WesternmassmanRemington Ultra 7mm mag Velocity?
Does anyone know the velocity from Remington's 160 gr 7mm mag Ultra?

stubblejumperIt is possible to exceed 3300fps in a 26" barrel with proper handloads.The only way to know the actual velocity of a load in your rifle is to chronograph it.The manufacturers claims are often quite optomistic and few rifles will actually live up to the claims.

257wbyReloaders nest has some data on it as listed below. I also have some that I received from the tech folks at Barnes. They were quite helpful. Nosler on the other hand was like tits on a bull. Hope this helps.

DufurI get 3400 to 3500 depending on ambient temp with a load of 95gr RL25 and 150 gr partition w/ fed 215 pr. have shot it in searing heat--95 plus and no press. signs. no ejector marks either. think you could get more with a little experimentation with powders but this shoots .75 3 shot groups at 100. kills elk/deer dandy. chrono'ed 15 ft from muzzle. work up from below as with all loads as each gun is to itself on its limits and likes.

Dufuroops. I had better read the post a little better.... you want to know the factory load velocity. better just shoot it and chrono it. my opinion is to handload for the 7 rum. don't waste your time on factory loads. you can make it shoot pretty good usually. although...I had some factory 140 gr partitions that shot about 1 inch and chrono'ed at 3475-3500...yes they were remington. I believe they are the only major manufacturer to produce ammo for the 7 rum. Don't shoot the barrel hot on a 7 rum. 3 shots max and cool down. I set mine in the rig and let one a/c vent blow right up through the barrel. cools rather quickly. Turn the rest of the vents off and you get more blowing power through the one.

fredj338Wow, I can get an easy 3200fps from my 26"bbl. 7mmDakota & it uses less than 75gr of powder. The term "overbore" comes to mind.

And the 7mmstw will produce about 3300fps with less than 80gr of powder.
