My guess is 35 Whelen or 338-06. Easiest way to find out is to use micrometer on the bullet and weigh it, then throw everything else away. Please let us know the results as we are all as curious as cats!


.375 Whelen (.375-06) … curiosity immediately drew me into that cool concept & BAMM! I’m no seasoned Ammo Guy, ‘I Need Your Help’ may have a serious contender here & maybe my 1st rebore project!?

Interesting. I've never owned an AI, but my father in laws 6mm Remington AI shoots well too when fireforming the AI case. It's his pronghorn rifle.Quality Cartridge actually makes properly head stamped brass. Crazy thing I’ve found with mine is that fireforming either from ‘06 or 35W brass, I get right around 1” groups using the cheapest 375 Speers(hot cores). I can’t say this is common place or not, I’ve never shot a fire form load on paper until this rifle and the only reason I did with it was while forming brass I stacked 3 on a steel plate very neatly and curiosity got the better of me and I stapled a target up.
The powder isn't ball. Looks like H4831SC?I pulled a bullet today. Mic'd at .34, approx. 200 grains. Powder is some type of ball, approximately. 46 grains. Seems ti line up with 35 Whelen. Lmk what you guys think, cheers.
Yea I was beating the bolt with a hammer and it still wouldn't close hahaMan, good thing you didn't try to fire them in your 30-06. I believe it's a 35 Whelen.
Not sure about powder, I don't reload so that's not my area of expertise. That was a guess but if anyone knows I'd be interested to find out what kind it is. I know its hard to tell from a picThe powder isn't ball. Looks like H4831SC?
Lucky for you! LOLYea I was beating the bolt with a hammer and it still wouldn't close haha
It's a cylindrical powder and looks like H4831SC (short cut) to me, but I may be wrong?Not sure about powder, I don't reload so that's not my area of expertise. That was a guess but if anyone knows I'd be interested to find out what kind it is. I know its hard to tell from a pic
Off topic, but a couple of years ago, my father in law, myself and a few others were shooting some clays. He was shooting his older 2 3/4" chambered 870 Wingmaster. I wasn't paying attention as to what shells he was using, but he was having a hell of a time extracting the fired cases from the chamber. Finally, I looked at the box and he was shooting 3" high brass shells! They worked, but am not sure how? LOLLucky for you! LOL
