Just starting out with my first LR Rifle. Can anyone provide good starting load, 300wm, 1-10 twist, 5r barrel. RL-22 powder, win mag primer, 208 A-Max. My loading book dosen't ever list 208gr, How much powder to start? How much will reach max loads? Thanks!! I can't tell you guys how much I've learned on this site, reading all the info!!!

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: magshooter</div><div class="ubbcode-body">I shoot 190 SMKs out of Lupua brass with 82.5 grains of H-1000 </div></div>

I will second this load as I run 82 grains in same setup.
 
Re: 300WM Help

I shoot 208s @69-71 gr.VHT 170 depending on the temp.on that day with Excellent results.
178s @ 72-73 gr of VHT 170 averaging sub. 1/2 min 5 shot groups.same for above loads out of my Surgeon Remedy 300 1-10 twist.
all loads shot @ approx. 85 deg. and 65% rel.hum.
Again, these are fairly moderate loads.depending where you are,you could up them up a bit. but i've only fired 100 rnds thru this rifle sofar.
 
Re: 300WM Help

Per JustPete's advice I wrote Hornady for a load on the 208 AMAX, using Retumbo in a .300WM. Unfortunately, they have not tested Retumbo.

Does anyone have load data for Retumbo? Please PM me. I'm using 208 AMAX, 27" barrel. I looked in the reloading archive but can't find anything. Hodgdon told me 85gr but I want to confirm.

Please advise.

Regards,

Re: 300WM Help

if you want to run retumbo with 208's just start with the min. load for the 200gr accubond and work up and you should find your sweet spot. I had the very same question and that was the answer I got.
