These are totally worth it !!.... there are no cons to it !!!!! Do you load data/ladder test with out it on or on!!!! What ever you like or feel like...... once you find your pet load or sweet spot or what ever floats your boat!!!!! All your doing is finding the speed of your load .... hopefully you wrote down what you loaded up .......reload what you loaded or maybe you loaded a bunch of them ... shoot again and adjust your sight
Once again I love mine ... get what you need to down load on your iPhone or iPad or what ever ... it's totally worth it if you reload and do load development .... I love mine ....
Did I say I love mine
With the data you collect from it you can make your dope ..... or cheat sheet ..... it's worth it when you find that sweet load .... I did it for my .220 swift.....25-06 browning bar.... benelli .300 win mag.......it was fun and worth every cent!!!!!!!!!!!!!!!!!!
An Awsome Tool!!!!!!!!!!!!!!!!!!
