I've ordered small batch of Norma GT in 223, 308, and 6.5CM few months ago to try out.
Put few rounds of 175gr 308 through my deer rifle after reconfirm zero with SP hunting ammo.
Got 2440~ ish ft/s from 18" 1:11 barrel with low SD. Did under 1 MOA at 200 with ease.
Like the ammo holder with...
Yes, 185gr. @ 1050~fps out of 1:11/ 18" barrel.
I had exact same questions you had in your earlier post. Waited for the opportunity and got the answers I was after.
As a reference for heavy 30 cal at subsonic velocity.
185gr. Winchester subsonic HP,
50yd hit through the neck, (entered behind lower jaw on left side/ exited behind the right ear)
Dropped on the spot, expired under 30 seconds. The soft-core did expend and exit wound was no less than Speer...
Happy owner of CTR (308 Win) and SS Varmint (223 Rem) here. If you'd like to test drive the CTR let me know.
The importer for Sako/ Tikka, Beretta USA, does not bring in all the models produced in Finland.
What can are you running? Most direct thread 5/8×24 requires minimum barrel diameter of 0.7", don't believe T3 light models come with thick enough barrel.
It's no longer produced in US. Imported from Russia, Eastern European countries, and China.
It'll dissolve caked on carbon off of aluminum head with 100k miles and make it look like new cast.
