currently using 35 grain vmax+ 12 gr lilgun, (.22 hornet) and want to try some sierra 40 grain heads, question is do i use same amount of powder? same seating depth, thanks in advance pb

No, a heavier bullet necessitates a reduction in charge to keep the pressure the same as the lighter bullet.
The proper load data is avalible on the Hogdon powder website: http://www.hodgdonreloading.com/data/rifle
Select "22 hornet", then "40 grains" then "lil gun".

"An infinite number of monkeys banging away at type writers for an infinite period of time will eventually reproduce Hamlet" Thanks to discussion forums we now know this to be untrue.
thanks for that,
scroll to the bottom for lil gun!
I have found personally the charge i use for 35 gr v max is also the best charge for 40 gr bullets but is seat them 15 thou longer, but as you're upping the weight i'd back off half to one grain and work up again to make sure the load is safe and also that you don't miss an accuracy node.
Edit: I've just noted you're using 12 gr under the 35s, this is minimum load anyway so start there and see how you get on, you may want to seat longer and you may want to get closer to the max (won't publish my load but its a lot higher than 12!)

Thanks for looking
Scott, you are not wrong in anything you've said but as the chap is a newbie perhaps he's better off sticking to factory data until he's been around a bit?
If he doesn't have a chronograph, for example, how is meant to know where max is?

Sorry buddy, I've just seen this, 12-13 is published data for a 40gr soft point I was agreeing with what you pointed out...
In terms of knowing where the published max is then its 13, for his rifle he needs to be watching for the obvious pressure signs set out in any good reloading manual.

Get the "one book/one calibre" booklet; "The complete reloading manual for the .22 hornet"
It has all the data from both bullet & powder manufactures for the given calibre rather than a manufacturer book which only gives one opinion.
Sierra say for #1200 .224" 40gn Hornet, lil gun - 9.2gn @2700fps, 10.6gn @2800fps, coal 1.720"
Note the data given above in post #2 is for the Speer bullet (Spire SP 40gn) which is why it says SPR SP (not SIE SP which is Sierra) seems Lord Flashpants can't read manufacturer abbreviation's

Hodgdon's data for lil gun is 12 min 13 max for all bullet weights bar the barnes 30 gr and 53gr (because they are long), so changing to bullets of similar style and weight shouldn't cause too many issues, if a 55gr is still 12-13 then a slightly different shaped 40gr soft point.
Thanks for looking
Yes, I know Hodgdon's info is all the same Scott, that's exactly why I use the one calibre book, because all the bullet manufacturers have different loads for their own bullets & from my tests they perform much better than just dumping in 12-13gns as per Hodgon's say so.
It's quite a jump from Sierra's recomended 9.2gn to Hodgdon's 13gn.
I'm pretty sure we had this same discussion when I first got the book

We did indeed!
mind you I shot a 4 shot 2.5" group at 300 yards in a 5 mph wind yesterday, 5th shot was a flier unfortunately by some way, that's getting 3100-3150 with a 40 gr tipped nosler varmint. At 100 yards they are giving 1/2 Moa and the load seems temperature stable as load testing was done at 1 degree, yesterday was 17-18 degrees and I had been a bit worried about getting pressure but had no signs.
I had 3 accuracy nodes giving 1/2 moa or less at 100 for 3 or 4 shots, all nearer Hogdgon's old max load than their current one ... and they're a massive jump from your load!
The only thing with 'one book one calibre' is unlike manufacturer's websites they are always going to be out of date data which puts me off, plus I'm loading 7 calibres now so it's cheaper to get information from manufacturers on the net making sure I cross reference 2 or 3 sources when deciding on a max load (with Guesty and his QL. As a back up for stuff I just can't find).
Edit. I'd best just add all the loads I mention are worked up safely and are safe in my rifle, they may not be in others I'm not suggesting anyone, experienced or otherwise, start off near current published maximum or exceeds it.

As per the point I made above (or tried to make) the OP asked about Sierra 40gn you're using Nosler 40gn ballistic tip & Nosler (like Speer) agree more or less with Hodgdon, with the book giving 11gn-13gn at 1.723" coal.
I agree a double check with the bullet manufacturers web site is always a good idea.
