I shoot the 7mm WSM - this is my second one. I had a Christensen Arms 7mm WSM and now have a custom Kelbly Arms. I really like the cartridge and the ballistics of the 180 gr. Berger VLD. If you do not hand load, I'd pass on the WSM, super hard to find ammo and it may be a dying breed. The 270 and the 300 seem to have a steady following, but not he 7mm. I reload mine and have a bunch of brass so I kept with the WSM. My gun is a long range tack driver. I loaded over 400 rounds to find the perfect powder type and weight, seating depth of bullet, primer and bullet that the gun loved, and now I could not be happier with the setup. I shoot 64 gr. 4831 ext, Berger 180 VLD seated .020 off the lands, Federal Match Larger Rifle Primers. For those who have the gun and can't find brass - you can use 300 WSM necked down to .284, then fire formed in the 7mm wsm and it shoots great once it is fire formed. The 7 mm and 300 have the same cartridge length and diameter at the base. Only difference is the neck size and the shoulder. There is tons of info on the web on fire forming and this is an easy one to do, let me know if you have any questions. I have done this with a couple hundred rounds and they are now my best brass. Agreed also " if it shoots good, it will do the job"
