Thanks. I would've liked to have rented more of them, but that'll start to add up $$ fast. Right now I don't really have a preference to the trigger type, as long as it's a good trigger. I figure I can train with whatever type I pick. Thanks for the input.
Yeah, that's on my list. I'll go...
In the interest of posting more gun related threads, I'll post about how I'm going about deciding on my first pistol!
I went to the range yesterday and fondled some. I ended up renting two that felt good in my hand, the Beretta 92 (A1) and the Sig P226 (E2 grip). I'm leaning toward heavier...
Oh another cool thing about the Aero Ultralight, I put it back on my rail yesterday and went to sight it in, and found it was still dead on after re-mounting and it's not even a QD mount!
Don't worry, I went to the range today but wasn't happy with my shooting so I'm sitting this one out. I shot the 25 yard a few times and the best I could get was 12 points twice!
I would think it's unnecessary, the mounts are designed to work without that. The only thing I used on my mount was non-permanent threadlocker for the screws.
The Aero Ultralight mount right? Good mount, but it's a pain in the ass to install since they're vertically split rings. When you tighten them it rotates the crosshairs, so it's tough to level them well. Not impossible, it just takes trial and error.
I tried looking for the video I saw, but can't find it. So I'm not really sure if it actually 'pierces' it so much as blows a chunk out of it, but the end result seems like it's effective either way.
In another video I've seen, in slow motion it actually shows the bullet smashing into a cylinder shape and blowing apart while punching a circle out of the armor. In this video does he ever say if they're actually bullet pieces or pieces of the steel armor stuck in the gel?
It's the red dot, man. Red dots are great, but you just can't see your small jittery movements through it while you're trying to shoot inch groups at 100 yards. Guaranteed your rifle and your higher dollar ammo can shoot tighter than that. I would say these groups are as good as you could hope...
Ok well I sort of had to piecemeal together data from 68forums but I think my numbers are generally correct, if a little rough. For 6.8 SPCII I'm using 85 gr TSX as a base. I'm getting that out of a 10.5" barrel for 6.8 vs .300 you are getting an increase in terminal energy of about 11% up to...
That was a main part of the original intent, but I don't think it's the only point of the round. I think it's the most efficient round with supers in short sub-12ish inch barrels.
I thought people were saving a lot by using plentiful .308 bullets and cut down 5.56 brass for cheap ammo? Or am I...
Like dsdmmat said, 110 gr isn't a practical weight for 5.56. I've actually never heard of any that heavy, but they may exist. I picked 64gr Gold Dots since they are known for good terminal performance and there is data for it out there. You could go heavier like 75gr, but the terminal...
For really short barrels and 0-200ish yard ranges, I think .300BLK is perfect. Once you start getting into around 12" or longer bbl territory I would start to go with a 6.8 caliber instead, such as 6.8 SPCII or .277 Wolverine.
No I get your point. I'm just saying they were softer targets. No offense meant, I just think analyzing caliber performance has its place in choosing the best gun option for one's self.
Um, ok so he was able to "take down" "quickly and effectively" 3 senior citizen women, a 52 year old man, and a teenage girl with 22LR. Based on that I'm not going to decide to use it as a defensive caliber unless I have no choice. You can effectively kill a person with a pencil to the jugular...
I'll say, just from the looks of it, that permanent cavity from the Barnes TAC-TX .300BLK 110gr seems much nastier than the one from the 5.56 64gr Gold Dot.
This is a really good one that has a great view of the permanent cavity:

HPR 110 gr TAC-TX fired from 8" AR15.com upper into calibrated 10% gelatin

...or in our case fixed mag "pistols".
I wanted to compile some data I've found comparing SBR length ARs using .300 Blackout or 5.56. In the future I plan on doing a fixed mag AR pistol and wanted to see the terminal performances of each for short barrels for use at short ranges. This stuff may...
Thanks for everyone's comments. Seems similar to other discussions I've read, some people like em and some don't think it's worth it. Maybe I'll just have to try it for myself.
But at how many rounds do you think the heat would become too detrimental on a semi auto, and how bad would it even get? If it only opens up groups by like 1 moa, then maybe it doesn't even matter.
What are your opinions on pencil barrels for semi auto rifles (and also on lightweight contour bolt actions if you'd like to add that)? Of course they heat up faster, but with a quality barrel maker does it make a big enough difference to matter much? I'm not referring to match precision, bench...
