Rifle bullet shapes

Postby Sagebrush » Fri Aug 02, 2013 1:51 pm

Was just messing around and have got into bullet weights, ogives and over all lengths and
how they might effect the OAL length when loaded in my rifles.
Here are a few of my .224 bullets per their weight and total lengths. You might also notice where
the ogive on the bullets are also located.
I found it interesting.................. (left to right)

55gr Speer ......oal .688"
55 Hornady ........... .659
55 Rem FMJ .......... .718
52 Speer bthp ....... .721
70gr Speer ........... .790
55gr V-Max ........... .811

You are dealing with one of the more critical aspects of varying projectiles for a given cartridge...not only is the OAL affected but the spacing of the bullet from the lands is dramatically affected. I've run into this when loading Berger VLD bullets trying to seat the projectile .010" from the lands without going over the OAL to fit into the magazine. Being so sensitive to seating depth and OAL plus the amount of meat the Bergers are destroying on a high shoulder shot I have sacrificed their awesome stopping ability for less meat damage by going back to ballistic tips in my .308 without giving up much if any accuracy. I've considered trying the new Berger Classic or Hybrid which aren't as sensitive to seating depth but as awesome as they shoot they are damned expensive.

I have also found the longer the bullet , the better trajectory it has . That was my thinking , when I put together the
6.5/284 with a 8.5 twist and it being a TNT ( tight neck turkey ) . It is a fine hunting caliber for most thin-skin north
american big game , with not much recoil and with a powder burn efficiency to push 140 grs with accuracy .

The interesting thing is , I did this 25 years ago so ,I do have a tract record for it and you can buy one already built
over the counter from some manufactures .

The 6mm or any thing close is a heck of a bullet for hunting medium game or even heavy game with the bigger bullets and a good shot placement.

I reloaded a friends 256 Newton wildcat and a 264 magnum and both put the standard .270 to shame with bullet drop
and accuracy at 400 yards that was eye boggling. Almost like tossing lightning bolts. Boy did they get there QUICK !!
Sort of like the 270 vs the 30-06.

later.

I have 2 boxes of the old style Nosler partition 139 gr bullets , in this 6.5/284 it has killed Elk out to 475 yds with one
shot just above the curly hairs and on Big Nevada BUCKS one shot kills were normal as long as I was in the pump house .
My Win 338 with 210 Nosler FB is a far shooting gun , after squaring the bolt , truing the chamber and trigger job it will
shoot 3/4" groups but , I had to put on a KDF to come it down .
