My experience is basically the same as everybody else's. There's always some velocity loss when shooting standard ammo in an improved chamber, but exactly how much depends on the powder, bullet, etc. I've owned rifles for several "improved" cartridges, but can't recall a loss of more than 100 fps.
Accuracy is usually good with fire-forming loads, but how good again depends on the load. If the bullets are seated crooked in fireforming loads, then they probably won't group very well, but if the loads are put together correctly then accuracy can be outstanding. My fire-forming loads in several rifles have been accurate enough to shoot ground squirrels and prairie dogs at 200-300 yards. I'm envious of you Montana varmint shooters : Ground Squirrels at 200 lined up with Prairie Dogs at 300 ! Now That is Shootin ;-)

The 280AI is as fast as the 7 RUM, accurate as a 6mm PPC and easy on barrels as a 22 short.

My 375AI does not notice the difference between fireforming loads and full-on hunting loads. A number of folks here have shot their best groups ever with it. Many nudging a quarter-inch at 100 yards with any number of different loads.
A fireforming session some time back with several different factory loads and several varieties of handloads produced a group of just over an inch with about 50 shots and four shooters.
Mark Begich, Joaquin Jackson, and Heller resistance... Three huge reasons to worry about the NRA.

The 280AI is as fast as the 7 RUM, accurate as a 6mm PPC and easy on barrels as a 22 short. Pretty much agree on all points except barrel wear. I've shot a lot of deer with one of mine and had to replace the barrel 3 times in the process. The first barrel was a Hart manufacture and it lost its mojo at about 600-700 rounds. Other manufacturers barrels lasted much longer though.
