I was think of working up a load with Sierrra's 45 Gr soft point bullet and LiL Gun powder and found a great difference between Sierra's data and Hornady's Data for the 45 gr bullets. I have just sent an email to Sierra but I'm sure I won't hear back until at least Monday but hear is a copy of my question to see if any of you might have some insite.
"I'm going to work on a load for my CZ 527 .22 Hornet. I have a box of the Sierra 45 Gr. Soft Point bullets (1210) that I was going to try. I have the Sierra manual Edition V, 7th printing. In this manual it list Lil' Gun starting at 7.1 gr and a max of 8.9 gr. Now I also have the Hornady 9th Edition manual that I was just checking to see how the data compares to each other and there is a large difference in the data. I know that different guns were used to work up the data but both books used Winchester brass. Sierra used Fed 205M primers where Hornady used Winchester WSR primers.
Now what has me scratching my head is the Hornady info for Lil'Gun for their 45 Gr bullet (2230), which I do not have, starts at 9.5 gr and has a max of 11.7 gr. Is there such a great difference between these 2 bullets that Sierra's max load is less than Hornady's start load or could one of the manuals have a misprint?"
Now looking on Hodgdon's site their info starts at 12 gr and has a max of 13 gr.
Are there any more experienced Hornet loaders here that might have already been down this road?

John ~
I started hand loading in 1964 and I can't tell you the number of times I have found similar situations between reloading manuals. Some with great differences but most with slight differences. I have never had a good explanation given for the major differences. When I start with a new load (especially with a new bullet or cartridge) I always cross reference multiple manuals (I have most of them). My advice is to start with the minimum suggested load and work up carefully. There are so many variables involved; you don't want to take any chances. ~ SnapShot (Larry)

John: As with Larry I too have been at this hobby for quite awhile and also have a number of manuals with the same discrepancies between manuals. I have found the bullet manufacturer's to be more conservative than the powder folks with Sierra generally the most conservative.
I do load the .22 Hornet with the 45 gr 1210 bullet and have tried Lil'Gun in my Ruger 77 with erratic results, the velocities were high and erratic, I have not yet tried that powder in my No.1.
My start was 12 grs. ending at 13 grs. with WSR primers Winchester brass and no ill effects other than as mentioned. I don't think I'd start with Sierra's load though it seem too light given the others. As Larry said don't take chances and that goes for my comments as well! I'd call Hodgdon!

John,
I will echo what Larry and Bob stated. You are going to get those differences as to how each did their testing. Did they use a firearm or a test receiver. Of course the bullet people are testing their products. the powder companies test several bullet manufactures. Now if you can get a copy of Speer #14 manual they list for Lil'Gun start 12.0 and max of 13.0C and they use CCI 500 primers and that is small pistol primers. As with any load developement start at the low end and work up from there and be vigilant of pressure signs. Also John yes there can be differences in bullets as per how they are made. One may have a more sleek nose and also have a slight difference in bearing surface. Look at Hornady's 30 cal. 160gr FTX one is for the 30/30 the other for the 308 Marlin Express not only do the have the cannelure in different place the nose profile is also different between the two. So yes different bullets from certain manufactures will have varying pressure curves.

I received a reply from Rich at sierra today.
Hi John,
According to my sources you can use 12.0 to 13.0 grains in a 22 Hornet with either our 45 grain or 50 grain bullets.
Now that is a major departure from either data sources you quoted and mine is the Hodgdon Annual Manual. I don’t question the Hodgdon data so I’d go with that and use our 7.1 as a conservative start point to work up from if you have concerns.
Note that Hodgdon didn’t differentiate between 45 or 50 which is good. Lil’Gun is pretty well established as THE powder for the 22 Hornet but I do like H110.
I really don’t think either manual has a misprint but back when we did ours Lil’Gun was brand new and no one knew anything about it so when the big velocity numbers came up we assumed there were pressures as well which was not the case. While I know the Hornady bullet pushes a little harder than our ours I’m sure they ran into the same thing we did and played it safe knowing they could always go up in charges if necessary.

jb', thanks for the update. I too prefer the H 110 or the H 4227 however more testing is in order. The Li'Gun works very well in my .218 Bee.

My daughter came from Missouri, my son and grand son, my wife and I had a nice dinner of grilled "porter house" pork chops, corn on the cobb, my son, G'son and I share 10/5. G'son is 4 minutes early though @ 10/4.
Pooh I hope you find to right house .
