    Bad ammunition or bad barrel? Need inputs.

    Glock 19 with Remington ultimate home defense 124gr


    Beretta Nano with same bullet


    Bullet just slides right into Nano's barrel like butter. All other types of ammos did NOT slide in. I only found 1 out of the box of 25 that slided into the G19's barrel as picture below:


    What's up? Remington's ammo slightly too small in diameter? Now, I think I know why the nano had bad accuracy with that ammo vs other ammos such as speers. The remmy ammo does seem a hair small when placed side by side with other brands. Don't have access to a caliper to verify. Also seems to me like the G19's barrel is tigher than the Nano's. Different rifling?

    Barrels of both guns are not worn out. Less than 1,000 shots through G19 and less than 500 through the Nano.

    The Glock uses a polygonal style of rifling.

    I am pretty sure the Beretta uses a more traditional style of cut rifling.

    true.. the Nano uses traditional style rifling, but the bullet shouldn't just sit in like that.

    You could always pull a bullet and mic it.

    Or slug both barrels to measure land and grove dimensions.

    Put it in the other end where the chamber is. If it does not go all they way in you have an ammo issue. If it drops in and falls out you are good to go. I always chamber check all rounds before loading them into any of my guns including reloaded and "Social Ammo". Checking them at the output of the barrel does not buy you anything as the bullets will get grooved during the travel thru the barrel. The important part is what is going on in the chamber.

    Polygonal or traditional rifling if there is not enough bullet diameter to engage the rifling in order to impart proper spin to the projectile then poor accuracy will be the result.
    Your rifled barrel will (in effect) be a smooth bore.

    Sell them BOTH, and get a S&W and you won't have to worry; The bullets will automatically know which end of the barrel they are supposed to come out at.

    Just kidding!

    How is your accuracy? If its good, I wouldn't worry.

    accuracy with the Glock is good enough with the remy ammo, but much better with the speers gold dot. The nano with the remy ammo, not so good. I have a feeling the remy ammo is a hair too small and doesn't quite touch the rifling. Gonna use these at the range and stick with speers for now on. it's too bad because the remy ammo expands very well with razor sharp edges.

    maybe it's just me, but the remy ammo on the left is a hair smaller in diameter vs the winchester on the right. notice the bullet to the shell casing... Could be my eyes again, but the shell casing on the remy ammo seem a hair thicker too. i should email remington about this..

    It would be interesting for you to exactly measure each bullet diameter .

    It's normal. Bullets need a blast to push them through a barrel.

    I think you're making an issue out of nothing. One bullet might have been sized or formed a little wacky, with an out of spec ogive. There aren't going to be any premium self defense bullets that have plain wrong diameters.

    Different manufacturers will make barrels of different internal diameters. My SR9c measured with calipers is .355". My father's older Hi-Power measures closer to .357" ish. ... but shoots fine. Accuracy is better with heavier bullet weights in that barrel.

    It seems like Golden Sabers have a 'driving band' towards the base of the bullet that is slightly wider than the rest of the bullet.

    If it chambers and shoots minute of bad guy, there's nothing wrong with the ammo. A self defense handgun doesn't need to shoot tiny groups to be a life saver.
