Please help with load data for 8208 XBR

So made some 55 gr Hollow Points. I just cannot seem to find a load data for these projectiles. They are for .223 Rem. I can find the data for 55 gr SP's but none for HP's. Is it a big deal if I use the load data for those? Any help would be appreciated.

Yeah I have been to Hodgdon in which I think is the same. I am trying to get to loading tonight so... Thanks for the help.

55gr.-23gr./3024FPS-25.3gr./3268FPS
Straight from their pages. I shoot the max load in my AR with CCi primers and a 55gr. Mid-South Varmint Nightmare and it real accurate.
 
Ok. Yeah I was curious if it mattered switching the projectile type mattered. My AR loves the 55 v-max CCI at max load as well.

Sometimes you will see projectile type having a some influence on the maximum charge for a given bullet. probably the tip won't have so much influence as the bullet design which can influence the length of the bearing surface (length of bullet in contact with the barrel)

more bearing surface will require more force to push it down the barrel. That is why you should always start at the lower end and work your way up for each bullet type to see how it and your rifle get along.

Uhh - same load data. Hole in the front doesn't change anything.

My buddy is having good luck with that powder in .223 and .308 Looking at the data I didn't care for how high the pressures were compared to velocities. I guess thats the price you pay if you want practically no temp sensitivity, everything is a trade-off. I'll probably try it eventually in .223 but I just got a few pounds of N133 and some 53g V-maxes so that's the direction I'm going for now.

Be sure and post results you're getting, the more info out there the better.

peace.

Here is what we have been using, It does appear to be a little messy when you shoot 100+ shells blasting a Prairie dog town. I carry a bore snake when I plan on shooting more than 50 shots... We shoot in -30* to 100* so I'm glad a powder company addressed the problem. Now we don't need winter shells and summer shells.

Yeah I have noticed it is a bit on the dirty side. I have a great load using the Hornady 68 HPBT's with this powder.

The whole temp.thing is why I got to using this powder. Thanks for the info guys.
 
Beware

Old thread but no way those are .223 loads which is what the OP inquired about. These look like 22-250 loads to me!!!

Hodgdon lists the max load for 50 gn bullets as 25.8 gns at 53,000 PSI and 3407 fps. The 55 grain bullet loads max at 25.3 grains (3268 fps) also at 53K psi.

I doubt that loads of 36 grains of IMR 8208 XBR will even fit in a .223 case!
