Load data needed 300WM

[Karlandco]

Hello gentlemen,

I haven't made the leap to Quick Load yet but it's on the list. I have a 300 Win Mag that I'm forced to change bullets on due to lack of 210 VLD's availability. If anyone has data for the following I'd really appreciate it.

300 Winchester Magnum
208 Berger Hybrid
Reloder 23 & Reloder 26

There is a phone number listed to call for load data of bullets not listed.

Yes I may call next week. Thought I'd ask the forum for now.

Argh. I checked a couple manuals as well. No luck with 208 Hybrid and either RL powder you mentioned.

Use Hornady Data for 208gr ELDM

I have the Bergwr manual but am 7 hours from home. Sorry!

Didn't think to check there, thanks...but idk I'm getting 150fps faster with a heavier bullet than they show max for a 208. This is exactly why I'm going Quick Load...soon. thanks for the reply just the same.

No RL-23 in my manual but it's 1st addition 2012...guess I need to update the ole library

I can get you sims for the Fee GRTools.
What is the COAL?
Barrel length?
Case capacity if you have already measured it.

it should be same load, You may drop a grain, it could take a smidge more, is bearing surface on the hybird a tad more

I would really appreciate that information more so because it would be interesting. I have found so many accurate loads for this rifle that I'm having fun tuning it to smaller groups just to hone my reloading and shooting skills. I have over a year to wait for my f classer so this gun is going to be my petri dish so to speak. Regarding your questions:

-What Coal are you referring? Case or loaded round? If loaded.. Base to tip or CBTO? Into lands?

-Barrel length is 26". I'll need to measure exact.

-How would you prefer case volume? If you mean 90% alcohol weight, I can provide this. If other let me know.

Thanks for your time and please let me know your experience and opinion on GRT.

Base to tip for loaded ammo with 208 VLD beriger bullet
Case volume in gr of water, net.
26" would fine. if exact is available, it would be from bolt face to muzzle.

The published velocities in loading manuals mean absolutely nothing. The loads are there to give you a range to start with.
Find a starting load using the Hornady information, work up to where you want to be, or you see pressure signs. Easy-peasy
