| It 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. |

| I 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. |

| oops. 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. |

| quote: Wow, 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. |
