NOOOO, NOT A CREEDMOOR!
I know Right??!!!! LOL.
We use the SMT system. If we could find a spot for 1mi or more the mounts would be further apart.
After looking at the system and trying to figure it out, no luck. How does it work. Does the device read speed or impact velocity ?
The system uses acoustic sensors that uses the bullet shock wave to triangulate the position of the bullets and sends the data back by wifi antenna. You use your wifi device to see a representation of the target and the hits.
The pic in the previous post shows an incomplete setup; the chrono and bottom right sensors and wifi antenna have yet to be placed.

This system was first made in reference to a DARPA automated response system to sniper fire. Three microphones, a computer and a rifle mounted on a vehicle. The computer triangulated the source of the shot, aimed and fired the rifle. The system was about 98% effective. It didn't give the shooter time to move. The army is testing a similar system to stop RPGs from hitting light troop transport vehicles now.
I think Idaho SS has it figured out with the 7RUM, when I saw a guy on the bench next to me at Manatee shoot a 2.93 inch 3 shot group at 1000 yds and found out it was a wingtip wearin lawyer with the ugliest Sako Ive ever seen I had to try. I have solved the barrel issue when I sent in the gun to get a barrel put on it I just sent Col. Billy 2 Bartliens instead of one. Now when the group gets a little big I got another sittin in the safe just waitin to out shoot the last one
I shot a 2.3 7shot group at 1000 with a 7-300 whby the other 3 went to 14in
7Rum sounds good to me
Jumbo, let us know what you build. I'm thinking about another 7.
no ones mentioned a 7mm jazz (7mm/338 norma). anyone played with one of those.
Will do, still a few months away from a final decision.
I want to build a 7mm too, don't know which one, enjoying this thread. I was able to shoot 1 mile with a few .264 caliber rifles at Whittington Center due to the elevation, but I want to reach out further, and also be able to do 1 mile at lower elevations like near sea level where I live, and the .284 calibers with Berger EOL 195 or the 180 ELDm around 3100+ ft/sec seem like good options, and who knows, maybe Nosler will make a .284 180-185 gr RDF soon.
About the barrel life, anybody tried nitriding? If you use a pricey barrel, it seems like a good option at 2-3 X barrel life for maybe $250-300?
Nitriding will not save your throat on a severe barrel burner like the 26 Nosler. BTDT.
I think a lot of folks get too wrapped up into having the bullet stay Super sonic. There are a lot of these bullets that are handling the Transonic stage very well and able to shoot quite accurately even at a mile ( if you have an accurate rifle). But no one will try what they already have because of the Internet. Stop reading and Start to shootin.... Whats the worst to happen... You miss.. Big Woop.
Yes, but the key to going in hundred different directions is ovethinking. It's what shooters do best.
I think a guy still owes it to himself to figure just what bullets do transition well, I think I posted above the 180 hybrid has not done well for me. Then another comes along with a smooth as silk comment. So right there, contradicting advice.
I know that for myself, if I develop a load with a certain bullet, and get up to around a 600rd count on my barrel and find out my bullet doesn't do well, I'm not redoing the load because of it, I'm shooting the barrel off.
I can appreciate that. : )
