I’ve no practical experience at International and know it’s more difficult than American skeet , however my 12 gauge average took a noticeable improvement when I quit the Remington 11/87 in the 12 gauge event and shot the Krieghoff with 20 tubes in the 12 gauge . I always thought it more the same feel . But for awhile I played with 20 gauge 1 ounce for the 12 event . The ounce loads broke the targets plenty well enough but it was a lot more comfortable once I started using the same 7/8 ounce loads I used in the 20 event .
