My long gun and Carbine love the Baraccuda Match, JSB Heavy, Kings (tuned way down) Neilsen Ammo 49gr HP .252 With each ammo adjusting the power to find the sweet spot, working it up as psi drops. Play with her and you will be amazed at the accuracy and power. Best of Luck
AG has a 13% off sale today only .... so I bought another 12 tins of JSB King Heavy Mk I's;- )wll2506
Cool Beans Brother Man!!!!! Both my Sumatra's .25 love the JSB MRKII and original Heavy pellets!! That is a great pellet, takes down game like nobody's business. Like always, keep track of your power settings and you will have HUGE success!! Sumatra is a great hunter and pellet friendly gun. Enjoy your Sumatra Brother Man
