If the 243 wasn't a dubious calibre on large deer there wouldn't be these regular threads on their effectiveness. Sure they will kill deer but so will calibres much smaller. However, if you're regularly going to be shooting stags down south I would not recommend a 243. East Anglian red hind are the same size as Scottish stags. When shooting big stags (Red and Sika) and even fallow bucks, I want them to drop close to where they were shot and often really close or they will be unrecoverable. Would a 243 be my first choice for shooting them? Absolutely not and you will not find too many others with a choice taking it either. Experience is a great teacher!
What did your experience teach you? If a large red hind isn’t dropping at or close to where it was shot with a .243, that is because it’s being shot in the wrong place and/or with the wrong type of bullet. This can be the only possible explanation, for those of us (and there are many, contrary to what you might think) that regularly shoot large red hinds with a .243 watch them either collapse on the spot or make a few yards before collapsing. Often from far longer ranges than seems to be “acceptable” in the UK. If the rifle wasn’t capable of achieving this outcome 99 times out of a 100
do you think we would persist with using something not up to the job?
I don’t buy the arguement (clearly), it suggests that most deer hit with a .243 run much further than larger calibres. That’s utter bollox. Different species, conditions, calibre, rifle makes or medium game expanding bullets - variations in these factors have made very little difference in my experience. Using a .243 Win, or a .223 Rem, .25-06, 6.5mm, various 7mm, .308 Win, bolts, semis, lever, single shots... What seperates their performance is practice, patience, understanding anatomy, understanding ballistics, bullet construction.
There’s a lot of shooters out there without much of any of these skills... snap shots at game in thick cover, or as they shape to run, or in questionable light, or from a questionable angle... all these factors add up to runners, and yet the finger gets pointed at the calibre or the bullet. And the history of whatever calibre, the years and years of proven capability written up in the annals of the sport from all over the world, is ignored.
On the 4 continents I’ve lived and hunted medium game over the years, I can break down the requirement of the rifle, load and bullet into three basic types of deer shooting that I enjoy, each requiring a different approach.
1. Open country short to medium range (say up to 350m).
2. Open country medium range (300m to say 600m).
3. Closed country wooded / scrub short range (20m to say 120m)
I haven’t gotten into the proper long range stuff. That’s a whole different ballgame.
The prevailing norms for these categories vary from place to place in the world, that’s been my experience. Where “slow and heavy” might be the norm in E Africa, it will be “light and fast” in parts of the US for game in the same weight range. What I will say is this: anyone who thinks the .243 Win is an unreliable cartridge in category 1 is either lacking in some of the aforementioned basic skills, or is simply a bad shot. The rest of what I’m thinking I already said on page 2!
