I use Baker 12/20 action guns started by Charles Lancaster in 1928 and completed by Stephen Grant in 1933. The guns are a delight to use with 1oz (28g) loads of N0.6. I shoot partridge and pheasant throughout the season here in the UK. The guns are serviced every 2-3 years by an experienced gunsmith and have proved very reliable for may seasons of hard work.
