That said, besides form factor and what we can fit it in the .22 TCM has some interesting capabilities the hornet will never have like PDW applications for one. Heavier bullets at higher velocities than the 5.7 FN could ever dream of... the PDW side of the TCM is only beginning to be scratched now.
Short and fat for it's length case with a decent shoulder angle....we seen that formula work real well in other cartridges like PPC and Grendel for two examples. Somebody needs to wring this thing out as far as it's accuracy potential can go.
I have said elsewhere the TCM is a kind of 22 Hornet for the 21st century but that's wrong 'cause it's more than that.
I also have the MGM 24" Encore barrel. Mine has a 1:14 twist. What twist rate did you get?
I have found that the factory ammo and my reloads with the Armscor bullet are not that accurate (100 yrds). The main reason I decided on the Encore barrel rather than the RIA rifle was the ability to shoot a wider range of bullets and possibly a little heavier. Based on the stories on this forum about the RIA rifle I sure am glad I got the Encore barrel. I've not tried a lot of bullets yet, but I have used the Varmageddon 40 grain and it is very accurate (1/2' ten shot groups at 100 yrds). I'm using AA1680 which is also my favorite Hornet powder. I have some 40 grain VMax loaded, ready to try but haven't had an opportunity to shoot them yet.
I have shot some of my 37 and 44 grain cast bullets through the rifle. The accuracy of the cast bullet and the Armscor bullet seems OK out to about 60 yrds.
What have you tried?
What twist rate is everyone running in their Encore MGM barrel?
