Well compared to dope or drinking in the long run it's a less expensive addiction and my wife would much rather see a new rifle in the gun room or in the truck than pick up empty beer cans or toss out scotch bottles.

I currently own two including my all time favorite rifle which is a Model 70 Sharpshooter in 7mm STW. If I can get a couple of customers to pay up in the next week or so I'll have a third which will be a dedicated LR specialist model for long range ambush hunting.

Once you get to shooting the STW though and understanding what it's capable of given a good barrel and action they are truly amazing.

That is a nice way to do it. I'm doing the same thing except I'm using a 7 mag. With 139 grain bullets.

Re: 7mm STW Brotherhood - For those who shoot the 7mm Shooting Times Westerner

Looked up some load data on the Hodgdon website for the STW and noticed that they list their pressures in CUP instead of psi... I assume their CUP listings (around 52000) coincide to loads that are in the 63,000 psi range since the 7mm RUM loads are in the 63 ksi neighborhood and are all listed in psi. Guess their data for the STW is older and they were still testing with a crusher gun?? Would be nice if they would update their data since SAAMI max pressure is now listed in psi for the STW.

Makes me want to splurge for a strain gage setup so a guy will really know what his chosen bullet and powder are doing in there...

Loaded up about 60 accubond long range pills in 168 and 175 to do a bunch of testing with. Using mostly H1000. Loaded some retumbo also to see how that compares behind the 175s.

18 of them are my best load from my first round of testing. 75 g. H1000 with the 168's and 215 primers. Post results when I get time to send them down range.

Planning to employ the OCW method at 300 yards to hopefully find a sweet spot. If I don't find a consistent winner I will be looking to Hart or Rock Creek for a barrel.

FYI, found a pretty good answer on the CUP vs. PSI question I posed if anyone's interested. They do correlate well and can be converted with reasonable accuracy and of course discretion.

Good info to know...

I LOVE THIS CARTRIDGE!! 7 STW Rules!!! My rifle started out as a 7 mm Rem Mag Weatherby Vanguard which got rebarreled with a Douglas #6 26" 1-9 twist and it shoots like a house on fire!! Pet load is 150 gr. Nosler BT sitting on 80 gr. 7828 with a Federal 215 spk plug. Shoots flat as a pool table leaving at 3550 ft/sec.!
Knocked a whitetail down at 300 DRT. Wouldn't shoot anything else for long range hunting it really is the cat's meow!! Another load I like alot is 81 gr Retumbo pushing a 162 gr Hornady BTHP--Super accurate with very high BC!! Awesome high power 7mm cartridge!!

Pretty stout load there. I've ran a couple of 7stw rifles with 7828 and they were topped out by 80 grains 7828 with a 140 sierra. If you have a generous throat you may be alright, but your brass life isn't going to be great.
