I think I have asked this question before but couldnt find it using the search.

I have been loading 67gr of rl22 behind a 120gr swift a frame for over a year and shot many of them in that time frame. It makes a 3 shot group under a half inch @ 100 yards. While going back through my notes I found where I wrote that load dataa down. But I couldnt find published data showing it. I found on aliants web page a load of 63grs for a fps of 3100. Can anyone help me with published data? Im starting to think I might be over max at 67gr.

Slamms listen If your unsure about a loading, just start over, and if your sure about your loading and it's written, and you've been shooting it for awhile, what's the problem?
In my loading I use labels to tell me what the five cartridges in the bag are, when I shoot the load I stick that label on the target, when I get home I study everything about the load, (including range notes, like excessive pressure, weird shot noise, hard bolt lift, etc.) then I work from there, I find something I might want to further work on, if not the target and the data go to the trash, and I start the further work-up on the keeper data.
Only after I prove a load to be the best for what I'm wanting will it get written into my black book, and I call this load " The One".
It works for me, although sometimes I can't remember what data I have tried, ( "ole-timers") but if it's written, then I confidently load multiple boxes and practice.:)

I have 7 loaded left from the box of 100 that i loaded. So i have shot 93 of them. After finding the load data I wrote down in my book similar to the way you do it. I went ahead and measured each coal, then pulled each bullet and weighed each charge. All of them where right at 67gr. There has never been any sign of over preasure of any kind. My only concer is I always use published load data and never experiment. I cant find any published data stating this load. Thats the only reason I am worried about being over.
 
There is no easy answer for your question, no data I saw listed your bullet and your powder spot on. Safest is to contact Swift for their load data for your specific chambering with the powders they used to develope THEIR LOAD DATA. If you can't find published load data using the Swift A frame bullet and Alliant 22 powder I wouldn't pick a number out of the air.. The generic steves page info is what it is, I wouldn't trust a 18gr min to max charge, think about it!! William

If its working, its working. When Rl22 first came out, many people joked that the data for it was "as much as you can pack into a case." With my experience with it, that aint too far from being true with all but the largest cartridges shooting the heaviest bullets. The published data on Weatherby cartridges today is insanely conservative.
