150 gr BST 7mm WM for deer & elk?

Would the 150gr, BST weatherby factory ammo be adequate for deer & elk?
I'd like to use one bullet/load for both

What about Barnes-X too?

I am assuming the weatherby's with spire points would not be good-though they are the cheapest.

If you use a similar train of thought as for the 7mm remington magnum, you should be safe as far as predicting the capabilities of the 7mm WM. The rounds are similiar. I think the 7mmWM has about 120 FPS more then the 7mm Rm.

The barnes reloading manual has 150gr barnes-X bullets ripping out at 3190 FPS. I have never used Barnes but a guy at work uses them on his 300 Weath. M. and swears by them. He hunts elk, deer, moose and bear. On a down note, he does say that the bullets tend to clog the barrel. The copper is kind of soft and fouls the barrel easy. The ballistic coefficient of Barnes bullets is very good too, but they are pricie.

What would be wrong with loading a nosler partition with IMR 7828 at 76.5 grams w/fed 215 primer @3390FPS for deer & elk? Or, would a 160 gr spitzer with H4831 & H1000 be better. Don't know much about Hornady SP's which could be a compromise with a 154 gr and IMR7828 @ 74.5 grams & 3250 FPS

You can't just pick a bullet, powder charge/ make, primer make, cartridge case make the round and load it into your rifle thinking it will work great. When reloading you have to work up the round. Starting from the lowest charge for the round you want to make. Work it up a 1/2 gr making 5 rounds of each charge till you get to the safe maximum. Then go to the range and see which round gives the tightest group and if you have a chrony..the best velocity. Then you calculate the energy using a formula. This way you have the most accrurate and hardest hitting round for your rifle.

Or if you know anyone who has the exact same rifle, you can see what round they have developed. If you're interested in reloading and the theory behind developing a round for your rifle let me know and i can go into detail more. There's no point in telling you things you may already know . Reloading is a cool hobby!

No, I know mothing about reloading! But, with the purchaes of the weatherby 7mm wm I am highly motivated to get into it and learn. Tell me all you know brother. I'm bidding on items on ebay as we speak. Such as, Press, dies etc.
Ammo for this jewel is $$$$$$. Think i will buy 2-3 boxes of weatherrby ammo. probably 150 NP or some such and get the brass to get me started. Lets' get started.

While 7mm Mag 150-gr. Ballistic Silvertips will do a superb job on light-skinned deer, heavy-boned elk are another story and require a tougher bullet like the 150-gr. AccuBond or Partition.

Ok cool. Before you start spending cash, give me a day to get a list up of the basic things you will need. I'm going out to my shop to see if i have any old targets to show you how the bullet pattern tightens up. Reloading for your 7mm will save you a bit of money, but the best thing is you get to "Tune" your ammo to your rifle.

The following pics are an example of how the group pattern tightens up. This is my midland rifle (parker hale) in 270 WIN with a 4x tasco scope. Shot at 100 yards, sitting. 5 shot group. The powder i used was IMR 4831 (a slow burning powder) worked up in .5 gr increments. The bullets were Speer 150gr spitzers. CCI primers, winchester brass.

The starting load was 51GR up to 55GR as per the speer reloading manual. I got up to 52.5 before my group started to open up. I never Chrony the velocity because i was creating this as a predator round and not a hunting round.

The pics are as follows. (note the coin is a canadian dime i used for size reference)
1) 51gr of 4831 (yes i know the group would have been a bit tighter if i didn't have a bit of a breathing problem but this series of groups was shot near the end of the day and i had already shot 180 rounds before this 20. kind of tiring to hold it together for that many accruate shots Think )

2) 51.5 gr of 4831. The group tightened up a bit.

3) 52 gr of 4831 notice how the group came right into "focus". There are five rounds there, the edges of the holes touch each other. This is the ideal load for accuracy in my midland using the above component combination.

I ran out of pic posting space so my next post will describe and show the 4th grouping.

150 gr BST 7mm WM for deer & elk?

Groupings cont. This grouping is 52.5 gr of IMR 4831. Notice how the grouping is starting to open up and the "flyers" are back? Shooting any farther then this would be a waste of bullets so at this point i "unloaded" the other groups to save bullets/ powder etc.

The first step you should do is pick a bulllet you would like to shoot. Then go out and buy a reloading manual form that bullet manufactuer. I would suggest a Nosler or a Hornady. Those manuals do have general instructions and info to help a new reloader. For reloading equipment i think best value/quality is RCBS. LEE is cheap and i would stay away from it. If you like PM me and i'll give you my email address and i can send you more info/ answer some of your questions etc..or we can post in the forum but i'm not sure if the moderators would like us to take up that much space. Let me know.
