7mm STW Reloading Thread

What velocity are you getting?

That's using remington brass.

This is with Peterson brass. I had to drop the load down almost a full grain to match the same velocity.

Hey everyone, I knew to this forum but not to the stw. I load/tested most of the hammer bullets for my custom remington 700 1-8 26". My most "***-kickin" load is the 160gr Shock Hammer with 77.5gr of H1000 to achieve 3350 fps from my 1-8 26".
Thats smoking along. What's the MOA on that load?
 
About something like this for 6 shots:

Im taking notes to try my first hand loads with my father in law. This is all new to new so im really trying to get it right the first time and not have to shoot alot to get good results. Im not sure what pulls I'm going to shoot I'm going to go out today and look for some. My gun lives 160's AB's. It's key holes them so I'm starting with that. I just need to find dies.

Yes, my stw loves the 160gr Accubonds, but I can never find them. I run them around 3250fps just like the factory nosler ammo. I assume you mean that they shoot well and do NOT key hole.
 
My STW (Remington Sendero) is being rebarrelled with a 1-8 twist 24 inch bull barrel, with radial break, cross-fluted, bolt trued. Bedding and pillaring work already done. Also is to be hand lapped. Hart Barrels is doing the work.
The original, purchased in 1995, performed well, .25 MOA groups but after nearly a thousand rounds, not so well now. I hope to get that back again with 162 grain ELD Xs, H1000, 3050fps.
 
Here is a follow-up with testing WC860 and WC872 in the STW:

Custom Remington 700 26" 1-8 twist
Arken EPL4 4-16 MOA
Fireformed Hornady 375 H&H 1x
Winchester Large Rifle primers

7mm STW WC860 Load Testing w_ 154gr SP.png


WC860 never showed any pressure, even with a moderately compressed load, but I stopped testing WC872 at 92.0gr because I got a very tiny ejector mark, bolt lift was normal, brass is gtg (also look at the velocity on that sucker!). As we can see, WC872 is significantly faster than WC860, or at least the lots I have, do not take this for gospel. So, moving forward, I will treat WC860 as a slightly slower version of the commercial H50BMG and WC860 as the ancient AA8700. If anything, the WC860 behaved exactly how my Lyman 48th Edition lists AA8700. Happy shooting!

Thanks for the follow-up. Still waiting for Hart to complete the rebarreling process. It may take another 3 or 4 months they say. I had previously been using 162 grain eldx but I may give 175s a try. Doubtful that I will have it back for the Utah elk season. My 300 Weatherby is my backup. Having good luck with 212s so far with the 300.

That 872 is walking the dog son. Have you tried RL25. Although, that's stellar velocity. How was/ is grouping? Nice load work up. This round is sooo responsive, and easy to load for. Great job.😃💡

I was not really shooting a group, I had my buddy just shoot them across the chrono to save my shoulder for my 7mm RUM. These 154gr SPs that I have a lot of were given to me by an older buddy who got me into reloading, but I use them to fireform my brass STW, 280AI, etc. The purpose of these velocity tests were to find similarities with published load data and work up from there. I did not want to waste my hammer bullets just fartin them over the chrono. I will use the WC872 for my hammer loads in the future, stay tuned for that!

I would really like to see how the H50bmg does with the same bullets.
