What Accuracy Do You Require from Your Deer Hunting Rifle?

By accuracy in the title I’m referring to the kind of pure rifle accuracy you expect to get from your hunting rifle when shooting it off the bench with good front rest and rear support—in other words taking the human element out of it as much as possible. With all the talk and advertising surrounding 1 MOA accuracy (with this guaranteed from some rifle makers), is this the accuracy standard you require from your hunting rifles?

It might be informative to look at a typical hunting rifle scenario. When in the field shooting from typical field positions (kneeling, sitting, offhand) in usual field conditions (uneven terrain, the possibility of high grass or other obstructions, being out of breath, being excited when you see game, the need to get a shot off quickly, etc.), let's say that you are able on average to keep all your shots within a 4.0” circle at 100 yards, and this is with a rifle that gives 1.5” accuracy at 100 yards off the bench while well supported—so with what we may call a 1.5 MOA rifle. We might term this 4” at 100 yards practical field accuracy and is a combination of rifle accuracy and what we may term shooter accuracy. This level of field accuracy (4” at 100 yards) is actually pretty good in typical field conditions. So ignoring conditions like wind, you can keep your shots within a 12” circle at 300 yards with this rifle. The question arises as to whether you should seek more rifle accuracy, say a true 1 MOA rifle.

It turns out that given your shooter accuracy and under field conditions, this new 1 MOA rifle will now put your shots into a 3.84” circle at 100 yards (instead of the earlier 4” with your 1.5 MOA rifle) and will put your shots into a 11.52” circle at 300 yards (instead of the earlier 12” with your 1.5 MOA rifle). So you gain less than ½” smaller impact zone at 300 yards with the more accurate rifle. And just for fun, let’s consider a super-accurate ½ MOA rifle. What advantage do you have at 300 yards under typical field conditions? Well, it turns out that your earlier 12” circle at 300 yards with your 1.5 MOA rifle has been reduced to a 11.22” circle, so a net gain of about a ¾” smaller impact zone at 300 yards.

So the question is: will you benefit in a meaningful way with a 1 MOA or ½ MOA, rifle for deer hunting under typical field conditions? Seems to me that the answer is pretty clear. What do you think?
 
Unless you shoot your 3 round group ( not really a group, you need 10 rounds for a meaningful group! ) you should establish what your rifle will do from you likely shooting position when stalking. You can use MOA if you like, but I think a 10 cm circle at 200yards or metres from a position of your choice sorts out the shooter and the rifle!

Keeping it simple and forget the maths just whack it...To have all that going on above is just asking for trouble. :rolleyes:
TBH there are no field condition ever the same as the previous one has past just like the tide the next one is different

 
I completely go to pieces shooting at paper targets. No idea why. All the symptoms of buck fever. Can't shoot groups for toffee. If I can put 3 shots in a 3 inch target at 50 yards I'm doing well.
But on deer I'm always calm and relaxed, no shakes, and comfortable to head shoot out to 120 yards or chest shoot out to 230 yards.
I find zeroing quite challenging, but once I've got that over and done with I'm good to go.

So, my accuracy requirement is that the first shot from a cold barrel goes pretty much where I want it to go. I'm not that interested in 2nd or 3rd shots.
 
First round on a cold clean bore must be spot on with two more within 1/2-3/4 MOA group. Sako rifles do this consistently

I go over the top for brass prep and reloading and accuracy requirements, for one reason.

Respect for the animal and should it go wrong ,confidence in myself and kit should I need to take a longer shot.






Ok that’s two things
 
With PPU 90 grain in my CZ550 in .243 win, I expect a 50mm group from 150 metres.
Thats with a bipod. There is obviously some degree of wobblyness involved in my participation so the rifle/ammo combo is capable of better than that.

I seem to remember you giving advice on here before that you don’t need to clean a rifles barrel, and that your rifles are perfectly accurate doing so.. I think we have come to the conclusion of how some people get away shooting minging old rifles that have never been looked after, they just have a very different idea of what acceptable accuracy is!

You may well be right!
Acceptable accuracy to me is that the deer I'm shooting at drops down dead with a hole in it that corresponds to the part of its body I was aiming at.
Seems to work. Consistently.
