Thread: Barnes seating depth

Think velocity rather than distance.the faster they going the better/ further they expand. Look at the graduated photos and from my experience they about right.

I reckon you need about 2400fps impact V

So you are probably talking under 200 yards.

No, the trick is to use the first (this bullet only has one) drive band as your seating depth/crimp ring/cannelure.



Don't bother playing with seating depth, load up powder charges until you find pressure. If the accuracy is not there, either you barrel twist is too slow or try another powder/more neck tension.

All factory ammo is made to a spec of seating depth, yet it suits the majority of firearms (if the ammo is good and firearm in spec).

Don't burn components needlessly.

Mostly 2 hundy because head and neck shooting. I think the 53gr beats the 55gr. Fired up with BM2 they really tag deer very well. Becomes a confidence thing after a while. They are an amazing pill. Yet currently loading 300 55gr GMK for my mate up the Raukumaras. Funny because I loaded 3 hundy triple deuce for him last month. Same pill.

I dont agree with this at all either for Barnes or Hammers. Both to the top cannelure. The monos love a tight long grip. They hold, the pressure hits the right node and banger they zip away.2C.

I tried some ttsx in a 270wsm with a super long throat and couldn’t get anywhere near the lands. From memory ended up nearly .200 off and it still shot under an inch. Seating depth wasn’t that critical on that one.
