I have been using Sniper Medium Pellets in my D34 and Tx200. Very accurate pellets with a great ballistic coefficient (0.029). These pellets provide a nice flat trajectory from 18 to 40 yards in both guns, assuming a spread of one pellet diameter. They also buck the wind better than JSB/AA 8.4 gr dome pellets better. Accurate! I recently shot a 196/200 score on the GTA 30 yard rested target that I will submit this month. In my TX200, I have been lubing the Sniper pellets with FP10 lube. Just use 1-2 drops for 100 pellets. This keeps my barrel from lead fouling. If I don't lube the pellets, I need to clean the TX barrel every 200 shots. I do not lube the Snipers in for my Diana 34. They shoot fine right out of the tin.The unfortunate part is these pellets are back ordered at PA until August 30, so I will have to use my second best pellets in the D34 (AA8.4gr with 4.51mm heads) and TX200 (JSB 7.9gr Exact Express) until then.
Fred, Field Supply doesn't have a Buy 3 get 1 free deal but they always have the Sniper Mediums in stock and have always been my go to place to get them. Right now, they're currently $12 a tin during a sale they're having. Packing while not PA style has always been good when I ordered and they have a flat $3.99 shipping fee to help save you a little. Just scroll down until you hit the pellet part of the sale:http://www.fieldsupply.com/uc-20170704tu4.html
