Hi there
I got a question about a wandering zero. Typically on a 13 round shoo. 3 sighted. 10 to count. I start off fine and my poi is spot on. Around the seventh shot the poi drops radically. In the region of 4 minutes. I have already checked all nuts, bolts and washers are tight. The barrel is bedded and packed. No cracks. Clean barrel. Actually a new barrel. It seems to me that when the barrel gets hot it bends and muzzle effectively points lower.

I'm honestly not sure if that's wandering zero, or something else like a bedding issue that shows up as the barrel heats.

Its come up several times in regard to the No5 but as of yet no-one has actually defined what exactly "wandering zero" is defined as!

Should it be on Monday its fine, but on Tuesday it magically shifted. Or perhaps what you're experiencing. Or maybe even odder in that it can swap between both?

What I'd suggest you try it to repeat the 13 rounds, marking each impact by number. Now leave the barrel to cool down fully & then repeat. If its heat related the zero will jump back to cold & then creep to hot all over again. if its something else it'll continue to drift.

Out of curiosity, what ammunition are you shooting? I have 2 #5's and haven't experienced your issue at all. I shoot PPU 174 grain FMJ and Federal 150/180 grain soft point ammunition.

Methinks its the shooter, to be honest.
I have a No5..& I cant hit squat with it. I hand it to my English buddy (Collin) & its "spot - on".

He struggles with my P-H No1 MkIII* sport, but for me - its spot-on.

Maybe not, but with the No5 being a bit more lively in the recoil department, perhaps the shooter can compensate a bit for that, a wee flinch, perhaps even imperceptibly, but maybe doing it a bit more as the shots mount up. But, as I said, maybe not. You could try it using a bench rest or similar, see if you can eliminate the human error thing.

that used to do strange things.

I had a customer come by the shop asking me if I had this problem with the last batch of HXP that was on the market , since he and I had bought some... He said some one on another forum was complaining about it ....
We set up 4 targets and shot 5 strings of ammo , I shot one string he shot 3 , he had one wonderer in each of his , Mine was 4 shots that you could cover with a silver dollar and one about 3/4 of an inch to the upper right ....  My conclusion was the shooter , since we both used the same rifle ... and my shots were grouped closer than his shots !!
We were using his No4 rifle !!!
Dont know if this will help .......

I think that's a "flyer" not a wandering zero.

Try bench resting at 200 yards, 300 if you can.

Off hand, it is not unusual for me to have in a string of five shots, one good one and four flyers.

Hi
To answer some questions. I hand load 174grn FMJ at 2250fps.
I shoot Bisley competition with this rifle, and it is only recent that the poi started moving. It is not flyers.
My first 6-8 shots go in the 5 ring then suddenly start going low into the 3 ring. This not a once off and happens on every shoot. Very frustrating.
The barrel is not original, but heavier Truvelo barrel.

Does it cancel, then repeat if you let the barrel cool completely?
Does it come back in the same way at the same point in the string?

Well Saffer..it couldn't possibly point any lower than the barrel Rhino has! If there has ever been a barrel you could call a "sway-back"..this is it!!
The sad part is he paid good $$ for it.

Yep it returns back after cooling down. I have packed the barrel to ensure a snug fit. I am suspecting that the wood is warping with the barrel.
