Beginner 7mmWSM Reloader

I have been giving serious thought to reloading my 7mmWSM(winchester model 70 Shadow/26" barrel). I am considering using the new Barnes Tipped Triple Shock Bullets. I have read up on Barnes bullet a little and they seem to be pretty popular. I am asking for suggestions and guidance on reloading this round. Also, are there any mods that a guy can do to the barrel/stock to make it more accurate? Any and all information would be greatly appreciated.

What do you plan to hunt with it? Swift Scirrocco & A-frames and Nosler Partitions work well on tougher game also. Try a few different weights and brands and powders to determine what the rifle likes.

Welcome to the site Ryan. I would suggest to learn reloading using standard cup and core bullets. Then use the premium bullets for hunting if you want. Much cheaper that way.

There might be things you can do to the stock to gain accuracy but, how much do you want or need and what is the rifle doing now. Often I have seen rifles that benefit from bedding, I think most do. But my newest rifle I haven't touched and it shoots fine. I'm not going to mess with a good shooting rifle. If your getting 1 1/2" @ 100 or less, you have decent hunting accuracy. But if you want more bedding and load developement will probably get it for you. If you want match grade, I'm the wrong guy to give an answer to that, don't shoot and never have centerfire match.

Im mostly going to hunt elk and bear. Maybe a coyote here and there. Im not a man of many guns so I dont have the luxory of having a range of calibers to choose from. Just my 7mm and an old 30/30. I dont know what those type bullets are but a wild hypothesis says that they are just basic, inexpensive rounds to gain experience from. As far as accuracy, last time I shot at 100 yards I had about a 1 1/4" 3-shot group. I read in a magazine where you do something to the end of the barrel and it gains quite a bit of accuracy. At least that particular gun did. It went from like a 2.5'' group to a 1.5'' group at 100 yards. Anyways, I want to be able to shoot 1 moa or better at 100 yards(thats a 1" group, correct?). I know shooter error is a big factor also, but Ive read somewhere that if you get the perfect load, your rifles accuracy goes way up.

I wouldn't be upset with what you have now. Probably if you ran 10 three shot group's thru it you'd get several an inch or better and several up to 1 1/2". I have no idea what they did to the barrel but have heard of some deal similar to the old cutts compensator thy tried out that would tune the barrel. I wouldn't recommend it tho. If those things were all they were made out to be, the gun makers would install them on factory rifles. Come to think of it I believe Brownong did have what they called a Boss system they used. Must not have been that great as I don't hear about them any more. Most gadgets are just that, gadgets designed to get people to buy something.

Your 1 1/4' group is so close to where you want to be that probably good reloads will get your there.

Your right about the basic inexpensive rounds (bullets), that's just what they are. If you find one brand bullet doesn't shoot well for you, try a different brand. Sierras are known for accuracy but a bit fragile in game. I've had good luck with 160 gr Speers in 7 mm Rem mag and 154gr Hornady's in 7mm. But you'll probably be pushing a 160 gr bullet fast enough in yout short mag to warrent a premiun bullet on game. I'd recommend one but I don't use them, I'm a cup and core shooter. If I were, I'd look at the bonded core bullets myself. Nosler accu bond., Hornady Interbond and the Swift bullets. Don't rule out Nosler partitions either. Very good track record for a very long time. My choice here is the Interbond but, I am predjuice strongly for Hornadys. I also don't shoot magnums anymore.

Thanks for all the help Don, I will try out different brands and types. Even if the first round I try is adequate, I will still try out other types just for the experience because there is nothing better than that. That way I should be able to learn both ends of the spectrum (great shooting bullets and not so great). Id assume that how a certain bullet (grains,type i.e. boattail) shoots in one gun doesnt particularly mean it will shoot the same in all guns. i.e. 7mmWSM compared to a 300Mag.? Is my analogy correct or am I way off kilter?

Also, Im kind of in the dark when you talk about "core bonded" and "cup and core", I dont know what those terms mean. Is it something I will just learn when i start reloading?

Your pretty much right about one bullet working differently in different rifles. Little deeper than that as say a 160 gr 7mm bullet and a 180 gr 308 bullet would both preform equally well in their respective cartridges.

As for cup and core and bonded bullets, they are very similar. in each a jacket made of guilding metal is formed and refered to as the cup. Inside the cup goes a length of lead wire that is the core. The thing is then run into a forming die that gives the bullet it's shape. The difference in the two is that in the bonded bullet a process is used that bonds the core to the cup holding them together better and lessing the probably of core jacket seperation. The old Speed Hot cores were similar to the bonded bullets but not really bonded. But they did keep the core and jacket together very well.

Now, how importand is that? On deer or even elk, I'm not so sure it's all it's made out to be. If you were to use a proper weight bullet in your short mag, a regular cup and core should work well. But you'd have to stick to heavier bullet's. While the velocity of a 140 gr bullet out of your WSM would likely tear up a standard cup and core bullet on impact at closer range, the same 140gr bullet in TSX style would not tear apart at magnum velocity. I have fired a good many cup and core bullets out of 7mm Rem Mag's. 130/140 gr bullets had the disgusting habit of giving poor penetration and/or a lot of internal damage indicating a bullet shedding to mush weight to fast. On the other hand, mt favorite bullet was the old Speer 160 gr Hot Core. Never a problem with that bullet. A combination of bullet weight, construction and velocity that worked very well at 7mm mag velocities.

Chosing bullet's can be a very confusing thing. The problem is that light for calibre bullets don't generally work well on big game. Enter the TSX bullet's and the light for calibre bullets hold up! For prnrtration, they depend on velocity rather than weight where as with lead core bullets, the same velocity that a TSX will take will tear up the same weight bullet. To over come that with the lead core bullet you either go up in bullet weight or down in velocity. The bottom line is that a bullet that penetrates thru the vitals and is well placed, kills effectively reguardless of it's construction. I cannot imagine any animal on the face of the earth that could stand up to a cup and core bullet that was properly choesn in a proper calibre. At the same time some anti premium bullet nuts have claimed of TSX type bullet failures. The photos they show to prove it clearly demonstrate wounds not possibly made by those bullets. Is the TSX a better bullet? Well maybe and maybe not. If the Remington core lock is already shooting completely thru an animal and killing it quite dead, what's the advantage of a TSX type other than to make the user feel good? Nothing, it's probably in reality over built, at least for North America. Many people in this country are still having very good luck with rifles that shoot slow lead balls and weapons fireing sharpened sticks.

Not necessarily the first thing to do, but I would have the action bedded properly by someone that knows how to do it. I never met a rifle yet(no exceptions) that couldn't benefit by some bedding.
I don't know how familiar you are with reloading but any rifle with a 26 inch barrel loves the slow burning powders,my favorite is H4831, and with that you will achieve your best velocities/energies.(or similar slow powders)
The boat-tailed ballistic tipped bullets that are very popular are not going to do wonders tightening up 100 yard or 200 yard groups. Those "magical " projectiles really don't do anything special until you're out 350 yard and further, so don't waste the extra $$ at the get-go

To let you know just how finiky some weapons can be to loads Ryan, I have a matched pair of rifles that My son got "me" (lol was kinda an US thing) for my B-Day. While one absolutely LOVES a 180 grain the other one wont hold a 2 inch group with it. Load it with a 160 and she drills clover leafs all day.

The rifles serial numbers are one right after the other. Came off the same tooling bench and all. Rifles can be the pickiest heiffers on the planet, INCLUDING women!!!!

Im still in the process of buying the equipment i need for reloading so in the meantime I learned how to adjust my trigger and boy it sure makes a huge difference! I even did a small amount of work to the foreend of my synthetic stock and I think that helped by making the barrel a true full float. Does anyone have any suggestions on brands for reloading kits for a beginner?
