Hi SWFA,
I am going to buy the SWFA SS 10x42 side focus MRAD scope ( Stock # - SS10x42MMQ ) . I want to put it on a Savage Model 10 FP .308 with a one piece Weaver base. I want the scoop as low as I can get it. Can I get the SWFA low rings? Or do I need to get medium rings? I don't want to play the return game. Can you help me SWFA? |

Unfortunately this is a very tough question to answer without having the rifle here. There are several comprehensive aspects when it comes to mounting that I evaluate.
Bolt and Action clearance? Objective bell clearance? Are we set up for a solid cheek weld? Is this going to give us adequate eye relief? Trying to do this over the phone or through email is nearly unfathomable, because not all manufactures follow the same guide lines in measuring or manufacturing…it’s something that I have to put on the bench and measure. I can tell you exactly what I measure to see if I have adequate linear clearance. First I will take my dial calipers and measure the outside diameter of the objective bell. For instance….take the SWFA SS 3-9x42, the outside diameter is 50mm. Then I will divide that number in half. [ 50mm x .5 = 25mm ] Then, and this part is critical, I will measure the rings. Several manufacturers measure from different places. Take Burris, Millet and Simmons. They measure from where the ring connects to the base to the valley or where the scope rests in the ring. (see figure B in the attachment.) Companies like TPS, Seekins, and Badger Ordinance measure, in my opinion correctly, they take their measurement from where the ring connects to the base to the centerline of the ring. (see figure A) 
Then I will take a measurement of how thick the base is. Seekins bases for my Remington 700 .243 WSSM are 9.81 mm. Now that I have those measurements. Rings =(lows[SEE3082L4] = 22.82m) Base = 9.81mm [22.82 +9.81 = 32.63mm] and then subtract from the outside diameter measurement. 32.63 minus 25 =7.63. Since the number is positive, you should have adequate linear clearance. If it was negative, the bell would be touching the barrel, which is what we do not want. I hope this helps. |
