200 grain ELD-X - IMR 7828 - 30 Nosler

[jcarey9730]

Hello all, first time poster but a long-time lurker. I'm not new to reloading but am new to working up a load with unpublished data and want to see if any of the more experienced reloaders would check me on my method. I'm wanting to use what I listed in the title simply because that is what I can find. It seems that I can find data for every projectile except for the 200 grain ELD-X. My plan is to start at 65.0 grains of IMR 7828 SSC and work up 1 grain at a time (5 rounds per load) and monitor velocity and for signs of excessive pressure with the goal of getting as close to 3,000 fps without sacrificing accuracy.
The comparisons I'm using are the loads for the 200 grain and 210 grain nosler accubond bullets. The 200 AB is a little shorter than the 200 grain ELD-X and the 210 ABLR is a little bit longer. Both show a range of 71.0 to 75.0 grains of IMR 7828.
Anybody have any words of wisdom for the new guy?
I appreciate your time.

I've not loaded for a 30 Nosler. But I'd do what your doing if I did.

I cross checked against 300wm, 300weathy and 300prc. 65 is 4gr below 300prc starting load. 300wm has starting load of 65.4gr. With case capacity (nosler info) the 300wm at 200gr ab of 81.1 compared to 30n of 87.5. 210ablr case capacity is a little closer 87.3(30n) and 78.2(300wm). Using 300wheathy the number are closer on capacity. 300why starts at 72.6gr for the 200edl-x. Just posting info, not suggesting. 65gr might not have enough pressure for bullet to exit barrel. I do have some 200edl-x for my 300wm, but haven't reloaded any yet. Are you starting at max coal? Be safe!

SSC or just 7828?

QL is giving 4.6% less case fill on ssc, but pressure is the same @ 35,495, exit pressure of 26" barrel 10,520. Hope it helps!
case @ 2.540" and coal of 3.340"

I am using 7828 SSC. I really appreciate your attention to this. I am loading them to 3.340" COAL. Sounds like I may need to pull some bullets and recharge. Think my starting load should be more like 68.0 and work up from there?

Probably start at 71 gr. https://www.nosler.com/30-nosler

I'm closer to @budlight 's suggestion and should be well under max psi, but enough powder for bullet exit? The crazy thing is Nosler data for the 200 and 210 have 7828ssc at 71.0 -75.0.

I saw that in Nosler's reference data and thought about using that data for the 200 grain ELD-X but wasn't sure if various bullet geometries could render that charge unsafe. Probably not, but wanted to be on the safe side. Certainly don't want to deal with having to dislodge a bullet from a barrel though. Given the data for the 200 AB and 210 ABLR being identical perhaps I should use that range for my application.

I used the 300wby as reference due to capacity and psi being close.
