Reloading different bullet brands of the same weight with one type of powder

Reloading different bullet brands of the same weight with one type of powder listed on one reloading manual.

I hope this makes sense. I read on a different thread that someone was using 300 grs bullets from different manufacturers with XY grains of one type of powder, this was for a 375 H&H. The results according to who did this was positive and POI was very close with most bullets. I asked if he had noticed any pressure signs with the different bullets and I was told not at all.

So, with powder shortage, and how every reloading manual has their own powders they use. Would this be a good idea, (I know, I know) to let's say, use 180 grs Nosler bullets for 300 H&H, with powders listed on a Barnes or Sierra reloading manual for the same bullet weight? Obviously starting with minimum load and working up watching for pressure signs.

I've always used the powder that the reloading manual recommends for the bullets listed on the manual, I've never switch from one to the other. I've compared the different loads but never done any switching. Your thoughts are welcome.

other than Swift bullets, with the higher shot start pressure, it is the bullet seating depth that affects the pressure and use the manual that has similar bullet style and OAL.

I asked this question once when using a bullet not listed with Vihta Vouri powders. When I contacted their tech support, they said the bullet weight wasn't as important as "shape", i.e. ballistic coefficient, length, etc. In other words, compare the bullet I was using to others listed in their tables, and look for similar weights and BC. From there, start small and look for signs.

The specific instance in this case was trying to use an RWS Scorion bullet in .30-06. The comparison was a Lapua Scenar, and the result was about .75MOA.

I think when switching from jacketed lead to monometal the load data can go out the window. My load data for 400 Gr monometal solids is about 4 grains different from the lead core softs.

I believe you are correct, but their can be outliers.

My .470ne uses the exact same load for 500gr woodleigh weldcore SP as it does 500gr Hydro solids.

Is the monometal bullets 4gr lower than solids? Are they longer?

Lower grains for monometal solids, and yes, monometal is substantially longer.

Thank you all for sharing your experiences.

For years I have loaded Hornady interlocks, Nosler partitions, Speer hot cores and Sierra game kings of the same weight and caliber using the same powder charges interchangeably. Same POI, same velocitys. The monometal bullets and solids are certainly different. I would think that the Swift A- frames may also be different but because of their cost and availability I don't shoot many of them.
