I do not have the quick load data, but the #6 Nosler book shows 61.0 grs of IMR4350 as the starting load and 65.0 as maximum.
My buddies 300 WSM liked H4831SC and IMR4831, shot them both to about 1/2" 3-shot groups at 100 yards, to the same point of impact, and only about 20 fps difference between the average muzzle velocity between the two loads. They are as follows with the 180 gr. AccuBond.
H4831SC 70.0 grs. roughly 2940 fps or a bit more in his Winchester Model 70 classic sporter 24" barrel
IMR4831 65.5 grs. Same m/v or at least not enough difference to matter.
Both loads shot great. I did try IMR4350 and W760 and it did not work as good as the 4831's did.

Russ - that Nosler Brass significantly better than other choices?
Am well set for .300 WSM brass for now, mostly Norma, some Winchester. Just wondering about the Nosler.

I currently use RL-17 and get great goups with 66.9 gr federal 215 primers and COAL 2.912 with Nosler 180gr Sp. with 24" barrel on a Tikka3 SS

Something doesnt look right here. I use RL-17 with 66.9 gr, and get 3050 fps with a nosler 180 gr BT SP.
Aliant's own reloading recommendations for the 180 gr and RL17 is 66.0 gr and it shows it produces 3082 fps. ?? :?:

When you run a "charge variation" chart with QL, the pressure parameter is set at 85% of maximum by default. The reason for this is to allow for lot-to-lot variation in powders. You can reset the maximum chamber pressure. What is important to stress is that QL cannot be a substitute for pressure tested loads. Moreover, each hand loader must assume responsibility for recognizing the signs of excessive pressure and understand how to avoid getting into trouble. Whenever you use data generated by QL, it is a marvellous adjunct to loading, but the one doing the loading and shooting is still responsible for his actions.
Consequently, examining Antelope_Sniper's data, you'll notice that as you approach 65K psi, you gain a whole 20-22 fps. The safety factor does not negatively impact the velocity in the real world.

Alliant's data is generated with the Speer 180 grain BTSP, which has a shorter bearing surface. Also, Alliant uses F215 primers; whereas QL assumes you use the coolest primer available to ensure ignition. In this case, they would likely assume an F210 primer, which would generate several thousand fewer psi and hence, less velocity.

BN, just playing around with it on a couple of different calibers I saw instances where the max load would change by 4% with different bullets of the same material and weight. Changing case capacities can also make a difference. This can be used to simulate different makes of brass ect. Just like all the loading manuels we use, it's just one source, one I'm still learning about.
