Thanks for all the interesting and helpful comments. I now know more about the use of shotguns on deer. I can't see myself using a shotgun as my primary big game weapon, but it is good to know what to expect if I do.
Good stuff Erasmus. As I was growing up, the main three firearm types my buddies and I were aware of were .22s, shotguns, or .303s. As a gun club member, I recall being able to purchase a nice, well-preserved in grease No. 4 Lee Enfield for about NZ$11.
My dad had a few different Lee-Enfields, but the first one I really called my own was an old altered "Long Tom" that had been fitted with another barrel... possibly a Lithgow target barrel. The date on the side was either 1896 0r 1898. I can't recall for sure which one. My dad sold it to a buddy unfortunately, so I ended up just using other guns we had hanging around. It was a pity he got rid of it because it was a solid weapon and it would have been nice to have been hunting with a gun that was 110 years old.
We used to do target shooting with the Lee-Enfields. With open sights we would sometimes out-shoot guys using newer guns with scopes. Most of the shooting would have been done at 200 yards, and the 'bull' was maybe six or eight inches in diameter. I've seen some very good grouping at this range. A lot of the time we just used the standard aperture sights that came on the No 4s, but some guys would have fancy adjustable eye-pieces at the rear sight.
The ammo we used was the MK vii military stuff. Cordite filled, solid bullet. It wasn't an ideal game round, but heck it was accurate. We had a lot of it dated 1957, and I think there is still a bit of it kicking around. Of course it had the Berdan primer with the double flash hole, so it wasn't simple to reload. We did play around with loading it though. We cast quite a few projectiles. I also have a jar full of cartridges that we fitted new projectiles to. We pulled the military heads, then fitted some nice round-nosed ones that weighed maybe 210 grains. Fortunately, before we shot too many of them, my uncle did some research and realized that the cartridges were now dangerously overloaded. So maybe 35 years later I'm still waiting to borrow a bullet puller so I can put a safer/lighter projectile back into the cases.
Back in the late eighties, I think, my dad got hold of some 7.62 x 39 ammo - military steel cased stuff. A friend discovered that it was a cheap option for .303 shooting to pull the heads of these 7.62s and fit them to .303 British cartridges.... and then drill the points. But I wasn't using a big gun much back then, and I think I only ever shot one feral goat with one of these loads. It certainly did the job.
Having all this 7.62 x 39 made us want to own something we could shoot it in other than an AK47 or SKS (which are harder to own nowadays anyway). So my dad shortened up the chamber end of a couple of .303 barrels and re-chambered them for the new cartridge. He had to fiddle around with the magazine quite a bit to get it to work, but we have ended up with a couple of Lee Enfields that now shoot the more readily available cartridge. My dad passed away some years ago... but between him and my brothers we have taken a few animals with these special rifles. One has a scope and one is a beautiful short rifle with old military vee sights... they look like the old Martini or maybe early Long Tom sights to me, but I'm not an expert. But I do know that I like this rifle. I was very pleased with one shot I did with it. I'd been trying to get a deer for several days. On the last day available for hunting I saw some deer. By the time I got to a shooting position they'd climbed further up the ridge from me until they were maybe 110 to possibly 200 yards away. I know this estimate is vague, but it was across some hollow ground. I do know that the deer looked fairly small over my sights. I held my sight at the very top of the deer above the front shoulder and pulled the trigger. The deer gave a leap, took a few steps then fell. I'd shot it right through the heart. But it still took me maybe an hour to find it as I couldn't keep my eye on the spot where it had fallen as I had to cross a hollow.
I feel a twinge of nostalgia when the subject of Lee Enfields comes up. However I think if I get another centrefire it will probably be either a .223 or a 7.62 x 39 fitted with a moderator.
My brother still has a number of Lee Enfields... and a whole stack of parts etc. He is quite an enthusiast and Lee-Enfield historian.
I still think that if I had to pick just one gun to depend on, it would be a Lee Enfield shooting military ammo. I am just so familiar with them, and they always have been very reliable for me.
Great topic. Thanks.
