Just a little dream

I have my AR15 in 300 whisper and I love it. The balance could be a little better, but over all I'm happy with it. So, with Florida talking about enacting a Firearms Freedom act, I'm getting the...

With a bolt action rifle, you will most likely need a finish reamer anyway to set the head space to your bolt. When I built my .308 bolt gun, I got a PTG (Pacific tool and gauge I think) reamer from...

I sighted it in at 20ft, then tried it at the range and couldn't find my laser dot. I dropped the crosshairs a full rotation of the knob, probably 40 or so MOA and still couldn't find it. I shot it...

H4227 and IMR 4227 are supposed to nearly identical in burn rate (m/s2 not just in the list). My Sierra manual has 221/300 load data back in the single shot pistol section, I had to adjust the...

Got a scope, need an idea for dial in.

I put my bore laser in, and the windage is on. How is the dwell on the 300? Will bore sighted elevation get me on paper at a 35 yard range? I only have 5 rounds built to try out 11gr of 4227 with...

Tried 4227 in my AR platform

I finally picked up some IMR 4227 as was suggested here. I couldn't find much in the loading data for it, but I found references of 9.8-15grs. I started low 10.0gr, the bullet lobbed toward the...

I may have some No 7 sitting around, but most of those seem like supersonic loads. Do you know of a link with more sub sonics?

Basically I just would like to find some ideas for starting loads...
