.300 blackout or something different as a handy farm rifle.

Chamber adaptors were a section 1 item until challenged by a collector. They exist off ticket now but aren’t very common!
Popular ones were .223-.22Lr and .303-7.62x39 but I’ve seen cartridge carriers using rounds like .310 cadet made in .303 for Vickers Machine Guns and they are hens teeth.
You have to remember that poi will be different but are very useful training tools

I have a couple of .410 adapters for my 12 bore's but hadn't thought of them for rifles.. not sure I'd want to risk it in a rifle though..
 
I wouldn't count on either one expanding to the degree that has any meaning, especially on light targets. There surely have been lot variations and/or R&D after initial launch, and current ones might be better.

Rather make a jig and file (or machine) a bullet of your choice to large meplat flatnose. Or if you have soft extruded bullets like H&N, Berry's etc. available, make a jig and drill a hole, about 3.5mm is fine for 30cal. I use "hollow point" (actually small dimple) H&N, but if the bullet is pointed you need to file it flat first. Beware that even if light 125gr projectile loses 2/3 of weight as shrapnel, there's still the bottom 40gr that ricochets as any 22LR...
Yip. I’d be going 223 with a 40-50 vmax fast. Suppressed. Then it “should” splash on the ground if you miss or it goes through an animal.

No one will hear a thing at night. They will all be asleep or watching tv.
 
I've been thinking about treating myself to a fresh rifle. Currently have the usual .22 lr, a 17hmr that is probably my favourite and a .243 that's big enough for any deer on my farm. Used to have a .308 but sold it as it wasn't screw cut for a moderator and didn't quite fit me plus the ground I shoot on is more 30-30 country than .308. We have lots of small fields with most shots being 70-80 yards at the most. However it did come with a nice Swarovski scope which I kept.

Which got me thinking about the .300 blk. I think it would be ok for foxes around the lambing pens with subsonics which is my main attraction as we have alot more neighbours living in barn conversions ect.. but I can't really think of much else it would be used for as they haven't enough ooomph to be deer legal though I think standard rounds would drop a close range roe. Do many folks use them in England use them for pest control?
Which brings me to part two of my post, what other calibre could I buy instead? I've already got a .243 with lots of ammo available so any suggestions could be unusual with less ammo choice availability though i don't fancy re loading. I've also half fancied a .223 or a 6.5x55 or should I get a nice short single shot .243 and have less sizes of ammo to store? Even the odd 7x57 has caught my eye but it was mostly .300 blackout I'm curious about at the moment..

Thanks in advance, Zero.
Re reading this post I can see the desire for the 300 Blackout. Pretty much a bigger and larger 22 Rimfire. The 243 does everything deer wise as required. But a little .222 or .223 in a nice light rifle - eg the little CZ or Ruger American could be a perfect rifle. Good for vermin, foxes and small deer. And 223 especially is cheap to run. 300 Blackout is quite a bit more expensive in terms of ammo.

Shulz & Larsen make a really nice little scaled to cartridge sized rifle in a switch barrel format. You could one in 223 and one in 300 Blackout.

I was leaning towards a .300 blackout when I first posted the above question however after reading everyone's posts whom I'd like to thank for taking the time to type I'm now thinking a .222 or .223 might be the way to go as their fairly common, light to carry, would drop a fox across every field I farm and the ammo is reasonably cheap compared to other calibers.
I was reading some old Gun Digests a few evenings ago as well and I've come to the conclusion the blackout just wouldn't fit on a farm. It's almost equivalent of taking a petrol car from the 60's and fitting a lumpy diesel from the 50's and expecting it to be good cos your running it on modern fuel. Maybe a bit cruel an analogy as I know alot of people enjoy their .300 blackouts but for me at least I'd be better off doing the paperwork for something different..
 
I think people also need to understand that Blackout load data is intended for semi-autos, and as such have a peak pressure of around 51k.

In a bolt gun, running decent brass (reformed LC or Lapua/NAMMO .223 brass) you can run the Blackout much warmer than you'd think.

I don't know of a cartridge that can not be loaded warmer than one may think my friend apart from 22 jet and 22 hornet, not that I haven't tried in the latter.

I've read about hotter loads in blackout but I just don't have the time to do the re loading, so my options are governed with whatever the local gun shops are in the mood to buy in. Have only found one gun shop locally that has .300 blackout in and I think thats only because their one of the few shops in the country with a blackout rifle in stock to sell..

That's understandable.

Just so you know, 300BO brass is easily made from .223 brass. You just chop the brass off with a small chop saw at 1.368", and then run in through a FL sizing die. Done. (I just made 300 pieces on Sunday, as a matter of fact.). But then again, range .223 brass is available (and free most of the time, if you ask), so it's a slightly different set of circumstances here in the US.
 
One of my local Swedish stores normaly has fmj, vmax and subsonic 300blk ammo. For rabbits and other shortrange stuff I would use H&N 125gr HP softlead plated bullets the reloads of them cost the same as 22wmr ammo.
 
Currently got my eyes on a CZ 600 Trail in 300blk soon

I use & loaded lots for 300 Blackout with all bullet weights for shorter range field use (& paper out to 600yds).
I shoot a non-standard Rem 700 Tactical & Bergara BA13 for field & love it for ease of use and amazing accuracy.
I'm sure the efficiency of the 300 Blk with the Barnes 110grn Tac-TX @ 2350fps - 2400fps might surprise you......
I've loaded subs for a variety of chores & range use. Ricochets potential problem in the field.

Remember the fact that everything ricochets , its just you are more likely hear the subsonic bullets when they do it . Many years ago i got to see a 140 grain seirra pro hunter raise a rooster tail of spray of a close cropped wet grassy field full power load from the 7-08 . There was no noise made at all ! deer bullets are designed to not break up easy and energy remaining in the bullet after the impact with the unknown is the factor that dictates if a ricochet occurs and if we hear it or never know one occurred its a case of " the silent ones are more deadly " .
 
How much punch do you need, and at what distance?

Things might have evolved, but some time ago there was somewhat consensus that you really need to step up to 45cal to have a reasonable change in terminal ballistics (people shooting pigs with subsonic rifles in US). When you step up to the 44/45cal you also have pistol bullets available in weights and construction to guarantee proper internal ballistics and reliably expand in subsonic velocities.

If you want to stay smaller, I'd look into cartridges using 35cal (and currently also 40cal) pistol bullets. If you stay inside "easy distances" (50m or so) or even stretch out to 100m, BC doesn't mean anything. Well it could mean in some cases where you're borderline legal with energy requirements that are not measured at muzzle, but nothing else. If you plink at several hundred meters the BC is important, but you don't need "punch". More affordable 30cal choices give you more triggertime, wind reading etc.
