I bought some alliant reloader 10x powder and 55gr sierra blitz kings to load for my 223. I thought there would be a load for this match up. (Did I mention I'm new to this). I did however find a load for this powder and 55gr Nosler ballistic tip bullets. Would I be able to use this load for the blitz kings or would it be different? The ballistic coeeficiant and the sectional density is close to the same (I'm not sure if that matters at all) between the 2 kinds of bullets. If you guys could help me with this I would appreciate it.
this might be a dumb question

- Start date
Start with the "start" loads and work your way up.
Learn to "read" the case for pressure signs and you will be good to go.
Also, if you don't have a chronograph budget for one as it is - in my opinion - a needed tool rather than an optional luxury.

Just back the load off a half a grain too a full grain. it shoould be fine aney ways but when the bullet type is spesifide the load is usaly toped out. what is the presher for this load.

That will be fine, as long as you start with the starting data. I usually don't find data for my exact bullet/powder combination, just use data for the same bullet weight.

x2 what everyone's said about starting below the max load and working.
The issue with different bullet types is not so much the differences in BC and SD, but how far they seat in the case. A bullet that seats deeper may exhibit a higher peak pressure than one tha seats further out. The location on the ogive where bore diameter is reached usually determines the seating depth and this may not correlate directly with BC.
X2, If you have a LEE Second Edition Manuel, 99% of the loads are just listed as Jacketed and then bullet weight, pretty much the only bullets that are specific are Barns and Winchester fail safe(in the Lee manuel) Do the above and you'll be fine.

Load for the bullet weight. Who made the bullet doesn't matter. Alliant gives 22 grains as a max load for 10X. Reduce by 10% for the starting load. Alliant did use a Sierra 55 grain spitzer for their load developement, but any 55 grain bullet will do nicely.

Sometimes true.
You have to be careful when you develop a load for a bullet with a long ogive (short bearing surface) and then swap bullets for one with a short ogive (longer bearing surface), because the pressure can spike especially if you are near or at max.
New bullet means a new load devlopment.
