308 Win Ladder Results

[DoubleGobble00]

Below are the results from a 250 yard ladder test. I really need more yardage but the shots and velocities are helpful.

308 Win
180 Berger
Lapua Brass new
210M
Varget
Seated to max mag length
250 yards

what power scopes on both ?
as usual low looks good
i am at a mere 2585 with 185's but .34 for 3 shots at 100

 

[ar10ar15man]

hunting rifles or target rifles ?
distance you are planning to shoot ?

Need to redue the test at 400. 250 is pretty close, but 43.5 looks good

Seated to max mag length

Why?

 

[DoubleGobble00]

This is a hunting rifle. It's a stock savage 10 in McMillan A3 stock. I don't want it to be a single shot, so I started at max mag length.

I'll shoot this gun a at target out to 800 yards but wouldn't plan to hunt with it past 500. I'll use my big guns for hunting long range.

I do wish I could have shot out to 400 today. Everything is too wet and grown up to get that far right now.

Have you tried imr4064? I'm getting single digit es at 2825fps with 168grain btsp in a cz550 varmint. Groups are pretty good also!

42gr is your load.
Look how wide your node is. 41-43gr grouped together.
If ur wanting more velocity I would test 42gr and 44gr and see what you come up with

This is the results I got from my 700 Remington 5R using the 168 Vld Berger bullet and IMR 4895

7 shot string.

 

[ar10ar15man]

he asked for ladder help.
he did not ask for bullet or powder choices
he is not shooting a 168 berger
he is not shooting 4895
so why post it ??

I wonder if the 45 + grain loads will get warm on fire formed brass I am getting ready to try pretty much the same thing except with win brass and at roughly 2.960 base to tip this length keeps the bearing above the neck shoulder junction and fits the mag pretty sweet in theory

What makes you think 'max mag length' is anywhere near best seated depth. It could be the very worst, as your ladder looks horrible.

Consider performing Berger's full seating testing before further ladder testing. Could put you on a better path.

Agree completely. The result you found is EXACTLY what a ladder test is supposed to prove out.
