I have just recently purchased my first true LRH rifle through the classifieds on this web site. It is a rem 700 Sendero in 7STW. It came with Hollands rings and bases and I have have put a Nikon 5-20x44 w side focus on it. I would like to add an Angle Cosine Indicator and an Anti cant device to it. It seems like it would be better to go to a Pictanniny base to attach these items rather than hang them off the scope with additional rings. I was also considering a 20moa base rather than flat. In reality I will probably not shoot beyond 750 yards for now but I hope to eventually get to 1000yds if my abilities will allow it. I have taken several deer and elk at 500 yds. Any input would be appreciated. Thanks.
