Dave those velocities are FAST. I too would caution anyone from thinking that these are normal velocities achievable with a 7STW. 3600 fps with 140 grain bullets is a hot load, 3600 with a 168gr bullet is insanity. How long is your barrel? How many firings are you getting from your brass? What brass are you using?

The problem with factory loads is that the posted 3450 is like 20% below pressure signs. They load conservativly.
I have a 34 in Lilja 1:9 twist 4 groove.
The brass is rem, I dont know maybe 6 firings maybe more. I have never really counted but I dont worry to much about that as I bought 500 pieces.
If you do a search for lost river bullets I have a post on it where I go into detail over what grains of powder and what velocity was acheived.
If he worked up his loads I'm sure he could get 3500 to 3600. I used H-1000 for a lot of my stw loadings but I have switched to other powders. I think Re-22 was like the hottest and didnt get good accuracy out of it.
Its cool if he doesnt want to use my load suggestions, its a dangerous game loading and one should always work up loads even the ones suggested in the books.
I have seen more insane loadings on some of the other websites that I know are HOT loads. I dont get pressure signs with 74.5 grains of H-1000 and the Berger 180 grainers. I am pushing them at 3100 fps and am sure I could probably go to say 78 grains and be ok. I think I figured it up once in my gun that for every grain equals like 41 fps so maybe I could touch 3300 fps.
I have also been to Williamsport where fellas beat the bolt open and the primers fall out and the case is done and its bascially a one case rifle. Course they are doing some crazy stuff too, 3400 fps with 240 grain smk.

Dave a 34" barrel would certainly make a difference between a 26" factory barrel. My point was to ensure that no one reading this thread runs out and tries to get the velocity you are getting using an extra 10" of barrel.

I have never shot factory ammo in any of my guns but if it is like most factory ammo the actual velocity listed vs factory listed velocity is about 50-100fps slower. I have seen this in several guns from different ammo manufacturers. The guns were .22-.250, .260, .300 Win, and .300 Ultra. The 300 Win was Winchester loaded rounds and the rest was Rem. Is this scientific proof, no way, just my limited findings.

I do not think it is reasonable to expect 3500-3600 fps from a 140gr bullet using a 26" factory or custom barrel. I have loaded for 4 different 7STWs. Two have been custom jobs and the two others were factory.

In one of my my 7 STW's, I shoot 83.0g of R#22,
Win case ONLY, Fed 215, 140g Nos/Win Combined Tec bullet producing clover leaf groups that measures in the high .300.

This one heck of a bullet for big deer! My brother shot a 360lb white tail at 460 yards in Kansas dropping him right where he stood. He has since killed 12 deer with this combo, ranges from 50 yards to 375 yards.

I shoot 86.0g of R#22 in the Win case with the 120g Nos BT, and it flattens deer right where they are standing. I hope to try the Barnes Tripple shock with this load later on in the Spring.

Warning: Remm brass is very soft, use only Win cases in this cartridge.

Work up to these loads in your rifle, your rifles are different than mine!

Well your in luck then because my wife has a factory stw. It can be done and done safe as long as you watch for pressure signs. I load her 168 smk to 3400 fps.
But I do understand what your saying and yes people should nto expect to get the same velocites as others especially when they are talking an extra 10 inches of barrel. My wifes gun just happens to accept that velocity without pressure signs. He may not get good accuracy either, the fastest load may not be the most accurate. Although it seems that the Berger's and the SMK's enjoy as fast a speed as you can get with regards to accuracy.

My lilja barreled Mark Bansner built 26" STW will do 3550 w/140 and 86gr. of H1000, any more and I start to get ejector pin marks and slightly stiff bolt lift.
