The 177 grain 30 caliber GS HV hunting bullet is either .638 or .648 bc. On their website under hv hunting bullet technical data. The 300 wsm will push it over 3100 fps in the t3 light. With that bullet the 300 wsm becomes an excellent round. The 300 ultramag becomes awesome pushing it close to 3500 fps. The bullet is a solid copper allow that is similar in performance to the barnes bullet but doesn't open up quite as well. It stays together through about anything you can shoot it through hunting wise anyway. With the animals your hunting and the range your looking at your 300 wsm tikka t3 will be excellent and I see no need spending the money changing it up. Others probably have other opinions though. If you have accuracy problems with it many times changing the recoil lug system on it to one similar to the rem 700 and bedding it can help.
I'm looking at the GS website and the 168 .308 bullet is the heaviest one they have a BC listed for. The BC of the 168 is .433 at 3200fps. I don't see how adding 9 gr to a bullet will kick up the BC to over .6. Am I missing something or looking at the wrong bullet? They do have a 197 gr tactical .308 bullet that has a BC of .824 at 3300fps. That's impressive IF it can be pushed that fast accurately. They also don't recommend the tactical bullets for hunting.
I had my 7SAUM built last year and have nothing but good things to say about it. My best group (so far) was 1 3/8" at 600 yds. I'm currently waiting to order some 180 gr JLK bullets (.735 BC), going to H1000 or 8435sc, and a calm day to stretch it out to 1K. In good conditions this combo will be excellent at any range you feel comfortable taking a shot. Is there a reason you don't want to hunt with a muzzle brake? My wife and I filled 7 tags with the 7SAUM (with a CSR brake) and had no problems. However,we did have plenty of time to put in ear plugs. It's a beautiful thing to see your bullet crush a deer or antelope at 400 yds. PICS
and MORE PICS
I went with a brake because I knew my wife would be shooting it also and to be able to spot my own shot for corrections (I can see impacts after 300 yds or so). If you are wanting to shoot high BC bullets you have 2 main calibers to choose from: 7mm and .338. It all depends on how big you want to go. I know I can kill anything on this continent with my 7 SAUM.
