with the details of your rifle and I will get you a quote.
judging by the two rounds your comparing, the STW and RUM, it seems you are looking at high performance rounds. Another one you may be interested is my newest baby in the family, the 7mm Allen Mag. Just brought the first one to life tonight.
Based on a 338 Lapua case with the Allen Mag shoulder configuration and body taper. Because of the shorter parent case, you can seat bullets out of the powder capacity farther then the RUM with a 3.700" OAL and have a usible powder capacity of 118 gr compared to around 104 gr for the RUM with same bullets and both seated to an over all length of 3.700".
I would agree though, if you will be shooting this rifle alot, the 7mm-270 WSM or standard 7mm Rem Mag will be much easier to get into and last longer as well in barrel life.
If its shear Ballistic HorsePower your after, you have my E-mail!!!
If that damn Hunt101.com was not down I would post pics of this short, very fat powerhouse!!! Combined with the 200 gr ULD RBBT Wildcat Bullet, nothing will run with it ballistically if she proves on the range what we think she will do!!!
As soon as Hunt101.com is back up I will be posting pics of my new baby.
