I must out myself on a mistake I made.
Worked up loads, using same bullet, for the .300 WSM and the .30-06 prior to the MN firearm deer season. Reloading and range time went off without a hitch. First time loading 185 Sierra Game Kings for each of them.
Rounds fed and fired fine in both the Savage Model 11 .300 WSM and the Weatherby Vanguard .30-06.
Brought both rifles to camp the first weekend. I chose to carry the Savage and all was well except for the lack of whitetails.
Second weekend decided to utilize the Weatherby and did not bring the Savage to camp. Left it at home in the cabinet.
Got to the stand, Scent wicks out, sent my boy up, I climbed up, hoisted our gear and unloaded firearms up.
Loaded the lever .30-30 for the boy and then the .30-06. Didn't see anything that morning. Time for lunch I unloaded the .30-30 and lowered the boy's gear and rifle. Worked the bolt on my rifle and I was treated to a bulletless case and powder spilling into the magazine.
Back at camp a tap with a cleaning rod dislodged the bullet. Blew it out with the compressor. Next times out to the woods I loaded the magazine but did not chamber. I figured I would chamber if I was presented with a shot.
Rounds are loaded to correct OAL. I did not notice any issues in feeding during range sessions. I must not have needed to unchamber a loaded round. Different bullet I have never used before. I assume ogive is a bit different causing it to just enter the chamber enough to stick. Load was very accurate in the .30-06.
