Hello, I have a extremely lightly used Browning BAR 300 Winchester Magnum that was given to me from my Grandfather. The rifle is in immaculate condition inside and outside but I cannot get this rifle to cycle reliably. Since I have owned it I have put two boxes of Hornady Superformance 180 grain bullets through it and I have had 8+ Jams from those two boxes of bullets with multiple cleanings in between shooting. The rifle has been broken apart on numerous occasions and cleaned / oiled with no luck in reliability. It appears to be an ejection issue as the empty casing will get caught when the bolt is on the way forward to pick up the next round. It doesn't seem to matter if it is the 1st, 2nd or last round, no rhyme or reason it it. It could be the 1st shot of the day with a perfectly clean gun or the 15th shot. The last round that I shot though it was left sitting in the chamber when the bolt locked back. I have attached a few pictures of the problem I am experiencing. I love this rifle but so far it has not proven to be a reliable big game hunting rifle.
