Action Viper Predator $695 fits rem SA pattern stock. comes tighter and cheaper than trued Rem but not quite to BR standards. Cannot buy and true a Rem for that cost. Rem bottom metal fits. With that action out now, not cost effective to buy and then true a rem SA. Long action due out in couple months.
Stock rem trigger off ebay or any smith for $35, add $25-50 for 2.5 lbs trigger job
Barrel- Broughton 5c or Krieger #4-7 contour depending on weight you want. 26" to max 28" cost with chambering $450
High tech has 20 oz standard pattern stock with cheekpiece.
$225 from brownells, note seveal others are in same price and weight range from Brownells.
Any wood laminated stock ($225-300, plus inletting and finishing which could be $150-400) will be 3 lbs finished, unless you have the barrel channel and butt hollowed out. At least glass bed or pillar bed $65-150
this gives you a 7-8 lb gun w/o scope. Great for carry, but hard on target range all day. Pick the heavier contours and lamininated or solid glass stock and you are in the 10 lb range at least. your call.
You could find a used Rem sendaro or PSS stock for under $150-175. Just skim bed it.
Would suggest Mark King or Bruce Baer in PA. Both are avid LR hunters, top 10 1k shooters and top smiths in the US. Go to www.6mmbr.com
and look at recommended gunsmith section.
you can go for as little as $1000-3000, your call.
$1000 option, Rem SPS in 300 WSM (max $440)
Lap lugs, recrown, firelap, adjust trigger ($200)
New stock and bed can be had for as little as $400
Scopes, hmmm you said target shooting to 1000 so that means target knobs. Nikon 6-18 ($300), leupolds 4-14 ($500) or 6-20 ($600), Zeiss conquest $700) is another.
Use burris signature rings with 20 MOA inserts to give you the MOA to 1k and keep crosshairs centered.
