So would you recommend starting @ 76.0 of H1000 or start lower?

I have been told you are the Isaac Newton of the heavy STW's, and that you have it down to a science. So, any help will be appreciated.
Rl-19 is definately too fast for this Bullet cartridge combo.

You can use RL-22. Your max load is 70.3g will a 89.7% Case fill ratio. So drop about 5% and then work up in your rifle.

With H1000 76g is the Max indicated by Quickload with a fill ratio of 96.7% so drop about 5% and work up.

RL-25, Ramshot Magnum, And Retumbo have higher case fill ratios and seem to be better choices over all for this combo. But seeing as you have RL-22 and H1000, I'd try the H1000 First and Then RL-22 as a scond choice.

I tried H1000 in my rifle and it shot ok, but Retumbo was much better. I could only get 1" groups with it. Not bad, but My expectations were much higher than 1" at 100yds.

Again seating depth may prove to be a critical thing for your rifle. This is why I just buy a full box and plan on burning alot of powder to mess with all the possiblilities. When working up loads for Berger VLDs I first will make up test loads in .5g increments working backwards from the max, usually 5 rounds of each powder charge. I will Seat the bullets into the lands (using a dummy round) and then adjust my seating die to that length and then seat them deaper one more turn deaper on the seating stem. This will get them about .010-.015 off the lands. Then I shoot for accuracy. Pick the best shooter and then play with the seating septh abit more to see if I can tighten up the group.

PM me you E-mail and I will forward an e-mail that Walt Berger sent me some time back listing data for the 180g Berger VLD.

Hope this helps,

Dan

I'm using 73 gr RL25, .025" jump, with 180 bergers in my Rem 700 stw. Better grouping than RL 22 or Retumbo for me.

Good stuff Dano, I'm gonna look for that little pack you talked about. It's all one bullet series right? The other way is to buy 100, weight sort, choose the closest and tr 20-25. At that point you'll know, put the rest up for sale here and go on. Or just hold on and use for trigger time if you run out. It's always possible that as the barrel changes through it's life they may work down the road or can be used for easier shots under 300.

It's a shame I can't find any 25 around here since the great weapons scare of 2013 has happened.....

Can't find hardly any powder other than 17 & 19, can't even find any Varget hardly. Glad I got a few lbs of that stocked up. Wish all this scare BS would be over so I can go back to reloading like normal.

If I can't get these 12 shooting good, I'm gonna buy another 12 to try again. Then once I get those down, I'm gonna pick up a whole box of them (100) and have some fun.
