Sectional Density (SD) is the same irrespective of bullet shape, here is a list of 6mm SD's: 55-gr .133; 58-gr .140; 60-gr .145; 65-gr .157; 70-gr .169; 75-gr .181; 80 .194; 87-gr .210; 90-gr .218; 95 .230; 100 .242; 105-gr .252. | Here's the SD equation: SD is the ratio of bullet weight to the square of the bullets diameter.
Example: | .243 X's .243= .059049 (65-gr / 7000 grs per pound= .0092857 / .059049= .157-SD) Figure your own caliber/bullet SD.

If you notice any of these signs below, stop shooting and find the cause before firing any more.

I filled an empty plastic one gallon milk jug with water and shot it with the new 95 grain SST bullet. It appeared to be one of the most explosive bullets I have tested in my .243 Winchester. The hydraulic shocking power of this bullet on broadside lung shots ought to be devastating. 

On 10/17/04, I filled 3 one gallon plastic milk jugs with water lined in a row at 15 yards and shot them using my Remington 722 with a 22" BBL, in 243 Winchester using the Hornady 95 grain SST bullet and 44 grains of RL 19, Fed 210 pri.  It blew the first two up big time and went through the third one gallon jug of water. This should be a very good terminal performance bullet on deer in the 243 Winchester caliber cartridge.

Work loads up to the levels that begin to show pressures and then back off! Never leave your cartridges where the sun can shine on them as it will cause pressures to rise  to dangerous levels, especially those loaded with ball powders. Mine is a 722 Remington in .243 cal., I used a 7.5 lb rifle weight for all the recoil figures above. A .308 Winchester using a 150 grain bullet will run around 18 ft/lbs of recoil. These .243 cartridges are a real pleasure to shoot! Use hearing protection!

My latest .243 Win., terminal bullet performance test information
100 grain bullet Sectional Density (SD) is .242
100 gr. Hornady | RL 19 | 43-gr. Max 3,000 fps | Fed 210 pri | deer | Recoil: 11.64 ft/lb
100 gr. Nosler Partition | 44 grains H-4831sc | Fed 210 pri | recoil | deer

Here is the 25 yard .243 Winchester 100 Grain Remington Premier Core-Lokt Ultra Terminal Bullet Performance Test, I Promised.
I used three (3) back to back one gallon capped plastic milk jugs filled with water, and another 1.56 gallon clothes washing detergent plastic jug filled with water, backed up with numerous old magazines. 

The 100 grain Remington Core-Lokt Ultra bullet demonstrated tremendous explosive performance on the first jug going through all four back to back jugs and was found in front of the magazines.  At only 25 yards the mushroomed bullet weighed 84.8 grains with an over 2X, .489 caliber diameter expansion that went past the base of the bullet.  Now (11-07-05) Remington has the new 243 Winchester 100 grain Remington Core-Lokt Ultra 'Bonded' bullet. I plan to try the new bonded cartridges in 243 Win.

This was very impressive terminal bullet performance weight retention for close range shots on deer or elk! These bonded bullets will be more dangerous to shoot in respect to ricochet and shoot through scenarios, use extra caution! I would like to see the .243 Winchester 100 Grain Remington Premier Core-Lokt Ultra perform on Elk. A paralyzing knockdown anchoring kill "shot placement," is 3 to 4 inches below the top line just behind the upper area of the shoulder.

The 100 grain Nosler Partition bullet blew open three (3) back to back one gallon capped plastic milk jugs of water sitting in a row at only 16 paces and was still going, with no bullet recovery. It performs very well at close range.

Let me know how this NEW bullet performs: "Remington Premier Core-Lokt Ultra" Ammo
The special bonded construction retains 85% of original weight and delivers controlled expansion "up to" 1.8 times the original diameter.
Serious performance from point blank range "out to 500 yards."

Cabelas.com may have the NEW 100 grain "Remington Premier Core-Lokt Ultra Bonded" Ammo in 6mm .243.

Forget about shooting deer at 500 yards with any bullet with a standard 243 Winchester cartridge, follow Rick Jamison's advice.  Rick Jamison writer for Petersen's Hunting Magazine, July 2002, p- 20, Guns & Loads Article Long Rangers, - says in essence, that for deer sized game you need a minimum of 1000 ft/lbs of energy and 2000 ft/sec velocity at the impact range for adequate bullet expansion. For deer the bullet needs a sectional density between .215 to .265 and a high ballistic coefficient for long range shots.

Sectional Density is the same irrespective of bullet shape, here is a list of 6mm SD's: 70-gr .169; 75 .181; 80 .194; 87 .210; 90 .218; 95 .230; 100 .242. Here's the SD equation: SD is the ratio of bullet weight to the square if the bullets diameter.
Example: | .243 X's .243= .059049 (65-gr  / 7000 grs per pound = .0092857 / .059049= .157-SD) Figure your own caliber/bullet SD.
The 6mm 55 grain Nosler bullet ( .133-SD) has a higher BC "than the 55 grain bullet .224 bullet" which has a higher .157-SD; 60-gr  is .171-SD. Otherwise, it's my 243/06 wildcat 95% of the time on coyotes, with the 87 grain V-Max bullet, SD .210, BC .400.

Rick Jamison considers, an Sectional Density of .140 as a minimum for coyotes, an a lower limit of .210-SD for deer! A 150-gr .308-Cal, SD is .225; 165-gr has a .248-SD, .243 Win 100 grain is .242 SD.
