, have a lower brisance/pressure. More importantly, it is much more prominent with Lil-Gun powder, where pressure curves have been shown to be non-linear near peak pressure. The pressure slowly climbs at peak pressure, and then suddenly spikes as it crossing the threshold of a "safe" load.
There have been (literally) decades of seeing this behavior with Lil-Gun in the Hornet case.
As for QuickLoad, I'd be careful of trusting everything it says. Historically, it never lined up with what was observed in the real world. Close, yes. But never was it ever exact. Granted, I haven't used their software in a few years now (primarily because it ended up being a very expensive "educated guess" when it came to predicting pressures). <shrug> Maybe I'll buy a newer version one day (along with another copy of QuickDesign), but I just haven't found it useful enough in the past to be worth the cost (though I see now that it has come down significantly in price; it used to be $450 a copy, per each software baseline back when I used it all the time).
