2nd Shooting of the new Lehigh 40x215 in a 1-30 twist

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...

And a couple more pics to show some of the shooting expedition

I always enjoy your posts, even though I haven't ever shot a M/L, yet, much less hunted.

Whites in their day were top-of-the-line and even today it is awful hard to beat them.  Had Doc White been able to keep control of the company - I can not even imagine what he would have on the market today!

There has been a little concern whether these bullets were starting to tumble at a 100 yards since they were being shot from a slow twist 45. I think that question has now been answered...

I think we have answered the question about whether the bullet might be yawing or not.  SShooter has put a post about shooting the bullet this morning form a slow twist 45.  His holes looked ragged also. But his 1 hole group at a 100 was really nice and a 1" group of two shots at 200 and no sign of tumbling is even better.

Then something SShooter mentioned prompted me to go take a look at my target board. After doing that there is no question in my mind the bullets were not yawing.

Here is a close up of one of the random 40 cal holes.



All of them looked very good - I was also able to plug new bullets into the existing holes - it was a really tight push to get them in - but there they are.
