In the video - the top back-curl of the cheek rest knocked off the muffs.

I'd also barrel mount that sling swivel.

Too, a nicely reduced load of AA2007H? (H4895) - about 70 to 80gr., plug of foam to fill to the base of the bullet & a 350gr. to 400gr. Flat Nosed hard cast bullet would do great on pigs - deer, sambar.
I'd expect around 1,750fps to 1,800fps.

but- might only go 1,600fps- oh well.
