Hey folks, I have a quite nice Mauser 98 guild rifle, sporting a mannlicher stock and double set triggers.
The stock had split and I repaired it and decided to try a cast bullet through it, however upon firing I was getting a whoosh of air or gas? Back into my face making shooting quite awkward.
My recipe was brand new PPU brass FL sized. 20gr of IMR 4227 a 180gr coated gas checked bullet seated a little short to ensure I didn’t cram the lands.
Cases came out sooty from about the neck half way down the case, only on one side however.
I believe I was getting gas back into my face because of the base of the cartridge not fire formed to my chamber quite yet. However I’ve shot this load in my straight pull M95M and had good results.
Any advice is welcome!
