Good info. I do know that a LOT of people shoot factory ammunition. Those who do, do little shooting, I assume. I started handloading with my first 3 CF rifles, every one of them, back in the late 1960's.
The first factory ammo I purchased, was just about 10 years ago, for a trial, for a new Browning .300 mag. I already had been handloading .300 mag. for it and wanted to test the new WW 180gr. bonded ammunition. It shot identically to my handloads, clover-leafs at 100 meters.
Just a few years ago, I bought another box of factory ammo, for a new-to-me 30/06 M70, that was made in September of 1936. This was also 180gr. bonded WW ammo. Seems to me, it was around $30.00 for that 20rounds. It shot around an inch, whereas the handloads, in that "old" rifle, do just over .6" for 5 rounds.
Just last Saturday, I checked the pricing of ammo in .45/70. I was quite shocked to see it was from $70.00 to $85.00. YIKES - for 20 rounds.
Then, I saw a box of 50 350gr. FN bullets for handloading, was $82.99 & 325gr. were $80.00 for 50 bullets.
Yikes again.
Good thing I cast for the big bores and have a decent stock of smaller bullets for the smaller ones - for handloading.
