Ive got a Encore 209x50. Thompson Center says you can use up to 150 grains of Pyrodex. The manual that comes with the gun has loads printed in it for all TC Sabots and bullets. They have 100 grain and a max load of 150 gr. Theve even got muzzle velocities and energies. Thanks for the help. Thats part of me checking with you guys that have been there, done that. I also read the Hogdon material. Ive read a lot of your advice Cayugad, and I appreciate your knowledge and advice. I was planning on staying with 100 gr. loads for now to see what the gun does. Going after some pigs this weekend. Thanks Again guys.
