Quick load help?

[Songdoger]

Just my understanding from the notes in VV page, the N565 is meant for heavier bullets. But I never tried. Let us know how it works out. I want to evnetually get away from all the Hodgdon brands.

Yes it's best suited for heavy for caliber cartridges. I've used it in 6-284 with 105's and 22CHeetah with 80's with amazing accuracy. Velocities were at least 100 fps slower with CHeetah vs 7828ssc or Norma MRP though. With the 300W/180 combo you can see in QL pic above 99% of powder is burnt before bullet leaves muzzle and has close to 25% ballistic efficiency. Of course that can vary depending on rifle and environment/area.

Norma powders are not currently available in the US. We don't know if/when tey will come back. IMR powders and all brands distributed by Hodgdon just shot up to about $80/lbs. Monopoly at its best. VV used to be the most expensive before covid, now appears in the mid range. I just don't like to be held hostage by one brand. IMR4350 and IMR7828 were my go to for 180 grains in my 300WBY. I have loads with RL (200 grains), and will eventually try VV.

Is 25% ballistic efficiency bad? Don't we want to try to achieve 100% powder burn

I can't find 7828 anywhere. I know it's the preferred powder in the WBY

Before 7828 came out, my preferred with 180 grains (it was a first gen MKV, 24" barrel, 12 twist) was IMR4350. There is a lot aof that around

Can someone please help me with quick load for my 300 weatherby. H4831 powder and 180 grn accubond. My rifle is a factory vanguard with free bore.

Darrin

I had a Ruger #1 in 300 Weatherby. I worked up to 84 grains of H4831 using the Nosler BT 180 grain. I used the Federal Gold Medal Match 215 magnum primer. I consistently got 3200 FPS and group average was 0.46" at 100 yards. I did not see or discover any pressure signs with this load in this particular rifle. I would suggest that where this load is pushing the maximum that start with a good manual and work up to pressure signs and then back off the load until the pressure signs disappear. Then refine your seating depth and headspace to find your sweet spot. Good Luck and good shooting.

Thank you so much for helping. Those ruger #1 actions are indestructible. I had one in a 7stw.

Do you just want the answer, or do you really want to learn?
A lot of folks are just in a race to get the highest MV. If that's all you want that's fine. If you really want to get the most out of QL you have to put some sweat in the game.
Accuracy with max MV is the name of the game staying within pressure parameters. Not the other way around. If you research and come up with weighting factor numbers for you rifle, starting pressure formulas, check your cases after firing to get real h20 volumes, that would be a good start.
QL program is amazing but can be frustrating to say the least.
I can give you some pointers from time to time to get you started if you're serious. Read the instruction manual all you can.
There's so much info can be a challenge.
Good luck !

Michael this isn't my first rodeo. I've been reloading for 28 years. Been studying long range for 14 years. So my problem is what a 300 win mag can Bo my 300 WBY does better. However the 300 wm used to have the military contract. Aka more testing with powders. N565 is loaded in my 2023 Vihtavuori loading manual for the 300 win mag from 150 grns all the way up to 230 grn bergers. No where is it listed for my WBY. Which I know will be good and work. So after my research came up empty I asked a question.

Darrin, you might want to download Gordon's Reloading Tool (GRT). Its free, very useful, has a lot of vidoes to help you started and discord support. Gordon, the developer passed away and development is kind of on hold, but there are plans to continue. Good news, it has the powders and projectiles you want, and It can actually help you tune your rifle with your data.

I still have about 3lbs MRP left that I got in late 90's. I don't work up any new loads with it due to the fact you stated. All powders and primers are priced insane. It's part of the plan. Not sure if mfg's are being imposed massive excise taxes or if they are just playing supply and demand games. I remember bitching when benchmark went above $30. Just got 8#'s shipped for $400. Just a lot more conservative shooting high volume cases anymore. 300 WM is safe Queen . 6-284 still gets some long range work but mostly shoot 6.8 spc and 223 to exercise eyes, technique and trigger finger these days.

Yep, I just shoot 22LR now, maybe 5.7x28 (rifle and pistol) and .223 . I have my loads developed for 30.06, 300WBY, 338LM and 375H&H. Will shoot only if I am testing before a hunt.

So the results are predicated on a 16.0" barrel length?

Didn't notice that Like I said it's what populated. At least it wasn't 40" like my 30XC.

Thank you for your replies. My barrel is 24 inches. Would that change?
