I tried for a long time with no luck, of course, my background is in writing (English major here). I do have a little freelance work lined up for an online gun magazine.

I was an English major too, and it's a tough market.
There are a lot of tech writers out there in places like India working for nothing. And, there are a lot of unemployed with years of experience in lean manufacturing and ISO processes applying to anyone and everyone.
So, your work is cut out for you.
I'd try to get an internship. Figure out which manufacturer is your dream company and then make a secondary and tertiary tier of choices to whom you would apply.
It also can't be said enough that you need to network and press the flesh. Go to the SHOT show, if you can afford it, and get to know some people in the industry. Get their cards, make an impression, and stay in touch by e-mail or social media and even hand write them letters (a very big deal nowadays).
My dream gig is to work for a large company like Ruger, or Honda's North American motorcycle division. 10 years after college, and I'm still beating on the doors trying to get my foot in just a bit.
My wife works in HR for a very big health care firm. Taking tips from her has been a big help for me in pursuit of a dream position in firearms. I'm not there yet, but I'm now using more successful methods to get and keep attention of significant people in key organizations.
