7mm STW Reloading Thread

[Clovis Man]

70-71gr of 7828 SSC

Thanks for that info, but unfortunately powder is about impossible to find here in town, and I have a little bit of Retumbo left, so want to try that first.

Research continues...

Thats because of the 24 inch tube ..... Do you have any 140 Combined Technology's on hand?

No, but I do have some 140 Ballistic Tips

I just loaded 73-75.4 gr retumbo by .4 with 180 gr bergers at 3.612 per Bean and I'll let you know how it shoots. It's a win 70 with 28 inch bartlein. We will we Monday.

Well -- Seymour it is, I guess. You ever drive over to the Ponderosa in Dickens for their brisket?

No but I have stopped by there a few times on my way to Lubbock.

I grew up in Farwell and spent a lot of time driving back and forth between Farwell and Throckmorton in my youth so we got lots of chances. My dad seemed to get a speeding ticket every time he drove through Haskall County so we usually took the northern Route instead of taking 380 to Post and turning up 84.

Now for a serious question.

I've been using 80 grains of Retumbo and Sierra 160 grain spitzer boat tails in my Model 70.

I recently scored a box of Berger VLD hunting bullets, 180 grain. Somebody said 74 grains of Retumbo behind that bullet -- but is that a minimum or a maximum load?

And -- how do I determine the COAL? I mean, these bullets are LONG. I guess I could simply seat one pretty long in an empty case, and then chamber it, with the idea that I would find the dimension to the rifling. Somehow this seems a bit "iffy", especially if the rifling grabs the bullet and pulls it out of the case.

Somebody give me a clue here, because it's warm enough for me to go out in the garage and start pulling that lever!

If you want to have a repeater just load them to the length of your magazine measuring tip to base.

Call Sharp SHooter Supply in Lubbock and see what they have on hand. They keep a pretty good supply and get regular shipments.

That's a thought. That's a GOOD thought. Guess I'll do that later today.

Load some of those in the same step up ups as you did the Barnes and lets see what happens

Let me know if you're going to head down that way. I have to go pick up a gun there before they decide I donated it, HA!

You know I'll be calling first, that's a hundred miles each way!

Ok, will do. I won't be able to get to the range until the end of next week, so I'll send you the results then. Thanks again for your help

So I called them. No Retumbo in stock. Now I'm researching to see what else might work. Maybe RL-22?????

If you can't love the one you want, you have to love the one you're with.
Headed to Lubbock for some RL-22.

I would use 7828 before RL22. 7828 is only 1 notch above RL25 on the burn chart, so it's slower than 22, for the heavier bullets.

I can't believe you can't find 7828 or 7828 SSC.... Even during the great powder drought of 2012-2014, I was able to find 2 powders... Hodgdon LeverEvolution and IMR 7828 SSC. That's why I swapped pretty much everything to loads with 7828 SSC...Because I can always find it at my LGS.
