For me, I've never had it shoot exceptional in any of my rimfires. As stated already difference between this and Ultra Match, which I haven't seen available in a pretty good while now.
Yeah, I was confused. There's been so much discussion here recently about twist rates and special/different bullet shapes I thought you were talking about something special here.
I have tried the FGMM in several different rifles, Sako Quad with Lilja Match barrel, CZ452 Varmit, Remington 513T.
All three were duds with Federal Gold Metal Match in my rifles. I had better luck with Norma TAC, Norma Match, and Lapua Center X.
