They pinned the General Walker assassination attempt on Oswald post-facto.
Maybe. Why would they do that?
they can’t duplicate...the Carcano (no such thing as a "Mannlicher Carcano”) could not be zeroed without shims.
The Carcano is a diversion, a distraction, a prop from all I’ve gathered.
I agree with where you ended up with all that, and that probably makes the individual pieces irrelevant, but some of the old bullet points that people keep repeating need to disappear from discussion.
The "can't be duplicated" thing was absurd, because many, many people over the years have duplicated it with almost perfect duplication of the conditions and less perfect duplication. I might duplicate it for fun when the weather is a little nicer.
I don't know why you're still doubting after seeing video of some oldster slam tagging that tombstone 3 x in 5 seconds... and I doubt he was an undercover Carcano-enjoyer, practicing every weekend (which Oswald was- and folks saw him at the range).
I also don't put any faith in anything the report says- either "Mannlicher Carcano," or the fact that they say 7 round capacity, but it's only 6, and then folks say "they meant 6+1," but that's not possible with the clip setup, or any of that.
I don't cheap-out on mounts, but if I slam tagged that snowman over there (I'm 4 stories up, but high ceilings... so maybe about the same height) and then dropped the rifle onto a hard surface and ran away... would my modern setup hold zero?
I'm not trying to hear any BS about shims or anything because you could bend that L mount into a 20 MOA or a 0 MOA if you wanted, with a pair of vise grips, or a more precise tool. A Youtuber replicated the second Trumpshooters SKS with optic duct taped directly to the receiver cover and was making good hits at the same distance.
I can 100% guarantee if if was a successful assassination attempt and they held up an SKS with an optic randomly duct taped to it, lots and lots of gun-guys would be screaming BS.
All that being said- I ALSO don't think LHO was the killer.
