alf, that's good news. I have never shot over one but it seems a lot of people consider them to be the standard. I was at the range yesterday and ran into an old timer who has a model 35. He actually said he liked my older Pact and that he never used his because it's too much work to set up. Would love to shoot over it though to try it out.
I started out with a Chrony then moved up to a Oehler35P.
The Oehler is top quality and has a 3rd skyscreen so you get each shot velocity read twice, thus eliminating most bad readings.
If you have a problem Ken Oehler himself will answer your questions
