I wish to give Scott Satterlee's 10 shot load development a try and already have a Cawldwell Presision premium chronograph and although I have enjoyed very good success with it shooting rifles and compound bows through it, admittedly it has been some what limited in use of under 100 rifle rounds so far not enough to IMHO prove it as highly reliable.To date with my limited use I had no issues getting consistent results and the free smart phone app is great. I was considering selling it as I can easily get $110 for my unit and put it towards a Magnetospeed Sport model for $149-$159. I have been researching both the pros and cons of the Magnetospeed and the Caldwell chrono systems and are concerned about the Magnetospeed's added weight on my barrel giving me problems that might seriously affect my velocity based load development rendering it unusable. Unless the several dozen reviews I read were all wrong, it seams to be well documented that the MS system will almost certainly affect your groups POI, usually high, but will the MS system have a large enough impact on my velocities that i can not use it for the Scott Satterlee load development system? The SC LDS as most know looks for a velocity based accuracy node in a 10 shot string of loadings varying .2 grains of powder from max going down. So if I'm understand the Scott Satterlee's system you are only looking for a velocity plateau where the velocity evens out and at this point pay no attention to group size, you can but at this point it's not necessary. Lastly I'm just beginning my journey into longer range shooting and are on a limited budget, and I belong to a private range and setting up and adjusting my Caldwell is never an issue and if i need i habve a awesome 10'x10' pop up canopy that i can set up in 10 minuets that I can use to shade my Caldwell if sunlight gets to be to much, and please don't suggest the Labradar as no way can i justify let alone afford it. So is the Magnetospeed 100% compatable with the Scott Satterlee 10 shot load development system? or should I just stay with my Caldwell? Thanks, Art.
