.300 weatherby load

[MuleySniper]

I'm still pretty new to reloading. Yesterday I took out 20 rounds of two different loads I worked up. IMR powder (don't remember which one I'm at work) CCI mag primers, Weatherby once fired factory brass and 180 grain Nosler Partitions (factory seconds). I'm using the Speer manual. The first load I shot I used 72 grains of powder and I wasn't real impressed. The second batch I used 76 grains and they were working pretty good for me. I was shooting  three rounds at a time then would let my barrel cool for a bit and switch to the .204. Needless to say, I think I will try something different the next time around. Anyone have any tips for increasing accuracy? Bad thing is, after about twenty rounds my shoulder starts screaming at me so I think I lose accuracy just in my shooting ability. Also, if anyone has any other loads worked up that work well, Id like to hear it.

Buy a leadsled. My birthday is coming up, buy 2!!

We use cci magnum primers and 79 grains of h4831 and 180 grain nosler accubonds and are happy with that. 79 grains is 2 grains under maximum but has less recoil.

Looked at em like 5 times in Nachez today

I was thinking of ordering some accubonds and giving them a try. Ive also read 150's work good for dialing in if your going to be shooting a few rounds. Save the shoulder.

When doing a bunch of shooting off the bench with my .300 Win mag, I wear a recoil pad on my shoulder.  Before using that, I would get my shoulder bruised up after 10 or so shots sometimes.

Here is a link to see a picture of what I'm talking about: http://www.buffaloarms.com/browse.cfm/4,3167.html

(You can also where it under your jacket in case you're worried about other guys giving you *censored* for being a *censored*.......)

Nothing cool to add, just marking some territory on this thread so I can refer back to it.  CoryTDF and I are supposed to start working up some loads for my .300 Wby later this week.

[wastickslinger]

Try a  Limbsaver. 509er talked me into one and it makes a pretty big difference. They dont look bad either.

I put on on mine too.  Made a big difference, but it still kicks like a mule...

[haugenna]

180 grain TTSX
Federal 215M primers
IMR 7828

That was the best combo my father in law found.  Not entirely sure on the powder charge.  1.5" at 300 yards was the best group they achieved.

Try a muzzle brake...they make a lot of noise, make a big difference and look cool too.
 

[MuleySniper]

Yeah muzzle breaks look cool on bolt actions but not on my #1 I actually have a stock Ive been building for about two years that has a real nice pad on it. Just need to finish it up. Problem is though once its all done she'll end up being a bench gun/safe queen. Thanks for all the other tips!

They make to much noise if you ask my wife! She has yelled at me more than once

I had my Vanguard 300 Weatherby barrel worked by Mag-Na-Port and the ports are barely noticeable.  Takes a lot of recoil out.  I also have a limbsaver.  For accurate loads you can try to keep everything consistant.  Weigh the brass and bullets.  Find 20 cases that are  within the same range, maybe within a half grain of each other.  Weigh the bullets.  I have some 140 grain Hornady's, for my 7mm Mag., that range from 139.3 to 139.9.  I broke them up into three groups, a low, middle and a high.  I have two scales and I measure the powder twice and check a sample group before loading the bullet.  Since my Weatherby has a long throat I can't adjust the bullet's ogive which can help accuracy in many cases.  If I can adjust the ogive and still load rounds in the magazine, like I can in my other rifles, I try to get the ogive about .025-.030 inches from the lands of the rifling.  If you can use a chronograph to test your loads, all the better.  I don't have one, but I get a ballpark figure from ballistic tables in the Speer handbook.  I sight in the load for 200 yards, shoot a group at 100 yards, measure the height above the bull and use the bullet's ballistic coefficient to find velocity from the charts.  I need to get a chronograph, would be much more accurate.  I use 180 grain Hornady Interloks with 84.5 grains of IMR 7828, CCI 250 primers and W/W brass.  I put the rifle in an Outer's cradle and get some one inch groups.  (Oh, I also had the trigger adjusted)

Thanks for the tips! I cleaned up some brass yesterday. From talking to a few old timers at the range and input from here I plan on working up  some hotter loads. I started with the lesser grain. Sounds like its better to work up to faster loads. Another nubie question... I have a RCBS powder throwing deal that I have used to reload quantity .223. I weigh every three throws to make sure they are the same. Im pretty sure its obvious, but should I weigh each load individually when loading .300?

[hunterofelk]

I have a RCBS powder thrower, but I only use it to get an amount a few grains below my target load.  A powder trickler is used to reach the load I want.  I wouldn't trust the thrower to be spot on.  Since a person testing loads probably only loads 20 rounds, weighing everyone doesn't add too much time.

[MuleySniper]

That makes perfect sense. I was just reading an insane write up a guy did on 24hourcampfire under reloading on long range shooting. I can see how this can get intense!

Advice:
The limbsaver is awesome, we put them on all our big guns. Well worth it, they even make a slip on if you don't want to put on a permanent.

More Advice:
If you shoot a lighter bullet the recoil really drops off, you know the whole equal and opposite reaction thing. So try some Barnes Triple Shock in 150 or 168 instead of 180's. The Barnes normally hold 100% of their weight and will penetrate deeper than a 180 that loses 30% to 50% of it's weight. I can not think of an animal that they have not gone clear through. Just give em a try, you will become a beleiver.

I do need to mention, the Barnes are sometimes not quite as accurate, but the average shooter will have a hard seeing the difference most of the time. The key is to just give em a try and see how they group.

[bearpaw]

One warning I would like to offer:

I hate muzzle brakes and attribute my loss of hearing to the rifles hunters bring who  have them. No matter how hard you try to wear protection, there will be times hunting when your ears are going to get a full dose of deafening rifle noise with those brakes....

[MuleySniper]

Thank Bearpaw, I'll order some Barnes 150's and give em a shot. I also like the idea of the slip-on limbsaver pad. Normally the kick doesn't bother me, actually none at all when shooting an animal but it would be nice to have at the range when there isn't any adrenaline coursing through the veins.

I shot a .300 WBY mag for alot of years and always loaded my own. The VERY best and MOST accurate combo out of my rifle was Federal 215 magnum primers setting off 83 Grains of IMR7828 behind 180 grain Nosler partitions. It was a deadly combo. Good luck. I love my Weatherbys.

[MuleySniper]

Yeah Ive always shot Partitions. Factory ammo is pretty spendy hence the reloading. I have tons of once fired weatherby brass. This go around I plan on customizing my brass to this particular rifle. I'll try some 215 primers (if I ever find any), some of the mentioned powder and load up some 150's and some 180's. Thanks again for all the tips! I really really want this guy accurate for my late Entiat hunt

I shoot a .300 win mag with 165 gr nosler accubonds and my son shoots a 7mm rem mag with 140 gr. nosler accubonds. My opinion is that with the performance of this type of bonded bullet you can go down in grains which will reduce recoil tremendously in addition flatter shooting for those longer shots we might encounter up in the entiat.(lol) The higher velocities of the 300 weatherby mags and other magnums before bonded bullets we needed a much heavier bullet;not the case anymore. We have shot Mule Deer and Black Bears from 50 yrds to 350 yrds. and these bullets have performed excellent with quick one shot kills. Our velocities are 3000-3100 fps. I use Reloader19 and WLRM Primers in both of the loads.

[loaderboy]

Im shooting the nosler etips in my 300 weatherby and they are shooting 3/4 of a inch at 100yds. my load is 85 of imr 7828 my speed is 3220fps. be careful and start with light loads with the etips and watch for pressure as you slowly move up. my gun is a christensen arms with a 28 inch barrel and it has a muzzlebrake and the recoil is less than a 30-06.

Lets save some money here folks.....

How 'bout just rolling up a dang-me old dish towel and placing it between your-self and the rifle?

Is that just too dang-me simple, or does it just not cost enough? That why you folks like buying 'brakes and 'sleds??? You have more money than sense???


Look folks, shooting off of a bench is for one thing, load development.
It ain't like real world shooting, you ain't gonna pack no bench with yourself up in the woods, not unless you are like Dan Lilja and shoot a massive rifle pushing big bullets out past 2000 yards. Nothin' wrong with that either, if your set up for it, but if you are shooting a reg'lar rifle, you should practice with it like you'll use it.

For load work??? Use a towel, take the money you just saved and buy some more boo-lets!

Good Luck, I'z also got a 300 Weatherby, it shoot flat based boo-lets very well.

[littletoes]

I need to mention, this last post was made with "Love", and some kidding. The rag really does work, and its cheap, just don't steal your wifes best one! 

For load work, Weatherby's have quite a bit of free-bore, and flat-based bullets "jump" better.

Good Luck, Good Shooting!
