Hi, Can anyone give me load data for a 7MM STW 140 gr. bullet load with H-1000 powder??.....Thanks.............Big K

H-1000 From 69.8 grains to 85.5 grains
Federal 215 Primer

My buddy bought a rem 7 mag that was converted to 7 stw. It loves 82.0 H1000 under a 140 barnes xbt. This gun only had a 24" barrel and it only pushed them 3200 fps with this load (maybe the rechamber somehow cost some velocity) but it really really shoots and he's shot tons of carribou and a couple moose with the combo. Doesn't seem that the animal knows the difference.

Kraky, I did the same thing as your buddy back when the STW was a wildcat. I think the slower velocity has more to do with the 24" barrel then any rechambering goblins. The STW (like a lot of overbore cartridges) really needs a longer barrel to show it's stuff. That said, I've seen loads posted at velocities that plumb scared me. FWIW - Dan

I kind of doubt that H-1000 is the best powder for this application.

The 140 grain bullet is just a tad too heavy for IMR 7828, but it will do.

H-870 or AA 8700 would be better. My personal favorite in this caliber is surplus WC 872. If you try it, you will likely find it considerably slower than H-870 (which it is often compared to) and with a 140 grain bullet you may have to use a drop tube to get enough into the case -- but be careful as surplus powders DO vary in burning rate. One advantage this powder has is that you can get it for about $4 per pound.

Hodgdon Retumbo or one of the Vhitavorhi powders designed for the .50 BMG might be choices worth trying.

Actually I find that 7828 works best with 140gr bullets in both of my 7mmstw's.They produce 3500fps and average 1/2" groups.

Have to agree with Stumble, Imr7828--81-83grs max with 140gr bullet. WBY Accumark 26in barrel 3530-3550 av fps.H-1000 was 100 to 150 fps slower and less accurate in mine with H-1000 and 85-88grs max

i wasnt impressed with h 1000 with 140 grain pills. my load is 78 grains of r 22 and 140 grain barnes xxx. 3600fps out of my 28 inch shillen.

Thanks guys!....I am loading some hunting ammo for a friend and he brought a bag of 140 gr. bullets and a can of H-1000 to load for him so that is the powder I'm stuck with. I just didn't have any data on this powder......Myself, I sold my STW a while back...I now have a 7MM RUM which I like......Big K

Bigk-I have two 7mmstw's and a 7mmultramag.I prefer the stw's.The 7mm ultramag only produces about 50fps more than the 7mmstw's for a lot more powder and reduced barrel life.I do however like my two 300ultramags.The .308 bore seems to be able to take better advantage of the ultramag case.

Since we have wondered off the subject-- the7 U-Mag another one of the biggest jokes of remington that they made. Even though they started loading for the 7 STW first, they never would load it to it full potenial when there was already data out there for 3500fps with the 140 gr bullets. Many people have traded in for the 7 STW and got rid of there 7 U-mags cause of the more powder used, most could not top the more than over bore cal. than with the STW and could not get the accuracy or fps with the 7 u-mag. I still have the article when Bryce Towsley of American Rifle Feb-2001, wrote that the 7u-mag verse the 7stw would get 200fps faster than the 7 STW. He stated that the 7u-mag-140 nosler at 3466fps and 7 STW at 3266 fps. Probably got a good Rebate from Remington For spreading Such Bull {{SHIT}}Shooting my 7mm mag using the 139gr Interlock Hornady Bullet with data from Hornady Loading Book Vol #2 1972, That today they have knocked down the load a few grs, which Had a load for 7mag-139gr -H-4831--High 71.3-3400fps//Med-69.8 3300fps which I have used for 32yrs-69.8grs and Have to my collection after 4 different guns all having 24 inch barrels except one-first gun-110 Sav, Ruger, a Wby VGX and a Sav-Heavy Barreled 26in sst-syn which when my wife did not want to go elk hunting any more, sold it to my friend and got my 7stw in a Wby Accumark. All 4 guns shot 1in or better groups and had an av-2990-3310fps and 3330fps with the 26in Savage. 14 elk and countless deer with this load. Even people besides Layne Simpson, wanted to know when remington started loading the 7stw and Why the loads were not up to spec.?? Of course we all know that they were working on there own little project. Another gun writer that I need to where HIP-BOOTS around, to change the main subject {{ even more }}
