That pop you are talking about was fairly common for the 224 valkyrie. Iraqveteran8888 has a video where they caught it on camera. Thin jacket bullets and super fast twist will definitely do that.

This topic is perfectly timed for me. This weekend I’ll be testing 230gr A-tips in my 300wm with 1:10 twist. They shot fine at 100 yards, but now we’ll be testing them at a mile. I was worried about the box recommending 1:9 but I was hopeful I could get away with it.

it is good to be included. i shoot targets at 100 yds off a bench at a State of Florida, park range, off a concrete bench. i learned that the 300 whisper was very accurate; compared to other .308 cal. 16" barrel, 1/8 twist, loves 90 gr thru 130 gr bullets, on a good day less than 1 min. about 2100 mv. interestingly looses 200 fps in 100 yds.

I listen to 98% of KZbinrs and it's just an echo chamber of people repeating other people's bullshit. A lot of them say they're not getting paid but I hope they are because they're just parrots for whatever is the new thing. This guy is so much more thoughtful, balanced and approaches the subject in a serious manner. I really appreciate his ethics and intelligence. I usually learn something I have never heard anywhere else. I had gotten so sick of watching videos in which I had to stomach the "creators" favorite rock and roll song from his not to distant childhood playing in the background, as I am subjected to selfies of ammo dumps or long range shooting clips that the subject tries to use jargon he seen in his most recent sniper Hollywood movie. Great job to both of you.

I would think that the faster the barrel spins a bullet, the higher the skin temperature the bullet would have when it exited the barrel. Do you have any idea how hot the bullet gets? I know metals lose strength as they get hotter. If the bullet skin temperature approaches the melting point, it might explain why the bullet seems to disappear. The remaining bullet mass may fly off in some random direction.

When I put my .22-250 with a 1-14 twist into the Berger bullet stability calculator .242 bc 50 gr. I can’t seem to get any stability to work without getting a different twist rate. Running at 3,700 fps. Can I do anything besides new barrel? Gun is a very nice Thumbhole Remington 700 with fluted barrel. I’d prefer not to replace a newer barrel but per the calculator I appears nothing is truly stable in the firearm. Any thoughts?

Would be curious to see if a projectile really tends to align with the line of trajectory on lower twist rates, or if it just starts to tumble easier. On the other hand key holing can't be good either. The only thing that can't hurt is a more flat trajectory.

Great info. I think another factor In bullets exploding after they leave the bore is friction. The friction, combined with an already hot barrel tends to anneal the already relatively soft, thin copper jacket making it that much more susceptible to stretching and ultimately rupture as the centrifugal force on the heavy core presses outward against it.

I Experienced bullet disintegration with a 110 grain tnt varmint bullet out of a 7 mm rem mag hand loaded quite hot. I was so confused as to why there was a puff of darkness about 3 meters past the end of the barrel every shot and I couldn't seem to ever hit the paper. It was about 15 rounds of me scratching my head before that idea dawned on me and your the first to confirm it . Thanks 👍 I thought I might be nuts.

With the variety of pistols & rifles I have It comes down to what manufacturers rounds shoot best out of my barrels . The problem I have is two fold . One - getting those same rounds when I run out . Two - (most importantly ) remembering to write down what shoots best in what . 😁 Appreciate all the hard work y’all do in making these videos .
