I was wondering if anybody would be willing to send me some quickload data for a non-wildcat cartridge. Specifically 7mm-08 with a 140gr and 150gr Nosler Ballistic Tip so I can get a decent starting point. Nosler website shows near identical charges with different size bullets and different relative capacities. Seems kinda iffy to me.

Only have a couple powders in mind. R15, H4350, and Varget. 24" barrel. Max pressure 60k psi (margin for error). Those are the "cheaper" and readily available powders out here. Open to a few other powders, just may not be able to find them.

Any help is appreciated. Most people here seem really helpful.

Thank you. That pretty much answers my question right there. Nosler lists the usable case capacity at 48.6gr H2O for the 140gr and 47.8gr H2O for the 150gr using an OAL of 2.8". I don't have any fired cases to compare it to as I haven't loaded any yet. Nosler also lists a max charge of 41.5gr of RL15 for both bullets, as an example. QL shows 42.0gr for 150 and 43.2gr for 140. Won't be exact, just a rough number so I can make a safe starting load. I was curious when people were saying loads of 43.0gr with the 140s showed little pressure signs even though its 1.5gr above Nosler's max.

most companies loads are a little conservative on purpose so people don't blow them selves up.

That is true, just seemed odd to be the same charge.

Looking at the Nosler numbers again, the 150gr numbers are almost the same as QL. The 140gr ones are close with all powders except RL15 which is a big 1.7gr difference. Makes me think it's just a typo. Thank you for verifying the load data. I like RL15 in .308 which is why it caught my eye.
