I have been long range hunting and shooting for years. I just picked up a remington sendero in 7mm Ultra mag. I bought this gun so I could take advantage of the 180 Berger bullet. I have recieved the data from berger and loaded the max of

86 grains of Retumbo with an OAL of 3.65.

chronographed muzzle velocity average of 2930 of 5 shots

.5 Moa groups @ 100yds

The claimed velocity from berger out of an 24in barrel is around 3050. So my 26in barreled sendero should be a tad faster than that. I know that reloading datas claimed velocity is never close to actual chronographed muzzle velocity but I feel that there should be alot more speed to be had out of this case. With the was the bullet is seated....which is way down in there to get it to feed out of the magazine....there is plenty of room for more fuel. I was wondering if anyone on this sight has loaded this round and if there is any more data for the 180 berger. I would like to see it over 3000 and have found rumors or claims on the web of up to 3200 fps, but of course no data and the ones making the claim probally have never even heared of a chrono. I know this round has a serious overbore problem which could result in increased case pressures so I really dont want to get to wild with going over bergers max recomendation without someone else tryin it first..

any info will be appreciated.

thanks...David
