Is .122" too much jump? Unsafe? 300 gr. Berger Hybrids .338 Lapua.

Berger tactical ammunition is what I am shooting, and it shoots really well, but is too long for magazine on my 98B. Want to load same bullet.

The jump itself is not unsafe. All load work up precautions apply.

When I first bought a .204R years ago with factory barrel.... the jump to lands was .187 and this thing
was very accurate. Loading them singly the closest I could get to the lands was .048 thousands. I
finally shot the barrel out and now it is a 20 practical with about a .010 thou jump.

A long jump does make one difference in the positive.......you can use more powder.
Within reason of course.

My comp rifles jump 215gr Berger’s .120” in most cases, my 264 jumps 140gr VLD’s .080”.
I find short throats and close seating beneficial in some cartridges and applications but not all.

Cheers.

Long jump is what I call free bore
If you ever shoot a Weatherby you would know .
I had mine rebarreld and took away the free bore and my Weatherby factory ammunition was way to hot .
Jumping a bullet take away the pressure
The initial start pressure
Setting back the bullet also decrease
The usable case capacity
