Thread: 284 questions

Quick question for you 284 users, What sort of col you using with the 162's amax/eldm?
Putting some dummy rounds together to send away to the smith for throat length and just wondering what length is practical. Will be throating it for the 162 eld-m.

Is on a tikka with LA bolt and mag so can load right out.

Also, if anyone has 3 spare cases they want to part with for dummy rounds that would be much appreciated.
Can repay in 6.5x55, 7mm08, or high fives

Cheers
Nick

Make a dummy round about 0.5-0.75 mm shorter than the mag, assuming there is enough bearing surface left inside the neck

My 284 (Wby Mk V ultralights) I'm running COAL at 3.100 or there abouts with 160 TMKs and 154SSTs.
This is good for concentricity

Ya lost me there.
How does length or bullet choice influence concentricity?

If u seat the pill too far out there is insufficient bearing surface retained in the neck, especially with a boat tail pill like AMAX.
Leads to increased risk of misalignment & poor concentricity

This info. is gold for me as I have a short action winchester with modded mag length at 3.100. Going to start with some 140's

I run mine with 162 Amax still, OAL is 3.190. Fits the LA T3 mag really well. Mine only has a 17" barrel, its shoots very well out to 600 odd yards.

Awesome cheers man, yeah the barrel is at 18. Actually does all good with 140 nbts at 2700, but they do get blown around a bit, if I can launch the 162 at a similar speed should be a good step up i wind bucking ability w8th a bit of extra grunt

I'm at 2700 with 162gr from 17" so you should be sweet.
