Thread: rifle change / load/ no bumps etc

https://www.nzhuntingandshooting.co.nz/f15/dum-86976/

all the obvious causes listed in here just incase its a hidden obvious cause

Dont rule out someone being smartass and playing with scope -we had a fuckwit in camp Southern Te Urewera who thought it bloody clever to give ya scope a good wind if ya were not looking - took awhile to work out what the hell was going on - Boss gave him the talk around the road out and being not suitable - stopped

If you are sure it’s not shooter error then it has to be a zero shift.

If your thinking about blaming the powder for a change in velocity what do you reckon the worst case scenario would be?

+\- 50fps?

That wouldn’t make too much difference at 300yards. Put it in you ballistic calculator to see.

iv also had a different situation where the recticle inside the scope came loose so give things a good shake to see if anything is loose

most of the time its just loose bolts or screws

i have no idea lol hence why i have asked lol

Very strange indeed to completely miss 3 times at 300 yards, when it had all been bang on. I don't think powder temp or seating depth change would make enough difference to clean miss at just 300 yards, I think you are looking at something more physical, scope, scope mounts, action screws etc.

It'll be interesting to see what you find at the range

Any damage to the crown or suppressor? That could explain a sudden change if everything else has checked out fine.

If the story is as you say I find it hard to believe you could possibly *bump* the scope out of alignment considering the quality of scope and rifle.

It's either you aren't a very good shot or you have had a suppressor failure/strike imo.

As I say, if the story is like it's written....

Or.... you weren't happening to be spotlighting or night shooting? Very easy to assume misses at night depending on terrain. It has happened to me very recently

Over the years I have heard multiple times about a scope staying zeroed after a heavy fall, but a slight bump causing major issues.

Are the turrets tight? I'm not familiar with your scope, but the Loopy CDS ones are only attached by a few grub screws so could possibly turn the turret without actually adjusting scope - your scope could still be set for your 467m shot.

But the first question should be....are you sure you missed?

100% missed, no pop, deer ran up hill each time without any problems. Have checked the zero stop, all seems well, will check suppressor but don't think I have had any impact on it.

now here is a suggestion for you...actually for all of you.
when your rifle is sighted in...to your desired ZERO.... put the plurry colimeter/boresighter back on wiggle it around till it settled in place and WRITE DOWN where its now pointing...it doesnt matter a shit if its 3 squares left and 2 up....thats your zero.
in future if you have doubt you slip it on and have a squiz.
you can even swap scopes and retain your zero.....near enough for sub 300yrd close enough anyway...as said earlier,assuming deer had 20" chest...you missed by 10" either way at 300 yards so out by at least 3" at hundy......that will show up like pooh stain on Nanas rug.

you dont need to go to range to check scope is dialing right either...you can watch it do its thing....

Some of us don't use fancy pants super flash harry colimeter contraptions totally unnecessary gear snob kinda kit......we just shoot paper like men did back in the old days sorry MD couldn't resist

yeah but its plurry handy bit of kit to have when something like this has happened...... did you want one???I happen to have two LOL.

I'm hanging out for the result of the trip to the range
