RE: Balistic tips/7mm RM/Deer
ABSOLUTELY NOT!!!!! They are excellent in my wife's 7mm-08 and friend's .270. In high velocity rounds they are terrrible. Slammed a buck in the shoulderopening day 4 years ago at 350 yards. It rolled twice and got up dragging it's leg and ran 3/4 of a mile where someone else shot it. My 150gr bt broke the shoulder but never penetrated.
Same year I used a .243 w/100gr bt during doe season. shot a doe4 times at 50 to 100 yards before she stopped getting up. two of the slugs were completely opened up against the ribs with no penetration other than the hide. the third hit the shoulder and was also completly flattened against the shoulder bone. The fourth was high and took out the spine and backstraps. This is what put her down. The shards of shoulder bone perforated the lungs, which was what finally killed her.
Both setups were handloads at about 3200-3300fps.
After thorwing all of my Ballistic Tips in the garbage, I went out and bought Nosler partitions for both. Iv'e taken deer from 40 to 550 yards and a running antelope at 75 yards. All were quick kills and all completely passed through leaving excellny blood trails.
The Savage .243 groups just under 1" and the 7 mag Sako will do legitamate .5" groups.
I guess after taking a doe at 550 yards with one shot with a complete pass thru, i no longer see the need for a little plastic tip.
