Having an issue with my 1.5" swivel and keeping it upright. I fire a 1# lead ball over 500 grains and hold on to the tiller when she fires. However the recoil causes it to topple sometimes. I've tried staking the front leg and weighting it with sand bags but it's still a chore to keep it upright. Any ideas appreciated.
