As long as the firearm functioned normally everything is fine.Those bullets have been slowed down by the snow (like shooting into water)and actually you're lucky to see bullets in that good shape after firing.This way you can diagnose any issues with that load by getting a visual on the lands and groove marks on the bullet.They look like plated (not jacketed) bullets in normal condition after firing but I could be wrong.I used to shoot into a bundle (16 inchs or more stack wired together) of wet newspapers at 50 yards to see if I could catch my .357 and .44 mags bullets and it worked pretty good.Wet newspaper is very dense (my wife wouldn't let me shoot at her roast)and the bullets that came out, after cutting the wire and sorting thru it, were very revealing in their performance.Speer would have jacket separation almost 90%.Nosler and Sierra bullets were 100% textbook in appearance,perfect mushrooms every one,and copper jackets still on the core and looking good.Finding rifle bullets is harder.We found 2 in all the years hunting moose.Both were Sierra 180 gr. Pro Hunter models and both looked very good and hardly lost any weight if I recollect.
