Looking for someone with throat depth info.
Specific to Savage and Tikka 223s. This is reloading specific.
I have found that every rifle has a cartridge length it likes best. So I usually try to control the distance of the bullet to the rifling lands. Question is whether I can load to that length and STILL fit cartridges in the mag.
Anyone know their OAL where the bullet touches the lands on Tikka or Savage 12 in 223 rem? (name the bullet too of course). Or have you measured from the bolt face to the lands somehow?
Why? I had a Remington 700 in 308 that would shoot 1 3/4 inch groups. I tried and tried to build loads it would shoot. Nada. But then in frustration I took Remington factory 150s and pulled the bullets out to nearly touch the lands (2.85 OAL). (nothing shot better, so why not start with that?)
Groups came down to 0.75 without changing anything else, repeatably. That day I shot 0.68, 0.72, 0.78, 0.58 groups back to back. Then shot factory length again and got 1.59 I could hardly believe it, but data is data.
Since that time, I always watch the "bullet jump distance" which is how far the bullet travels before it hits the rifling. in 308s I found 5 or 6 guns that like 0.020, 0.010 or even sometimes 0. It works.
Factory rifle makers Remington, Weatherby use fairly long throats. They do this to manage peak pressures. I know nothing about Savage and Tikka.
So that's why I am asking if any reloaders know where their lands are relative to the bolt face. I am gonna get a 223 bolt gun and need a starting point, hopefully before I buy a rifle.
