Ok, i've had my Speer 14 manual since i've started reloading last year. I recently started loading .451 FMJ 230gr .45 ammo and have been using the Speer data. But also just aquired a Lyman 49 manual.
Speer lists the following for Bullseye:
Min: 5.2 gr
Max: 5.7 gr
I have been loading 5.3-5.4 gr loads and I initially noticed that recoil was much more stronger than the mid-load that i've used with W231 powder (can't remember the load).
So I get this Lyman 49 manual in the mail and look up .45 auto same load reads as follows:
Min: 3.8 gr
Max 5.3 gr
No wonder why my recoil has been "factory-like"
What do you guys do when you see varying data like this? I'm thinking of starting with Lyman's 3.8gr start load and working up from there. I don't think it could hurt any.
I guess my concern is why Speer's data is so much higher and should it be trusted? I'm thinking it could be, but I don't like running hot.
