Thompson Long Range Shooting School

[nmkid]

First of all, I apologize for not displaying pictures or videos from the website. I tried, but couldn't do it. So one of my nephews calls me, all a buzz about an LR shooting school. I went to their site and everything is pretty much SOP until I start reading about their twist match bullet. Thoughts.

How it Works​

By cutting groves through the radius of the Ogive, it was obvious that I could keep a shorter nose yet increase the surface area. If the groves did not match the twist of the barrel, the test was pointless. I tried several depths, widths, lengths, and the number of groves, most all through a 1in 10 right-hand twist rifle.


What was noticeable right away was the accuracy, consistent tighter groups at several distances out to and including 1200 yards with the Twist Match bullets. Remember, my comparison was with the exact same bullet with no groves, modifications were made so weights were the same, and muzzle velocity was also the same.

Calling Bryan Litz. This aught to be good. Is it APRIL already????

Thanks.

He says "we work exclusively with the Weatherby 30-378 no personal rifles are accepted." I couldn't understand why the prices were so high but if I had to feed and maintain barrels on a few of those I would he expensive too.

 

[jelenko]

Wait. He states "Somewhere along the way I knew that if I could increase the surface of the nose or ogive of the bullet, I could reduce the resistance."

Uhh - drag is proportional to surface area. By increasing the surface area, he is increasing drag. This is fundamental aerodynamics.

 

[3Sigma]

Meh, pretty obvious he has no background in compressible flow dynamics or fluids, or even physics.

Doesn't mean his idea is without merit. There have been a number of breakthroughs by laymen in their respective fields, so I try to keep an open mind.

But, there is a significant lack of data and detail necessary to make that judgment.

Mr. Demming said it best:
"In God we trust. All others must bring data.”

An older friend of mine and his cousin both attended this shooting school years ago. They shot Weatherby Accumark 30-378 rifles at the school. My friend miraculously shot the best group at 1000 yards ever of any student ever and was offered a special price on the rifle because it was so accurate. Of course he bought it. He could never duplicate the rifle's 1000 yard accuracy, even at 200 yards. I never told my friend he was scammed but I think deep down he knew.

There is always a select group that succumb to "banana republic" marketing.....

If the bullets are only for the Wby 30-378 then he has a very limited market - not smart IMO.

It would be very difficult, nigh on impossible to produce for all of the different twists out there.

 

[Coyotefurharvester]

Golf balls are accurate,lol.

 

[jelenko]

Hmm. Do the lands engrave similar channels in bullets?

 

[JLT]

Golf balls are accurate,lol.

Dimpled bullets are next. I suggest an icosahedral pattern with two different dimple sizes . . .

Appears next to ridiculous to me as I analyze it.
Not all rifles, say, in 30 caiiber have the same twist some Weatherby 300 mags were 12 twist, as many 308 winchersters, but some are 11.25 any yet some 10 twist and then 300 PRC is 8 twist. What about gain twist? A twist matched engraved bullet for each twist seems...impractical for many reasons... Adding another variable to have a positive influence? Will, how you index the cartridge as it's chambered, make a difference as the presence of external grooves will not be in the exact position in reference to the barrel rifling for each shot? Are the external grooves perfectly balanced and symmetrical? First rifling is not actually exactly consistent throughout the bore, close, but each is different, and inconsistent ...as the rifling button turns. Dan Lilja of Lilja barrels used to check the consistency of the twist years ago, and wrote articles about it. Even computerized rifling, but it would probably be closest to perfect...but they aren't as I have checked brand new expensive CNC milling machines before they go into production ...and you might be surprised when they are seriously tested and their flaws magnified. You have to decide if it's capable of continually holding tight tolerances of specific manufacturing jobs.
The rifling will spin the bullet, regardless of what grooves are added to part of the bullet surface...Shotgun slugs with exterior rifling, to take up barrel dia differences more than impart spin, those same shotgun slugs fired in rifled shot barrels and smooth bores..slow motion. The rifling works to spin the slug fairly consistently but not so in the smooth bore its flight is more dependent on aerodynamics of attached wads and heavy frontal mass to propell it somewhat straight in oscillating pattern toward the target..
So, no on this one ...for me.

After all these years, someone has come up with a better bullet design than the Herters "Wasp Waisted" bullet

Say it ain't so, Herters bullets are used by the royalty of Europe along with all the other Herters branded products. At least that is what Jacques Herter used to say in his catalogs, and I am sure he was not over selling his products. Herter's catalogs were always a great inspiration for wish lists as a kid. I still have a couple from the early '70's.

Those and a slick page Remington brochure, I could look for hours at the different cartridges and rifles.

Stay away from them and their "must buy our 30-378".

Way too many options if you want long range training.
