7mm/300wsm

Any thoughts on 7mm/300wsm wildcat. Norma or Lapua brass is a must in my closet so until the 7wsm picks up desired brass i'm a bit stuck in my decision on build. 7-08 AI is an option also. 28" is new thought as I just sold 26" brand new krieger Blueprinted 700sa is my base.

The 7mm WSM does look interesting. You can always go 7mm SAUM but then again if you do not want a barrel burner the 7mm-08 AI would be a longer lasting option.

As far as barrel length going longer then 26" I seemed to learn the lesson. Short and stiff beats going long unless you want to take advantage of a big case to burn lots of slower powders or need iron sight radius. Having to deal with barrel harmonics becomes a bigger problem (maybe not a "problem" but just one more thing to deal with) the longer you go.

Why? There is a perfectly usable cartridge called the 7mm WSM. What would be the advantages?

As I mentioned, until the 7wsm has the option for norma or lapua brass im just not interested and the 7wsm actualy has more case capacity than the 300wsm case. Small amount ,but enough to take advantage of the better ballistics with 300wsm case. Downside being wildcat in case I decide to quit reloading.(Won't happen)

Rossman, lol yes a LITTLE bit of barrel life maybe. I steered clear of the 7 & 300 RUM and went with standard belted mags for the simple fact of not being a pro shooter just a small local oriented shooter I would benefit more from the barrel life over the small velocity increase it offers. Although the 300 RUM Sendero is fun to shoot, but just not cost effective on a custom build. I have however been considering the 7mm-08 AI because as far as I can tell throat erosion isn't a major factor. I can fire form with soap and save bullets. But as far as harmonics it's a bit more involved than the limb saver barrel dampener huh? lol
