It sounds like the general consensus is that the SWFA is better than the PST but inferior to the Razor. Is it worth my time to save some more money and get the Razor? My main thing is that I don't want to have any regrets down the road when I do the rebarrel for a 260. I live and die by the principle of "buy once cry once." I would much rather justify the price than apologize for something less. Being that I'm in college, I don't get to shoot as often as I would like. It's much more important to me to have top notch equipment than to have a usable sub-par setup. I noticed in the recent "what the pros use" thread that not one contestant was using SWFA.
I realize this is old, but if you're not in a hurry, Brownell's usually does 10% off for Black Friday, plus you can sign up for ebates and use that to get a Razor for $1755 + shipping assuming they do the Black Gun Friday again. I know it's a ways off, but if you're saving anyway .....
or you can always buy a used one from sample list or here
Also, consider the fact you're asking these questions (not condescending, but mirroring my realization about 2 weeks ago). If I'm asking these questions, I prob can't pick these details out from one to the other. I just got my 2.5-10 FFP PST a couple weeks ago. That is the best scope I have to date. I can tell you that the quality is pretty darn good. I realize it's not in S&B territory, but I'll never have one side by side to look to make me realize that either.
I'm in the same boat for my .338 Lapua build. For me, the main deciding factor on an SS HD vs Viper PST is the travel. If the PST will get you there, I go that way realizing I'm giving up some optically, but for the difference I can get set up to re-load. As far as I'm concerned optically, there's only so much that matters. If one scope takes me from the 6 down to a 7 on the comp. chart, that's just not worth an extra $550 to me. Once I get to the point where I can see functionally well, I'm OK missing a minor detail. YMMV
I'm also not sold on the mil-quad reticle. That's why I'm going to "test drive" a 16x fixed power so I can see how it works for me.
