Thread: Varmint rifle for about that 350m max range?

What they do is slow down faster than anything else. They are only flat over a similar or shorter distance than a high BC projectile.

Using the 270 as an example.

85gn@ 3800FPS, 1Okt full wind factor. 100yd zero. Drop/drift at 300 is -5.5", 4.25 impact energy 1840 FPE
130gn@ 3100 same same, -10", 5.75", 1833 FPE.

Maths. get it in ya.

He's says "a 130grn" then says "math get it in ya".

Your 130grn must suck based on the velocity retention. But let's run with it.

You developed a whole separate load with all that shagging round and you are giving your barrel a spectacular raping.

For 1" of windage and 5" of drop.

When you could just put a suppressor on and get really good with your 130grn load.
