All well and good people spending your cash upwards of £300!
My money is on you wont go to H&H
Not using your gun a lot also with it not fitting you, is the direct result of the lump you get every time.
If the barrels are not in line with your sight picture then you will push you head over to archive that, with all guns the place you rest you cheek against the stock needs to be in the right place much the same as the height of scope with all the low-medium-high rings.
I have not long fitted a drone 10 nv to my .243 and was all over the place until I packed up the stock as the unit is higher than the Kahales on medium rings I've had on there for 7 years.
It is a R/H rifle and I am L-H, My .270 is the same...
As first posted my shot guns all have had a left cast put in them. ( not H&H prices )
The stocks are all the same length and so are the barrels, the 425 is 1/2lb more as it is 3"
The only thing I don't do is go out foxing after using the shot gun all day on pigeons/ducks etc
(A) because I will be tired (B) I have tried it and snatched the trigger missing a fox.
You will see in replies on here people who only type on what they have done back in the day...
