Re: Tuning a Load?
WOW! alot of opinions and a little tiff to boot. I more than likely don't have the experiance of many here on this forum but I'll drop a little input of my knowledge. You asked for a 1 moa senerio. In my experiance of the distance reloading game such as loading for a friend and you can only get together once in a while, which I have do alot of, falls down to this.
Think practicial choose 1-3 powders I usuall only use 2. If this is a common load it usualy can be found easily. something that gets close to filling up the case, produces a tolerable pressure and produces plenty of velocity.
Use the best brass that you can and prepare it the best you can.
Now you done that and you have a 1 inch group. assmuing this group is in a circuliar shape, as opposed to in a line, I would go with this load the next thing I would do is fiddle with the seating depth start at one end or the other, I prefer to start on or near the lands and start working it deeperin the case a little at a time.
The last thing I do is piddle with the primer selection although I have come to see over the years that remington primers are as consistant as I have found." hopefully I won't be attacked" I do not like federal primers especially the 215 unless you are trying to lite wet saw dust. I gennerally load for cartridges of the norm like 300wm or wby. I have loaded bigger but found the remington 9 1/2 M work more consistant. with most slow powders even AA8700 and retumbo but I have not loaded any BMG powder so I can' t make a comment. I use alot of reloader 22 and hodgen H-1000 and the remingtons always end up the best for me.
One last tip. If you have or can get a wilson seater and an arbor press you can load up several at full length and just push them down a little as you go.
I hope this helps you never know when an idea jars a better one loose.
Have fun with your load developing.
