Yes, Precision Shooting
is an excellent magazine - Precision Shooting Magazine - Welcome
While it doesn't state it, I believe they will sell you a back issue so you can get a feel for the pub prior to putting up the $37/year. AND, they have a LOT of relevant books for sale.
There is also an online pub from the UK - Target Shooter
The Fifty Caliber Shooters Association (FCSA) also has a great, professionally done pub - but you need to become a member to get it (or pay a lot for back issues)...and, of course, it is focused towards folks shooting 50 BMG-type rifles. That noted, there is a lot of transfer for ERL shooters below 50 cal. They'll send you a current issue for a look-see ($2.95 for S&H) Fifty Caliber Shooters Association
- read about half way down the home page (this link).
There is also a semi-pub that is one of the best you will find - AccurateShooter.com Bulletin

Have fun - its addictive!
