Re: soot on necks
"Soft load" is a pressure denotation. What powder,bullet and how much of each are you using the recipe?
There's no shame in not knowing something. Though it'll get ugly if you try to feign same.
A headspace analogy is thus...picture a Mason canning jar painted black,with it's threaded lid as your rifle's chamber. It's contents being your 22-250 brass. When sized in accordance,the brass enters the jar with but slight resistance to the lid,as it becomes fully seated into place. In that manner you could literally shake the entire jar and all would be static,less any sound transmitted by internal movement. That is positive headspace,which was determined very obviously by feel,as the lid sealed things. You've made a perfect fit.
Now full length size that same hull,retighten the lid and give 'er a shake. You will hear "clunk-clunk-clunk" and that is excessive headspace. Problem is,you don't know how big of a "clunk" you are dealing with,because nothing was done in increments to establish same.
Never make a "clunk" any louder than you have to,to assure reliable feed/function. That will promote much increased caselife and bolster Precision in conjunction.
Savvy?
