I am by far not an expert on this. However, the ones I cut I like to cut from the base of the tree or 6-8" below ground level, as near the base is where the compressed wood usually is & the fiddleback & nice wavy grain of lots of them. Also you can get some nice grain thru the crotch areas & off large limb forks too.
I like to quartersaw mine to get the best looking grain if the log is large enough, but will slab it if not large enough. If it is not at least 24" in dia at the base it is too small for me to mess with other than to cut into 1" slabe. Past practice has had me trying to make something from nothing with small logs & it ends up with inferior wood & allot of wasted time for a gunstock blank. (IMHO)
I cut all the planks large, well over 6' and usually 7' & over 3" thick so I have plenty to work with. If the blank doesn't show a natural curve in it for the wrist area when I saw it, I don't waste my time & just slice it into 1" planks as it is furniture wood.
You can figure drying at least 1" per year in a dry storage area (depending on you humidity in the area), weighted down well & slated every 1' and the ends sealed with wax. I prefer to get the stock down between 10-15% moisture before I cut the stock blank out of the plank as you will have less chance of warpage. I want around 8% moisture content for a stock.
I have about 12 large planks drying now & there are 2 to 4 stocks in each plank as they are quite large & several of them 9' long. If I get 6 acceptable stocks that I will use it will be unusual, however, I am picky about them. The rest I will saw to furniture grade lumber. Normally I would just buy blanks but I only gave $100. for the walnut tree & a friend has a sawmill & sawed the planks for me for free, so not a big loss if I don't get any from it..
Note, I have been kinda stingy with it at times, trying to cut thinner blanks, this has proven to be an error on me because of shrinkage & it limits you to what stock you can make because of the cheekpiece & the cast off/on & etc. So now I go over 3" to make sure I have enough. If I was cutting for a Doublebarrel flinter or something like that, I would cut it 3 1/2 to 3 3/4 to give me a lil room.
I am sure there are lots of ways of doing this, this is just a amateurs way of doing it.
PS: You say grain is not important because of the stain you will use, however, grain thru the lock & wrist area IS important to have a strong wrist & lock area. Otherwise a few years from now you may have a large copper patch wrapped around the wrist. To me, grain structure at the lock & wrist come First on any blank I buy, then I look at the stripes, fiddleback, density, color, or whatever.
