Trying to get over 3000 fps for 300 WM and 180 grain Accubond

[slikmrc]

You should be able to find a starting load for RL 19 using Speer load data. Another good powder to try would be Accurate Magpro, have seen it on the shelf at a couple different stores. Not the most temp stable powder, but has worked well for me in the 300WM and 300 WSM.

All good points fellas, some windier than others, but all good. A few points:
1. I would NEVER sacrifice accuracy for speed
2. AS OF NOW, and the graces of a muzzle brake, recoil isnt an issue
3. I am currently shooting .31" (3 shot) groups at 100 and 1.13" groups at 200 and 300…at 2932 fps
I was hoping to squeeze a little more speed out of my 300 WM to see if a little playing around could do it. But AGAIN, I was hoping to get a bit more speed with the same, or better, accuracy. If my groups blow up due to added speed, I will stick with where I am at and go with it. I appreciate everyones opinions, perspectives and experiences. Thanks.

I like vithtavuori powders. My go to for speed. You won't get enough n570 or even n565 in a wm case to get 3000fps. I couldn't even get that in my wby case. If I remember right it wouldn't get but 2850 with n565 compressed. N560 or retumbo is what I would try. I settled on retumbo for my 300 wby and 180s. It's running 3140fps.
I'm like you. I want speed if it will shoot. If it doesn't I'll back it off or find it a new home. I wouldn't go with any alliant powder unless you have a stock pile of it.

Top Gun came out in 1986. Home Improvement came out in 1991.

Wow!!!!! Lmao

What would a MIN-MAX load of RL-26 be?

I never read all the post but in my 300 Win with the 175 Barnes LRX with a max load of RL-26 (76.5 grs in my rifle) in a Rem case lit with a CCI 250 I get 3225 ft/sec. I've use many powders in my 300 Win and none can do what RL-26 does. The problem is to locate some. JME

Centerfire Rifle 300 Win. Magnum Speer 180 gr SP Reloder 19 CCI 250

Case ​	Minimum OAL (inches) ​	Bbl Length ​	Primer ​	Powder ​	Charge Weight (grains) ​	Velocity (fps) ​
Winchester	3.34	24	CCI 250	Reloder 19	76	3,059

You must also always remember:
1.Establish a routine for reloading. It will result in more uniform loads and less chance of error.
2.Some primers are more powerful than others (they produce more gas at a higher temperature). Use only the primers specified herein.
3.Shotshell wads differ in their sealing ability. Use only the load combinations specified herein.
4.If you use cast bullets, their diameter, hardness, lubrication, and crimp will affect the ballistics.
5.The shotshell loads in this booklet are for use with LEAD SHOT ONLY!
6.Use only the brands of powder and components shown in our tables. Do not substitute other types.
7.Discharging firearms in poorly ventilated areas, cleaning firearms, or handling ammunition may result in exposure to lead, a substance known to cause birth defects, reproductive harm, and other serious physical injury. Have adequate ventilation at all times. Wash hands and face thoroughly after handling and before coming in contact with food, chewing materials, and smoking material.

For a Speer 180 soft point. I'd knock it back to 71 grains to start.

RE-22 has always worked well for me in the 300Win mag too.

I don't personally understand the need for speed pursuit....never will....guess that comes from being old! Never understood getting Old either.... Accuracy, Accuracy Accuracy....is what kills, and for me Barrel life is an added bonus.....just me

It's not a big mystery, more velocity = More energy and less bullet drop.
Flatter trajectory and less wind drift = less error to correct for.
Is the difference between 2900 and 3000fps enough to make much difference?
In my opinion, 300yds- no, 600yds-maybe, at 1000yds-yes. But if group size is sacrificed for speed, then you are right, it's a fools errand at any distance.

I have been working on an elk load for my 300 Win Mag. I have chosen to shoot either a Nosler Accubond or Barnes TTSX, both in 180 grain. I have worked with H-1000, but even a compressed load gets me to the low 2900 fps range. I have been thinking of trying RL-19, but havent found powder Min-Max amounts yet. Does anyone have those powder numbers or another powder I could try to get over 3000fps? Thanks for any help. I appreciate it.

Your h1000 is to slow for that. I ran into the same with h1000 and 190 ablr. It got too compressed before I ever saw pressure signs. In my 24" savage 300 win mag, 190 ablr got 3000 with h1000 and n565, and 3100 with rl26. 165 ab got 3300 with h4831sc.
