gun not liking ammo or am i flinching?

[nova_scotian_guy]

1980s puma 44 mag
180 grains pmu(think its the name) ammo
distance 50yards
issue ...... all the shots are either hitting high or high and to the right

.... i was shooting some 240 grain wc and swc hand loads that were over 12 years old and was hitting a 3-4 inch group open sights same distance (some sideways but all in the same group...

i have tried to adjust the sight but nothing ... so i want to know is it me or the gun/ammo combo???

randomly insert 2-3 dummy rounds into your clip of 10 and fire normally. When you hit a dummy round, you will notice whether you are flinching or not.

Better yet, go with a buddy. Have him ####/load the gun, and you shoot it. You truly won't know if its loaded or not, plus he can watch your form.

If your bullets are going through the paper sideways then you have a stability problem... either the rifling twist is too slow or the bore is oversize/bullets undersize.

possibly due to soft cast lead not gas checked and over 12 year old... wasn't to worried about the 2 out of 35 at the time (loads that were made for my fathers 44 mag colt when he had it (he did not load them someone else did)

ok i had a person i was with randomly insert 3 rounds as i was fireing that did not notice any flinching with the 180grains but i am still shooting high and to the right ...had some new 240 grains fired them and gun is accurate ...so i guess the gun either hates 180 grains or hates the pmu loads

Are you holding the rifle dead on vertical?
Canting to or fro will cause the point of impact to change........usually.

i am yes... tested another theory today ... i got someone to put 6 shells in the gun 3 240s and 3 180s at 50 yards i was getting 2 3 inch groups one dead on target and the other 6 inches high and 6 inches to the right

240 grain was the standard back in the 70's and 80's, so the rifle's twist is most likely fast for the heavier bullets.

A short light rifle with a substantial "drop" in the stock measurements and powerful loads like the .44 magnum will react significantly to the recoil of the cartridge. If the rifle was set up for standard 240 grain loads, it's not surprising that it will not shoot to the same point of impact with 180's. The dynamics of barrel harmonics and recoil "lift" are very different with a fast, light load compared to a standard load.

I find the same situation as yours with my Rossi 92 in .357/38special. With light .38's I have to adjust the Lyman receiver sight 10 calibrations vertically to hit the same POI at 50 yds as compared to .357 magnum loads.

Sounds like the rifle prefers 240s. Problem solved.

My bill will be in the mail.
