Ported barrel observation
Interesting observation yesterday evening while viewing 2 different shotgun being discharged for the first time...
Both shotguns were 12 gauge, one a 930, and the other a Weatherby SA-08.
First time firing for both shoguns. Identical factory loads (3.1/4 dram, 1 oz of 8 shot) were discharged.
The shooter, my 29 year old Daughter, an avid upland bird, duck hunter and big game hunter).
The test- unbeknown to her, was my observation watching muzzle rise or jump upon shooting. IE., does the muzzle porting on the 930 assist in limiting the amount of jump?
Observation: There is a very obvious difference in the amount of jump muzzle jump with the 930 being substantially less-close to 4 inch difference.
The shotguns do differ in weight, with the 930 a small amount heavier, while the stock configurations are close to identical.
So, weight can make a difference, HOWEVER; there is a noticeable difference between the two shotguns. A noted gun writer had written, "the porting was useless and only served to make the shotgun loud." Our simple test with a small frame female showed there was difference between the two shotguns.
