4 Σεπ 2015 · A barrel with a 1:8 twist rate is quite versatile and should be able to shoot just about anything except perhaps very lightly jacketed and low mass varmint rounds, and tracer rounds. Basically anything from 55 grain (or a bit lighter) up to rounds with projectiles too long to fit into an AR magazine.
26 Απρ 2023 · I’ve picked up a Tikka T3X in .223 with a 1:8 twist barrel. Are there any bullets people would recommend to suit this? I’m trying to gain some knowledge here as to what type/weight bullet suits this barrel rather than say the other flavour 1:12 twist.

3 Φεβ 2023 · A couple of people on this thread using 40 gr bullets in fast twist (1:8 & 7.5) 22-250s, v-max in the 7.5 at 4150 fps. No bullet blow, the other is using the noslers. I personally have shot 30 gr cup and core bullets nudging 4000 fps in a 1:9 .223, no issues at all.
27 Ιουν 2011 · Optimum twist rate is misleading. A 1/8 will stabilize evrything up to 80 grain single loaded rounds used in highpower tournaments at the 600 yard line. Magazine fed rounds (77 grains and lighter) will all feed and group very well.
