I have a rws-34 in .22 sighted dead nuts at 30 feet at 4x fixed. Im elevating my shot 20 ft up and out to 35 yrds. In other words ill now be shooting down and out to my back fence from my bathroom window. DO I HOLD UNDER on my mildots or right on for the added distance? Thanks! _________________ TFR   Posted: Tue Mar 16, 2010 10:34 am rsterne Moderator Joined: 15 Jan 2008 Posts: 2998 Location: Coalmont, BC Without a velocity and pellet type this is impossible to answer accurately.... I assumed 800 fps and a BC of 0.020 and found that for a rifle sighted in at 10 yards the POI at 35 yards would be about 0.86" high.... The effect of a 20' change in height at that range is minimal.... its only about 11 degrees, which raises the POI an additional 0.1".... If your velocity or BC is lower, so would be your POI.... and vice versa.... Bob _________________ Dominion Marksman Silver Shield - 5890 x 6000 in 1976, and downhill ever since!

I know this is basic shooting and I could just sight in at the exact spot.dont want change indoor setting. _________________ TFR   Posted: Tue Mar 16, 2010 1:05 pm Lipoly Veteran Member Joined: 06 Dec 2009 Posts: 241 Location: St. Louis, MO, USA If its the 21.1gr Kodiaks, I'd guess you are in the 550-600fps ballpark _________________ Philip RWS 350 .22 w/Leapers 4-16x50 Crossman 1377   Posted: Tue Mar 16, 2010 6:45 pm rsterne Moderator Joined: 15 Jan 2008 Posts: 2998 Location: Coalmont, BC Straight Shooters reported 660 fps with 21 gr. Kodiaks in an RWS-350.... Plugging in that, and a BC of 0.032 gives 0.2" low at 35 yards, and only 0.1" low with the height change taken into account.... basically dead on....

Bob He is using an RWS 34 though...350 mag having roughly 25% more fps than a 34...475fps @ straight shooters w/kodiaks. _________________ Philip RWS 350 .22 w/Leapers 4-16x50 Crossman 1377   Posted: Tue Mar 16, 2010 8:34 pm rsterne Moderator Joined: 15 Jan 2008 Posts: 2998 Location: Coalmont, BC WHOOPS !!!.... I misread, I thought it was a 350.... The numbers for an RWS-34 sighted in at 10 yards (Kodiaks @ 475 fps, BC = 0.032) are: At 35 yards: POI 3.86" low At 35 yards and 11* angle: POI 3.68" low Bob _________________ Dominion Marksman Silver Shield - 5890 x 6000 in 1976, and downhill ever since!
