7 Stw

My favorite load is 79.0 grains of RL 25 behind 160 grain TSX @ a chronied 3370. Recoil is nothing to worry about, especially given that you're generating about 3800 foot-pounds of energy at the muzzle, and accuracy is incredible. Zero'ed at 300 it drops just 7.5" at 400 yards.

I also have a hot RL 19 load for 140 grain Accubonds, that gets 'er up to 3450, but it's over 'list'. Very accurate, same ridiculously flat trajectory.

Excellent accuracy with most of my load development in this chambering, I'm usually spoiled rotten for choices.

Either you have a 36" bbl... or are running well into the red on that one... only 150fps faster than the 7 RUM:rockOn:

Nope - that is totally doable with 24 - 26 inches. The 7 STW in my opinion, and in my experience, is under rated in every manual that I have seen. I (and a couple buds) were consistantly getting 160's over 3300 and 140's (my favorite load for the STW) at about 3500 - both loads at safe pressure levels. My 140 load zero'd at 300 was only 18ish inches low at 500! I loved that rifle! The only down fall is that with all that powder you don't get very many shots before signifigant throat errosion.

7 STW, I used Nosler bullets, H1000 powder, Remingtom 8mm mag brass (necked down of course), and Fed 215 primers. Work up a to max and then back off a grain or so - seems to be where this caliber shoots best.
 
I've settled on WW brass CCI 250 primer and 77 grains of IMR 7828 under a 150 grain Nosler Part.Can sneak 78 grains without signs of pressure but accuracy drops off a tad.
No crony test as of yet but it's flat shooting and accurate and works well on large game.
 
I've owned several of these laser-flat shooting big 7mm's over the years, and always got the best results with the 160 grain Partition and a healthy dose (87-90gr) of H5010. In a 26" tube, this usually chronys around 3300, and is very effective on whatever you shoot with it. Regards, Eagleye.
 
I use a 100 gr HP Hornady with 85 gr H 1000 powder for a varmint load in my Ruger #1.It has a custom 29 in gain twist barrel on it.I don't have a chrony , but they are movin when they leave the barrel.Makes a big splat on rabbit size critters.

Most STW data in the manuals is junk. That 79.0 load of RL 25 came from Alliant, and it's far, far higher than anything I've seen published--yet still totally safe. It's too bad the manuals don't give this round more love, it's got LOTS more room than it's given credit for.

I'm getting my data from a factory 26" Winchester barrel, in a rechambered model 70. The barrel should last another few hundred rounds at this pressure level, but luckily it's easy to download the STW to 7 Rem Mag levels--and listed levels, not the 200 fps slower that they _usually_ shoot when they first meet a chrony...

I agree.My Hornady 154 Interbond load is 6 grains over their max from the newest manual without pressure to speak of.Settled on the 150 NP because it shoots better and the partition has never failed me.
