It is a mistake to think the projectile grain weight has anything to do with recoil. Recoil is about cartridge pressure i.e. powder energetics and powder load. You can make any grain weight projectile have more or less recoil. The reason one projectile grain weight feels different from another is the amount and type of powder being used to gain a specific velocity for that particular weight projectile, not the weight of the projectile alone. I have been Manufacturing OEM ammunition on a large scale for quite a while. Not every 115 grain cartridge will recoil the same. Same thing with 124, 147 etc. It is about overall cartridge design objective. Just a friendly FYI. Very well made video by the way. I really like your channel.
Its a physics question.. to make a 145g bullet go 1000fps requires more immediate force then it would take for a 115g bullet to do the same. So you're not wrong at all (for anyone thinking im disagreeing) but boiling it down it basically means bigger bullet has "more" recoil for the same fps as a small bullet...
@@j0shll0ydmuzzle velocity and bullet weight. But you also need to know what length of barrel the testing was done out of... also the type of powder used... also the recoil spring poundage... also the rifling... the only way to know is to shoot it out of your own gun because there is no standard other then what you feel.
Probably a difference in powder & primers in the Syntech. From what little I know, the 150gr is designed to be subsonic and to have both a hotter primer and a faster burning powder. All aimed at keeping guns cleaner while using a suppressor. From the many subsonics I auditioned... Syntech 150gr was definitely the quietest.
Needed and fun comparison. I’ve never shot differently loaded magazines. I almost always have one type of target ammunition when I go practice. Ill shoot a few of my defense rounds once a year just to get some new rounds.
I've been inexpensive for many years 1st 9mm was Berreta 92s. 1987. Always shot Us military surplus 115. Now 2021 have just steel 115. Andrew making me look for 147,150 .thanks
I definitely prefer 147 and 150 grain for my compact carry guns, the recoil is a softer push and follow up shots are much easier. However for my full size 9mm hand guns I prefer the 115 and 124. The recoil is significantly less with a larger gun anyway so it doesn’t make much of a difference in felt recoil in my experience.
What do you consider full size “enough”? 4”, 4.5”, 5”? Before my kids came - grown up now - the Glock 26 felt like less recoil than the FNP 9, and a gen 3 (single not compound spring) didn’t feel any softer than the 26. I was shocked the FNP felt so snappy for its size and weight; but I didn’t track ammo way back then so maybe that was part of my problem.
I don’t know anything about guns and just bought a sar9x. Was confused about the ammo since there was so many different types. I thought the higher the grain the bigger the kick so I was always looking for high grain but ended up getting 400 rounds of 115 since that’s all I could find. Glad I made a good decision.
Depends on the caliber and the size of the case. The kick is usually related to length of barrel. 115gr will kick more out of a 3 inch barrel than a 5 inch barrel. The 115 barel kicks in my AR 9mm with a 8" barrel.
@@andrewmconradso as I return to the sport, start out with a G19 not a G26, loaded withe the 150 grain Syntech? It’s probably a little quieter too, no sound barrier crack, right?

Energy = mass * velocity ^ 2 The mass of the projectile is much less of a factor than its velocity all else being equal (e.g. mass of the gun, spring rates, etc.)
It’s nice, but a specific ammo. I wouldn’t go shoot 400 rounds of this in a range session. You’ll feel a difference in the recoil, but since it’s expensive, limit the amount you shoot
now i know federal makes a blue and purple and red syntec bullet but which one is better for going to the gun range and keeping my gun cleaner. i just want to get out to the range and start shooting and become more better with my weapon. i wish i could've made a target practice in my back yard and shoot all day but i can't lol. but help me out please
I just found some Syntech 150 gr action pistol at the local gun shop, including 500-round bulk packs. Availability, selection and prices are improving the past month. But the 50-round pack was the same price per round so I got one to try. I already liked the 115 gr range version. If the 150 gr cycles okay in my Shield Plus, I'll got more. So far the Shield Plus has been glitch-free with everything else, but those were mostly 108-125 gr FMJ and HP, all standard pressure. Not planning to use +P in the Shield Plus due to the throated feed ramp, although it's probably safe enough -- 9mm brass has a stout web at the rim -- but +P+ is probably not a good idea.
@@andrewmconrad , haven't had a chance to try the 150 gr Syntech ammo yet. I overestimated my arthritic wrists and thumb joints after my last range session in late December after getting a Shield Plus. I probably shouldn't have shot 250 rounds in a single session, including some full power .357 Magnum out of my Ruger SP-101 snubbie. Mostly it's from racking that super-stiff recoil spring on the Shield Plus. Great little carry pistol, but I'm gonna need something with an easier spring for routine range sessions. Had to give my hands a few weeks to recover. Don't get old, folks. 😬👴💀
@@andrewmconrad , hey, I just got back from the range and shot a box of 50 of the Syntech 150 gr flat nose lipstick rounds. No problems in various pistols including my own Shield Plus and a rental SIG P365 SAS. Very pleasant shooting round, softer shooting than the 115 gr Syntech flat nose. Definitely well suited to teaching beginners or routine training for anyone who needs to work on technique that might be thwarted by harder recoiling rounds. My wrist and thumb joints are still aching a bit so I'll stick with these 150 gr Syntechs for awhile for the range.
heavier bullets (147 and 150 grain) will actually hit the target higher from closer range this is because it takes slightly longer for the heavier bullet to leave the muzzle so the bullet will strike higher on paper. let's say 10 yards and in. lighter weight bullets, however, will impact lower because they shoot out of the barrel much faster. in regards to hollowpoints, lighter-weight hollowpoints will expand more rapidly but lose penetration. heavier bullets will dive deeper into the target but can lose velocity at the cost of expansion. 124 grain is a good compromise. I run 147 grain out of 4.17 inch g48, however, I would suggest you do your own research on your firearm and bullet type so you can get the best performance you are looking for.
Is it reasonable to assume the weight difference of 115 vs 147 in a fully loaded magazine would dampen the felt recoil as the gun would be heavier overall.?
From Just the View watching this video... what I saw in full screen mode with a ruler on pause mode, comparing the 147 g your hand moved higher than with the other two. The "Pull Up" or "knock Up" was the least with what you say is the 115g Bullets.
I am a new shooter and the first time I shot 147gr 9mm (from the usual 115gr) I was printing low on everything...does that seem correct? However, I couldn't really say if there was a signicant decrease in recoil.
Why Pay $24 for a box of the red tip 9 mm when you can save $5 just by buying the brass tip if all you're going to do is target practice. When I want good protection I keep my 9 mm Ruger Security 9 loaded with 150 grain hollow points.
I favor heavier bullets in 9mm. My Glock 17 & 19 are both loaded with S&B 150gr. The 150's are also subsonic; advantage if you have to shoot them indoors. Good video.
My neighbor swears 140 gr shots softer then 115gr. If you Google it you find both are softer depending on who you listen to. Winchester even has a chart showing 115 is softer. Cool way to reset those plates. I shoot more accurate with 115.
the 147 and 150 you can see a difference when it hits the plates! A lot harder impact than the 115 from the increased foot pounds of energy! Probably the point of impact is a little different too, I would imagine the heavier bullet maybe hits a little lower! Have to test that on paper! Have a good one!
It hits differently from conservation of momentum. Heavier ammo typically has less energy than lighter, since energy squares with velocity while the velocity imparted on it with the same charge is linked to the -1st power of its weight.
@@andrewmconrad I have everything from 108gr to 147gr in 9mm and didn't really feel a difference when testing them although I'm sure I would feel it if shot a whole mag of each(too expensive these days to test all my carry ammo that thoroughly😂). Usually train with 115gr
Nothing to do with the difference in grain weight and everything to do with different skus/brands/lines of ammo and your brain thinking you can notice a difference. Lol
The 150gr are USPSA loaded to meet minimum power. So they are light loaded. I good comparison would be the 150’s vs the 115gr Eley USPSA ammo.
And this guy thinking he’s found the holy grail in 150 grain, never gonna find it again ammo. Lol these vids are hilarious.
What he needs is to practice. I can run a plate rack with my revolver division 929 faster than that lol
Shot 150 grain for the first time 2 days ago, such a soft smooth feel compared to the 115 grain
So smooth
Does it hit harder compared to 115 grain due to heavier weight and slower velocity ?
@@TheRealB1gA it's probably just less pressure, if heavier slower rounds kicked less 45acp would be a breeze to shoot
