Hi has anyone got any vectan A0 surplus tonrequirement I’d like to try some cheers

Hello chaps. I just ordered my first lot of reloading kit from Clay & Game. Very excited about getting started. Before I start, I will say that C&G given me very good customer service over the course of several weeks to help me work out which bits I need to buy and I recommend using them if you can - and no, I haven't been asked to say that, but given how much time they've spent answering my amateurish questions lately, it's the least I can do. Anyway - I've bought stuff for a 16ga load and a 12ga load. I've got the recipe for the 16ga load sorted, but I'm having trouble with the 12ga load. I'm hoping some of the resident experts can help me sift through the data and sort it out. I've got the following for Vectan A0 in an 70mm Cheddite / CX2000-primed case: Gualandi: 12 / 70 / 616 or CX 2000 / Plastic Wad / 1.80-1.90g / 38-39g / STAR Folkstone Engineering Supplies: 12 / 70 / 616 / 1.85g / Fibre Wad / 36g / STAR Nobel Sport: 12 / 70 / CX2000 / 1.80g / Plastic Wad / 40g / STAR Clay & Game: 12 / 70 / CX2000 / 1.62g / Plastic Wad / 36g / STAR (8pt) Ideally, I'm looking for 36-38g of shot on top of a fibre wad at 1150fps-1200fps, though none of those recipes give velocity information. My thinking is along the following lines: The Clay & Game recipe seems a bit conservative, compared to the others, but it does give a pressure of 727 bar which is close to the 12 gauge limit. It also uses an 8pt crimp, which I assume is to keep the pressure down? The above said, the NobelSport 40g load also gives a pressure - of 700 bar. This seems contradictory. The use of a fibre wad as opposed to plastic should lower the pressure a bit, and maybe give me the option of a touch more powder or shot. I know the plastic wad dimensions and can substitute an over-powder card and fibre wad. I'm sure I must be missing something here, but on the basis of the above, I'd say a middle-of-the-road approach would be something like: 12 / 70 / CX2000 / 1.80g / Fibre Wad & Nitro Card / 38g / STAR Questions: Does this seem reasonable, or have I - as I suspect I might have done - missed something about the Nobel Sport and Guialandi data which means that they are for a higher pressure limit than the 740 bar I see referenced all over the place? Can anyone tell me what I should actually take as the "maximum load", since they seem so varied? I can then at least stay within those bounds and be safe. I'm not looking to lose eyes / fingers / my life here - just come up with a decent, heavy 12 gauge load in the 1200fps range. Should I risk a 6-point crimp, since the "hotter" data doesn't specify one, or stick with 8-point? I've ordered new cases, so it makes no difference to me really. Just rather be safe and keep pressures as low as possible. Many thanks for any assistance you can give, Adam. Edit: Added ​comment about Nobel Sport data pressure. ​
