My new Texan 257 caliber arrived today. Clean the barrel Mounted a scope and touched off a few rounds. I think this will prove to be a very accurate gun from my initial impressions. Here's my question. I am using 70 grain from the 420 mold. I spoke with Matt at R&L airguns and he suggested they be sized to .25 65. I noticed that when I lay them on the loading tray they do not want to be pushed very far into the chamber. When I force them there is still about 1/3 of the bullet that is visible. They did seem to shoot very well. I watched a YouTube video of a guy loading a .457 and he was just putting them on the loading tray and closing the chamber and shooting. This is my very first experience with a texting so any help would be appreciated. Thanks Ray
