Anybody here ever played with Teludyne-modified rifle barrel?
I have no affiliation with the company whatsoever. I was so impressed by the technology and the owner's generosity by allowing me to hone LRS skill with tons of 300 winmag rounds that I promised him I would put the word out. I say what I mean and do what I say so here goes:
From the website: "The StraightJacket™ eliminates barrel whip, draws out barrel heat and brings recoil under control"
I am a trained skeptic due to previous engineering work where we had tons of sales contractor pitching the latest pixie magic dust. The premise seems simple: Wrap the barrel with a high grade heat sink so the barrel is at constant temperature closest to cold bore. Consistency in variables ie. temperature translates to accuracy. However, the fact that the straightjacket mod eliminates all barrel free-floating I thought accuracy would go south as a trade off for faster cooling. I thought wrong. Shot 10 rounds back to back then stuck a finger into the chamber. It was just as warm as the sun on my skin. Not much heating on the barrel either. Certainly not enough to cause mirage and distort view through the scope. Perhaps even cool enough that the round can be left in for long time without adverse effect at long distance. I had a phobia when it comes to 300 winmag after a cruel co-worker let me shoot his feather-weight hunting rifle chambered in that caliber the first week I started to learn how to shoot many years ago. I was proven wrong again with my recoil anticipation. It was like shooting match service rifle in 5.56 offhand. Nothing more. Finally, the accuracy was wunderbar still even without free floating. The overall group below ain't that great. I didn't have good sock, flimsy rest, sweaty cheek kept slipping, and my PRK-shaven cornea was burning as sweat got to it (enough excuses yet? :D ) While I was in the zone though, the three shots in the middle occured. Two of them shared just about the same hole. I have no doubt the rifle (barrel mod) is capable of 1/4 MOA easy. The weight increase from the mod was not significant.
Once I've saved enough ie. recovered from the OBR project, I plan to get a cheapest savage with accutrigger and get its barrel Straightjacket-ed
