.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.

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.

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...

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.

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?
