[QUOTE="baldhunter, post: 2756645, member: 11853"] I used Tubb's on a few rifles.They do help sometimes.They can move your throat forward.I too experienced about a 100fps velocity drop on a 300WSM.That rifle had zero freebore and I had to use 180gr load data for 165gr bullets.I was getting max velocity with less powder.After using 20 of the Tubb's bullets it gave me about .010 freebore and for the first time I could use the 165gr and 180gr data.I had to bump my loads up about 1.5grs or so depending on the powder,to get back to the velocity I was getting before.I used only 5 in my Ruger 1,to go from an 1.25-1.5" shooter to .5-.75"shooter.A couple of other rifle I did 25 of the Final Finish in and they shot way better than before.A 300 Win Mag I had was never that accurate.I shot this 200yd group after shooting all 50 of the Final Finish [url=https://postimg.cc/rdvyHBnh][img]https://i.postimg.cc/SsKXnqWp/200-YD-GROUP-002.jpg[/img][/url] This is the before and after photos on the 300WSM after 20 bullets.You can tell the difference.
