Bountyhunter, I was going to build the exact same 300 WSM to shoot the 125grn Ballistic Tip. I talked to Richard Franklin about his 300 WSM project. It is an awesome varmint set up. Richards claims the 300 WSM will shoot the 125 Ballistic Tip at 4000fps, however, other gunsmiths on this sit said there is no way it can push the 125grn BT at 4000fps. The other smiths said the 300 WSM will push the 125grn BT at around 3700 to 3800fps.
After doing a little more research, and taking the advice from others on this site, I decided to go with 6x284 instead. The 6x284 will shoot the 87grn V-Max (BC .400) at 3730fps. This bullet and cartridge combination ends up being a better long range varmint set up than the 300 WSM with the 125grn Ballistic tip. The 6x284 will also shoot the 105grn Lapua Scenar (.530 BC) at 3500fps. Plus the 6x284 has less recoil and the 6mm's have a much better bullet selection.
However, the 300 WSM, with the 125grn Ballistic tip, is an awesome varmint set up. I have one of Richards videos and it shows what the 300 WSM can do to a groundhog, it's pretty impressive. But, the 6x284 is still the ultimate long range varmint caliber when you consider velocity, accuracy, recoil, bullet selection. Sure, there is better long range calibers, however, when it comes to pure varmint hunting the 6x284 is king.
other gunsmiths on this sit said there is no way it can push the 125grn BT at 4000fps. The other smiths said the 300 WSM will push the 125grn BT at around 3700 to 3800fps.
Pretty sure some of their ancestors said the world was flat too!!
For sure the 6-284 will go 3730 with 87s OR 3500 with 105s but not normally the same twist barrel.
The 6-284 is a known barrel burner, that there is no question on. The 300 WSM for some reason is not a barrel burner particularily compared to other magnums. We have guys right now in the 1k BR game shooting barrels in 300 WSM with 3300 rounds threw them in the 1k BR game, and the gun is still winning. Guess I am not a fan of a barrel burner cartridge. If you are happy with 800-1000 rounds for a barrel, great, I know those gunsmiths are!
If Richard Franklin says the 300 WSM like he sets up will do 4000, then I would not want to bet against him, regardless of who says what here. My bet is that they have not tried a 300 WSM with a 15 twist barrel, so that means that at best they were only guessing.
Most people and most gunsmiths say that a 300 WSM will not run a 210 over 2900 fps, but I know that it will run them up to 3050 also with the right set up and not be overpressure for that setup.
Guess I would not be worried about recoil in a LR varmint gun shooting those weight bullets in that weight guns, but a $500-600 barrel every yr or less does concern me. However, each to their own and those are the considerations that all of us have to make and what is important to each.

I have spent the last six months asking myself the same question. Here is what I came up with. Or should I say this is what I am in the middle of putting together right now.
I purchased a LH Remington 700VSF in 22-250. I then purchased a 28" Krieger barrel. I am having the action blue-printed. I am also having a Vias port put on the barrel. The twist is 1 in 8 to shoot the 75 grain A-Max.
The scope will be an IOR straight 16X scope. From what I have been able to find out this scope is the best tracking scope you can buy for under $900. If you come across a better one let me know!! Tom.
Hi in the last 12 months we have built 10 6x47 Lapua's 8 were target rifles the other 2 dedicated long range hunters. the target shooters are using 107gr Sierra's and hunters 105gr A Max's. they have a great barrel life with plenty off energy to take ferals past 1000 yards. we are building the hunters wiyh Rem Sendaro profile Lawton 8 twist barrels and they just shoot.
I believe it has the best balance between retained bullet energy, light recoil and barrel life. The 6x47 lapua is now starting to gain a large acceptance in long range shooting and it equils factory 243Win ballistics with better barrel life and accuracy as well as flat enough for the job at hand.
You can make anything feasable like a large allen mag that shoots so flat it seams wrong but the rifle must be practable not excessive in recoil, barrel life or noise.
If you want any more detail PM me I'm in Bendigo Victoria
In my younger days, everything I shot had to be the high speed get-it-all. It was fun to be fast but it came at a price. Short barrel life. If you want to go fast, you are going to have to pay for it. I've found out you can't miss fast enough? Out to about 700yds to 800yds, I've been looking at and building the 6mm BR with the 1-8" twist for the 105gr Amax. For a while, a guy held the world record with this caliber at 1000yds. Check out the 6mm BR web site, http://www.6mmbr.com/ There is a lot of good information there about the 6mm BR, 22 BR, 6.5-284. For the longer ranges, I use my 338 Lapua Mag. If I had it to do over again, I think I'd go with the 338 Ultra Mag. Same performance with a lot less cost.
Next comes the optics. You will need a scope that is clear and can hold zero. Target turrets are a must for long range shooting. The scope should be able to be adjusted and returned to zero. The adjustments should be repeatable like a tacital scope. There is a place called Kenton Industries that makes target turrets made up in yardages for several models of scopes. If you know the yardage to your target, adjust the top turret and hold dead on. No MOA. No counting clicks. No trying to remember how many clicks for each yardage. Whats now to like about this set-up. Jesse got his Elk this year at 1145yds using this set-up.
The scope will be an IOR straight 16X scope. From what I have been able to find out this scope is the best tracking scope you can buy for under $900. If you come across a better one let me know!! Tom.[/QUOTE]
Do you want me to let you in on a little secret?????????? I've been testing the newer model scopes from Millett and was very suprised? I have never been a fan of Millet scoped. They've never help zero to my satifaction in the past. A friend of mine wanted me to help him test the new Millett TRS-1 Tacital scope. I've never been a fan of mil-dot or tacital scopes. I was going to show Jared just what kind of **** Millett was puting out. To say the test was unfair is an under statement. The guns I was going to use were a 338/378 Weatherby Mag, 338 Lapua Mag Custom Rifle, 2 300 Win Mags, 6.5/06, 270 Win, 308 Win, 223 Rem. The scopes used were Swarovski, Nightforce, Leupold Vari-X III, Tasco Custom, Super Sniper. All the scopes except for the Super Sniper had higher magnifaction. The range tested at was 200yds. Let me make this short and sweet. Except for the Swarovski, Millett matches or beat the rest of the scopes and I was trying to fail Millet. To be fair, the scope bases were loose when took the millet off of the 338/378 Weatherby. It still grouped under 1" at 200yds. We put 200 rounds through my 338 Lapua and couldn't shake it loose. We did a box test at 200 yds and it came back to within 1/2" whish is my group size at this range.
Tom, check out Midway USA.com for the Millett TRS-1 scope. All the reviews are 5 star. The only problem is trying to find one. Midway sells them for about $300 but they don't have any. They are sold out as soon as they come in. I now have a Millett riding atop of my 338 Lapua. It used to have a Leupold Vari-X III 6.5x20. The Millett scopes model #30735 and up are worth every dime they are asking for. The 4X16 TRS-1 and the 10X TRS-2 cost around $300 or less depending where you are looking.
