Bullet drop work around

[ElvisThePelvis]

I'm not sure this will work but it's worth a go... a family friend has a small holding that backs onto a permission I have. The friend has new lambs which have attracted foxes, they want foxes removed.

 

I have an HMR which is suitable at this close range, i.e. 75m. The rifle is zeroed perfectly for 17gr Hornady vmax at 100M. I have cci game point as advised by shop but I won't have time to zero before hearing out tomorrow night after fox.

 

Is there a way to decide on hold over? Or should I find a way to get away from work early and rezero?

[Vince Green]

One shot is all you need . shoot and re-evaluate hold over/under if you have to, 75m to 100m with a HMR is FA. but you should have all this sussed its called knowing what you are doing

i guess the logic to the game point is they should punch through bone before expanding.if i was in your shoes sub 100 yard neck shots with the v max would be my choice.or get time to send a good group as you might find the group opens up and one shot won't determine zero.

The point is that I know where 17gr groups, IF there is a work around how much hold over should be allowed for 20gr, no need to be a ***** about it..

Thanks Mike, so 17gr ballistic tips at that distance are ok for neck shots? Shop suggested I needed 20gr but that suits them.. I have complete confidence in shot placement but don't wish to risk wounding.

If I remember right, the difference at those ranges is next to nothing.

 

I found the gamepoints just whipped straight through rabbits and they barely flinched so I'd be cautious about using them, never tried on anything else - only one way to find out really though unfortunately. Vmax as second in mag?

As has already been said just stick to your normal ammo as at that range they will do the job spot on if shot placement is right.

[welshwarrior]

You need to check zero you can't guess then shoot a living creature. Shoot a check group and see where the bullets are going.

I had some cci gamepoints and they wouldn't cycle in the magazine. Found that without the polymer tip they got caught on the entry to the chamber and wouldn't feed in. That's in an Anshutz and using the standard and 8 shot mag.

Just use the normal 17gr rounds, had a few foxes at that range, not keen on much further tho.

Why neck shots

[wymberley]

Why neck shots

Don't know. At the range mentioned one between the eyes should be eminently achievable, not to mention the engine room. With the figures given, the bullet would strike less than 1/2" high.

[7daysinaweek]

if you know your poa with the 17gr and zeroed stick with that at them ranges. as ww says would not consider gestimating, when i use the air rifle for rabbit or my 243 for stalking and others inbetween i am confident as i can be to give humane dispatch.

[zx10mike]

Why neck shots

 

the hmr expands fast and yes it would do head shots etc but in the neck the hmr would hit some very important parts where a fast expanding round will do the job despite its low energy/weight.hey shoot where you feel comfortable it was more a suggestion of where i would shoot.

neck shots or where the individual thinks the will do the job.i'm not a fan on hmr on fox but they will do the job.they are desighned to expand fast so punching through ribs would not be my choice of shot.yes head shots work but can easily go wrong.if a fox suddenly looks the other way just as you send the neck often stays within the shot

Thanks guys, will stick to 17gr ballistic, I'm hoping that in reality it won't be much further than 50M

Thanks for heads up, this makes sense. I was cautious with gamepoint but sold to me as good for rabbit in a wind as less windy than 17gr.. maybe that's not true?

3 grains aint going to do much in the wind lol and i wager the difference in bc cuts any change (if any) by half.and chances are they won't shoot as accurate wich will wipe out any wind benefit .when you get chance let me know how each bullet groups.

I'm going to run a few through Thurs AM and will report back, I'm a little concerned the 20gr game point will just go straight through rabbits so will keep these to one side..

 

I have noticed that the Hornady group much better than Winchester both in 17gr vmax

[wymberley]

Although the energy is very close, the 17 wins on all counts regarding energy, path, velocity (obviously) and drift.

[ElvisThePelvis]

Thanks guys, two foxes removed, both neck shot with vmax at around 40 M which they knew nothing about. Results of gamepoint testing to follow in the next couple of days.

[Vince Green]

The point is that I know where 17gr groups, IF there is a work around how much hold over should be allowed for 20gr, no need to be a ***** about it..

No, I'm not being a ***! Listen to what you are being told. Fire one shot at the range you expect the fox will be and see if it goes over/under where you aimed. That's your hold off at that range.

and if that particular bullet shoots 2" groups because the rifle don't like them how do you know weather that bullet is high low furthest left or right ? surely you kneed to centralise the group ?i guess its weather your the kind of guy that says thats close enough or the kind of guy that wants precision.

Take a look at the below site.

Brilliant, thank you, will now be zeroing at 125 yards!

If the rifle shoots a 2" group at 75yds it will still kill the fox. The job was to kill the fox
