Firweed1969,
With everything I've read so far, NEF does lighten the triggers for free when you send a reciever in for a barrel fit. My Huntsman is producing 2 out of 3 rounds touching at 100 meters using 60gr. of Triple 7 and a 460gr. " no excuses " lead bullet, thats with a spit dampen patch run through the bore after each shot. I started with 80gr. and reduced by ten after a 3 shot group, my first 3 round group was printing 5 inches, 70gr. netted the same results, 60gr. worked great ! Good luck, glad to hear you are involving your children. :grin:
