[QUOTE="johngibbs222, post: 2022633, member: 49619"] I use the magnetospeed sport. It's proved very reliable in use. I have a ruger #3 in 223 with a 22" barrel and a ruger #1 in 308 with a 26" barrel. POI shift is less than an inch on both and it doesn't appear to cause any spread of the groups so once I've checked out the velocities it's just a matter of taking it off and firing a 3 shot group with the chosen cartridge and redialling that back in, if necessary. The instructions say to use it on c/f rifles/guns only. I think what they mean to say is don't use cast boolits with it. Having said that, my 223 hard cast bullets with gas checks seem to trigger it OK. WTH is a McGyver solution? [/QUOTE]
