What do these mean, and what's the difference in them? I've googled the terms, but I don't understand the meaning/difference aside from what a full metal jacket is

223 cal

223 REM 55gr FMJBT 3050 fps - Full Metal Jacket Boat Tail

223 Rem 52gr BTHP 3050 fps - Boat Tail Hollow Point

223 Rem 55gr PSP 3050 fps

223 Rem 55 gr V-Max 3050 fps

I know PSP is pointed soft point. V-Max is Hornady's ammo. I think it has a ballistic tip on it. The others, no idea.

to clarify - what does boat tail mean?

what does psp stand for, and what does it mean/do, etc -- that was answered above already though

ultimately, my buddy was looking at ammo for target shooting, and i didn't see plain ol "fmj" there were all these options, we didn't know what they meant or what they do

223 REM 55gr FMJBT 3050 fps - Full Metal Jacket Boat Tail - That is a jacket that goes around encapsulating the bullet leaving the open core in the back. the boat tail is tapered like a sail boat int he back so it a more 'aerodynamic' bullet.

223 Rem 52gr BTHP 3050 fps - Boat Tail Hollow Point,.... this is the same design in the back but the lead is swaged from the top ending with a little hollow cavity and space at the point. So the base is solid copper with that hollow point and in the tip you can still see the little needled size hole in the tip.

223 Rem 55gr PSP 3050 fps These are Soft Points. Similar than the hollow point but the copper cup is shorter and swaged with the lead coming ouside showing a little lead tip. These expand very well even at moderate to low impact velocities. Some are bonded so the lead and jacket stay together. This can be boat tail too. In .223 most are flat base.

223 Rem 55 gr V-Max 3050 fps[/QUOTE] Vmax is a brand from Hornady. It is like a softtpoint but instead of lead in the tip you have a polisher tip. this tip is also good to initiate expansion but the advantage is that it is very uniform, doesn't deform upon loading from magazine and also more aerodynamic. This also has a nice boat tail in the higher grain ones in every caliber they are available.

Makes sense?

Yep, v-max has a red pointed polymer tip on it.
Unless it had a green plastic tip, in which case, it becomes ZOMBIE-MAX! :eek:oh:

Also, when looking at the velocity, make sure to get barrel length.

Sometimes manufacturers will "cheat" by shooting rounds out of a 18"-20" barrel. If you're using a 16 or 14.5" barrel, you're not going to get the same stats.
