100 yards or metres zero ?

Just looked at a drop chart, a 308 with 150gr would drop under 0.1" from 100yds to 100m and a 30-30 170gr would drop around 0.3".
So, even with a "loopy" 308 most scopes would not be able to adjust the difference.

Asking as have shooting test for DSC1 next Sunday and have zeroed at 100yards and believe the test in in meters ?
You’re good to go, just have a few practice shots. For my test I set up an “on the nuts zero “ while I’d normally be about 5cms high at 100 whatever’s.
Best of luck with the test.
 
Agreed but the deer target on the test is going to "pop out " at exactly 100m 😁 just trying to cover all the bases
I feel you are overthinking it. Just shoot as you normally do, 3 shots in a 4" circle (or is that 100mm now :rofl:)at 100m. Then on the roe target, 2 shots a 100 prone, 2 shots at 70 kneeling/sitting and finally 2 shots at 40. Don't overthink shot placement on the roe, as Sikamalc says, up the front leg and put them in the middle.

It will make no difference in the DSC1 shooting test whether you are zeroed at either 100m or yards. When I did it 3 years ago I borrowed a .243 zeroed at around 100m or yards and all shots were within a 2" group in the kill zone. I didn't own centrefire calibres at the time but had practised with my .22RF rifles prone, sitting, kneeling and off sticks. In this case it definitely is the shooter that counts.
 
I’m pretty sure I did mine with 100yd zero. As above, it will be grand.

I still use yds although May abandon for a metric system on principal if I ever get a scope with turrets.

MOA works well for quick mental arithmetic 1 MOA being approx 1 inch at 100, 2 inch at 200, 3 at 300. If I’m on the hill now though I just have a piece of paper sellotaped on the stock with the drops and holdover. Much easier than pfaffing with caps of turrets etc.

The max point blank is a good system but you don’t want to be nearly two inches high at your assessment distance.... that’s only just inside a 4 inch target and leaves little room for any wobble.

Good luck with the test. Lots of excuses offered by people who did plenty of talking it up before hand but couldn’t make the standard. With any practice at all and particularly with non prone positions, you should be grand.
 
Too much overthinking leading to unnecessary worrying. :rolleyes:
The difference between point of impact for a shot fired at a target from 100 yards as opposed to 100 Metres is absolutely negligible.

Is the baby doing the shooting or do you have Covid, so how does that come into the equation?
Operate of the KISS principle, enjoy it and stop finding things to worry about. :thumb:
 
100 metres is the DMQ test distance also used by FC, so simplest to use.

In the field you can't judge range that accuacly without a range finder.

The main difference is probably confidence.
 
it's the grouping they will be more interested in, if the shots are an inch high or low it will be fine
No, the test is not for grouping.

It is pass or fail purely depending whether your bullets strike the "kill zone". They are either in, or out. Only six shots in the test now. Two at 100m prone or simulated highseat , two at 70m standing, kneeling or sitting, sticks allowed, two at between 10 and 20m sticks allowed.

I'd suggest that the new test is easier, provided you turn up prepared, with your rifle suitably zeroed and recently checked using familiar ammo..

Under the new test there is no opportunity to check zero and adjust the sights. That may be available as a separate exercise by the course provider, but no longer forms the first part of the test.

In the new test, the target now includes a second target zone on the head for a test of a freehand despatching shot at closer range, between ten and twenty yards. That I suspect might catch out even some experienced shots.

I think the target area is the same as for the chest, ISTR a 3" circle. With your rifle zeroed for a usual stalking distance, with a large objective 'scope mounted above the bore, might shoot rather differently than to a 100m zero. E.g. a quick look at some .243 ballistics suggests that one zeroed for 100 yards might shoot 1.5" low at 10 yards, scope height unspecified.

If so, and you aimed dead centre of the target, you might only just clip the edge. Or not.

Maybe worth trying this before the test

You now only get two tries at it. If you fail the second attempt you have to return another day to re-sit.

It is now shot at 100 metres, which is 109.4 yards. Nearly ten percent further away. This in itself reduces the area of the target zone somewhat, it's approximately 20 percent smaller than before.
 
if you’ve zeroed your rifle at a hundred yds stick with it, before your DSC get out and shoot 100 yds and 100 metres and shoot 75 50 and 25 just to get used to the ranges and most importantly be used to and comfortable with your rifles performance

if you and the rifle are on the ball - you’ll think its a doddle - try not to get tooooooo confused on range, check all the ranges out so you have it logged in your head and leave it at that, the rifle wont let you down
be calm and think straight

the colley wobbles will come if you let em in, ive had my more than a fair share of em in the past and probably a few more to come :doh:

good luck

perhaps I worded my post wrongly. Yes the shots must be in the strike zone but the point being that 9 yards further is not going to make any material difference
 
Regularly shooting anything with a new baby and covid going on would be an achievment 😂
I I’ve been there! Though the 2 didn’t coincide for me.

my point being the difference between POI hitting a target at 100 metres with a rifle zeroed at 100 yards is going to be something like 1/4 of an inch. Unless you can shoot inside that there is literally no point in re-zeroing your rifle. Save the ammo or better still just use it to practice groups. You could even put the target at 100 metres to see how little difference it makes

10% smaller, a 1 moa target is 1” at 100 or 2” at 200. 100% bigger at 100% extra distance.

The new despatch test sounds interesting, 10 yards with a fixed 8x56 people are probably better off looking down the side of the barrel
