Absolutely love my 2 7mm wsm's. Brass has been a problem but midway had win brass in stock as of a week ago. I bought 1000 rds so i dont have to worry. I shoot 168 berger hunting/target and have had great success. Never had a failure from the bullet.Im kinda getting bored with the current stable so I figured I'd change up my Tikka. Just ordered a 22" Proof carbon Sendero light in .284 8 twist to replace the current 6.5 GAP barrel and a mesa precision altitude stock to swap out the greyboe. I'm debating between 7wsm and 7SAUM but I haven't written off 7 rem mag completely yet either. I really like the lighter recoil of the 6.5 gap I have now but am looking for something more in the middle of my 6.5 Creed and 300WM hunting rifles. The Tikka limits me to 3.4" so I'm worried about the rem mag running out of mag length and I feel a long throated SAUM or WSM should really shine here. I already have metal long action WSM mags so that's not an issue. Mainly I'm concerned about quality brass availability. There are only a few makes for either it seems, though I find more for the WSM than the SAUM. What are your thoughts on which 7mm for a Tikka? Thanks, Sam.
