Your slide likely wasn't going into battery because the 40 you fired prior to the 10mm left a carbon ring in the chamber. Ever fire 38's in a 357 revolver then load it with the longer 357's? Same idea. And a bullet shedding a little weight during penetration isn't bullet failure, especially with a non bonded bullet like the xtp. To be fair, that xtp performed exceptionally well considering the impact velocity is at the very upper limits of its threshold
My M&P (4") gave me 1312 fps for the Hornady Custom 155s. A very different velocity than what he did here. 1600+ is insane. In the neighborhood of 900 ft-lbs!! But one could expect gel results to perhaps be quite different at these speeds. Also, it might even be too high of a velocity for these. Although they seem to be able to handle it. Those mushroooms looked somewhat smoother than what normally see. I carry the 155s as well but so far, just the Hornady Custom. I found video from The Gun Dungeon that has Underwood 180 gr and 2 clocked at ~1245, penetrated to 14". Another at 1230 went 16". My Hornady Custom factory 180 gr went 1161 fps. Loads of Bacon video has hand-loads of 180 going just over 1300 and those went about 18-20". Trying to figure out what velocity I want to load 155, 180 & 200 gr at is proving to be no easy task. Brass-life, ruptures, recoil, bullet-performance, feeding reliably...This video was a huge help in knowing how far a person might go.
@@ShastaBean my 180s are at 1300fps from 6@ longslide so are 200gr xtp’s…135 nosler asp screamin round 1550fps…all are at very limit of the brass and primers..I wouldn’t recommend these numbers in anything other than forged steel..
Agreed, if you could get the bullet into 10 fragments that each go 14" then its a huge win. The whole idea of the FBI standard of 100% weight retention is for puny 9mm bullets that ONLY penetrate if they have 100% retention. Bullet retention is moot so long as you have one or more pieces that reach full penetration.
I'm out here in california in the foot hills of the Sierra Nevada, close to Yosemite. It's nice but will be moving eventually to escape all the ca bs. Thanks for the comment, I've been meaning to make more videos but life gets in the way some times.
I think 800x is discontinued now. I really wanted to try some for max loads. Is there any equivalent or better? I know people like aa9, blue dot, and longshot but from what I read 800x was best for max loads with heavy bullets.
I've definitely found 800x to be magical. It sucks that they've discontinued it because anything I share using 800x is irrelevant for you guys. Only really is valuable for seeing what the bullets do at those velocities. If I remember Blue dot is slower burning so it should be a good substitute with the 200+ gr pills. The others you mentioned are decent but I'm not sure if they're a good substitute or not. I have some blue dot and longshot so I'll start to throw some lead and share my results.
800x was definitely the best juice for 10mm. I used to load the crap out of it. You could push some serious velocities in the 200 grain bullets without showing any pressure signs. It was magical powder. Metered like shit but an exceptional powder. Shame they don’t make it anymore. Longshot would be best for heavy loads. AA9 is best for lighter loads.
Yeah it's really getting up there. Been trying to get to 1,000 ft-lbs but I think I will need to go to 135gr nosler hollowpoints or roughly 150gr cast lead with a wide metplate.
@@letstalkcaliber704 I like the 135 grain noslers, but at velocities like that I think they’ll be .40 caliber grenades lol. Maybe a light solid copper round?
They're both substantial. I'd say the 155's are slightly tamer but you'll still need time between shots to get back on target. I've mag dumped them but it's not pretty.
Did I not say it in the video? 800x 9.6 gr. Winchester large magnum pistol primers. I developed the load after reading many forums and reloading manuals.
@@letstalkcaliber704 Thanks for the response I heard you say 800x but I had no idea what that was... I do all the old-school powders because I'm old school... 😆... The reason I questioned the velocities is that they are so high... I just ordered my first 10 mm and it is a caliber I have never reloaded for in the past.. Thank you
@@andrewduis1881 no worries. If you have some blue dot laying around it's also pretty excellent in 10mm especially with the larger 180 and 200gr pills. Im using 6in barrel so my velocity's are a little higher than the manuals.

Blessing to you and I appreciate your video and wisdom...
I probably need to replace the spring it's about 5 years old and has seen quite a few rounds. Could also just be the kkm barrel is extra tight in the slide. Don't recall having issues with the stock barrel. Either way I'm not particularly concerned because its not a defensive weapon for me.
@@letstalkcaliber704 Exactly. I got a kkm compensator for my G21. It looks polished and feeds well when I "rack it". But I got the Grindhard 111 grain instead of 45super. Which makes the weapon so light now. I haven't even shot it yet. Maybe I'll have to make my first weapon video. Im using the stock recoil spring. They claim 700lbs of energy.
@@fullbloodedchristian9206 looked it up and dam that's 10mm territory. Ya you should shoot it and upload it. I got my gel block for ~$100 on bownells. Definitely worth while to compare results.
Complete bullet failure? I disagree. If a bullet fragments causing it to under-penetrate then the fragmentation is a failure. If you got 14" from the 155 and 18+" with the 180, then you had sufficient penetration and any bullet fragmentation at that point is a bonus. What's better 24" and 100% weight retention or 3 x 60 grain fragments that each penetrate 16"? I'd rather have 3 holes than 3!
Well if you were going to shoot an elephant it be good to have that penetration and the 40 ball round does that better than the 10mm hp's but you could just as well use a 10mm ball round and be even more effective. Generally if we're not getting over the 2100 fps needed to cause hydrostatic shock you want to choose something that expands the most while still penetrating deeply enough. In that same line of thought some folks recommend ball rounds in 380 for self defense because of its weak penetration.
@@organicmaterialsciencecorp6115 man I should mention don't duplicate this load using any kind of basic powder dropper. 800x is a large flake powder and doesn't drop consistently from powder measures. You might set your powder dropper at 9.6 gr but it might drop anywhere from 8.5 to 11 grs. At this close to the top end that discrepancy could blow a gun up. I hand weigh every round when it comes to 800x. If you had a fine fake or ball powder dropper all day long.
Phooey to the people poo-pooing your video. I found it entertaining & useful. All the clowns giving advice on how to do a video, have no videos themselves. Funny.
I literally said that in the video. Frankly I think it has more to do with the bullet setting depth and the match barrel than the spring. Factory recoil spring with very few rounds has the same issue. I don't have time for re-shoots or to perfect my setup so what you see is what you get. Otherwise video wouldn't have been made at all.

You chose an awful tool for testing. Glocks have very loose tolerances. It'e doubtful you'll shoot want moderately to hot rounds with that plastic POS plastic toy.
Not sure what you're talking about. These loads match hot underwood loadings and I've even pushed it a bit further. Gun is doing just fine. Yeah the lower is largely polymer but the upper is solid steel and beefy af. Glocks are no different than anyother striker fired gun out there. They can handle as much pressure as anything else out there because the chamber is what counts for pressure and its steel. Now is a glock the nicest gun out there, no but it's perfectly capable for shooting gel from 6 ft away.
