All my wildcats on the 300 & 338 Norma Mag (imp 35*) are on the Rem 700, Have 4 guns completed, one getting built and gonna do two more when reamers get here, all on chrome moly Rem 700 (300 RUM donors, bolt face opened up) McMillan stocks & Jewell triggers .
have not done any on the Win 70 (crf or pf)
There's a guy on LRH that has the case head turned down to RUM dimensions in order not to open bolt face and still be able to use 300 Norma Mag brass for his " 6.5 Osprey " wildcat on the 300 Norma Mag necked up & 35* shoulder, his wildcat has a few more grains capacity but has a short .255" neck .
my 6.5 PRO has a .347 " long neck and 105 gr h20 capacity
