So i just had a fit of " enough with the computer " so as i picked up my new heavy barrel today i figured why not clean it ( it already was )
And then run a few slugs thru it.
The barrel seem to have a long run in where i have to " really push" on the rod to move the slug forward, but after 50 - 55 mm that just stop and the weight of the 3 mm CF rod i use are almost enough to push the slug the rest of the way thru the barrel, at least very little pressure are needed for the middle part of the barrel.
When i then reach the muzzle end the barrel choke up again and i have to push hard again for the remaining 25 mm.
Mind you this is not a whole lot different from my old 600 mm superior barrel.
The 600 mm barrel only have the choke for the first and last 25 mm, but along the length there are a few more grippy spots but very small.
The new barrel i can drop a 20 grain Zan slug in it and it go in to flush with the barrel, on the old 600 mm barrel the 20 grain slug still have 2 mm to go when it is "seated"
So i think maybe some changes have been made in the breech end, or maybe cuz it is a Heavy liner it is a bit different here.
Shooting the rifle with the regular superior 600 or 700 mm barrels and seating a 20 grain slug, it do take a bit more effort than a shorter 13 grain slug.
even more so if its a H&N slug which to me seem to be a harder compound the slugs are made of.
So i looked down the bore and the groves in the new heavy liner are less pronounced than the standard liner, this can also be seen on the pellets them self, the standard barrel do leave the flat spots you would expect on the slugs, but the new 700 mm heavy barrel, well i pretty much have to imagine i can see those on a slug or pellet run thru that barrel.
I dunno, nothing to do but wait until my Maverick are ready for pickup in the shop where it is getting its broken cocking lever fixed.
Also found out there will be no shooting new years evening no matter the weather, my friend is otherwise engaged, so i will have to figure something out soon, or spend the night on the computer.
