These are good questions to ask since it will have a bearing on how much more work is involved such as opening the rails for a BDL and adjusting the feed ramp. If you use DBM there isn't any additional work except maybe some on the feed ramp.Should be "doable". Extractor mods, because of the larger size of the SAUM. Is your plan to feed it in BDL style or with magazines?
Ouch!I talked to Stiller about this on a LA, not that it should matter, with a standard bolt face that I was considering having opened up to mag bolt face and they told me it was a no go and it would cost $500 for a new bolt. I didn't see it as being cost effective so I left it alone and used a Rem 700 LA with mag bolt face that I already had.
This is what I was thinking. I'm thinking of doing the same with my Vanguard.Any time the 'plan' is to take a receiver that's set-up to handle standard, non-magnum cartridges and convert it to a magnum, these are questions worth asking. The interdnet makes it sound 'easy'. It can be damned time consuming! You need a good understanding of the feed cycle before ever beginning. A quick look at the instructions that come with Badger M-16 style extractor says the cuts are the same for .473 as they are for .532. Just the extractor is different. Both are made over sized and require 'fitting'.
Nightforce has great tracking capabilities, they are rugged, a bunch of elevation, holds zero forever, and reticles are designed for long range shooting. So if you are looking to shoot long distances constantly, then you need a scope that can take the abuse. -- gilmillan1
Nightforce is such a solid combo of reticle, available elevation, glass that is good enough to shoot at the longest range you can dial. Nightforce has bullet proof construction that can handle the incidental horse rolling or some other rodeo action. -- bigngreen
The total package. Nightforce is the best I have used as far as turret feel and solid detents. I have never had one that didn't track right on and always return to zero. Nightforce NXS is the best value for everything I need. -- Broz
