Let me start this by once again saying -
that mathematically the 40x215 CF should not shoot from a slow twist rifle.I was able to get to the farm this morning and the mission was to shoot the new Lehigh 40x215 CF bullet. If you read the previous post you know that I mentioned that I had shoot a couple of 215 yesterday while shooting the new 40x185's. Those two shots indicated that there might be some hope for shooting this new bullet from a slower twist rifle.
This morning was a little warmer than yesterday day but I really wanted to do this activity. So headed out to farm to get setup. At the farm I placed the target near the same spot as I had yesterday - I forgot the range finder so I could not get the exact distance. When I paced back to the shooting bench it was 123 paces - so I believe I am very close to 100 yards.
Also a thought to consider, I was shooting a 110 grains of T7 for this shoot. I normally shoot 120 grains while hunting but since these bullets should not shoot from the 1-30 I did drop the charge hoping to induce the tumble if it were going to happen. Another factor that might play into this is that I am shooting at about 2600 ft. of elevation in high 70* temperature.
I ended up shooting to groups and a OOP's. The OOP's was my own doing trying to move the front Caldwell rest to the right with my left hand while the right hand trigger finger was on the trippger - OOP's.
The first group was shot with my normal MMP Tan sabot the second group of 3 was shot using a Harvester Light Blue Sabots.
Here is the target... Even with this target -
Nothing has really been proved about shooting this bullet shooting from a slow twist 45 cal. rifle.
I really did want to set the target out to longer range but walking through the Garbanzo Field sounded like I was killing 100's of big beetles and I was even trying to be careful. At some point I will get those long range shots...
