All, I realize this is a reloading question and should be in the reloading section but I wanted to run a poll and did not see that option in that section so I apologize in advance. I am starting to work up a load in my new semi-custom savage 110 7mm rem mag with criterion 24 inch barrel 1:9 twist. The components will be 160 grain accubonds, IMR7828ssc, cci250s, remington brass. Because we cant do reloading at our range, I have to do load work-ups in stages. Here is where things got interesting. I went to the range to find my rifles max charge or until I hit book max (I do not like going over book max yet). I loaded up 7 charges and shot them at 100 yards with a chronograph. There was no horizontal dispersions and just a touch of vertical. Unfortunately I did not keep track of which charge created which bullet hole. So imagine a .5 inch drawn virtical line and that is what the bullet holes looked like all touching. Again, they were almost perfectly inline from left to right. I am thinking this means that at 100 yards, no matter what charge I pick, "may" lead to ragged holes (which is great!) I typically run OCW tests (only ran 3 to date) but all have provided me with great to decent loads for my applications. However, I do not think the OCW test at 100 yards would be of value here since, like I stated above, the groups may not very much from one charge weight to the next? So my thought is either running the OCW test at 200 yards or run a ladder at 300. I have heard ladders at 300 can be very unpredictable...too much opportunity for the shooter to mess things up. What do you all think I should do? My application will be finding a load that will be good to 500 yards on deer, which it looks like almost any of these loads will be well under 1 MOA and could work. Should I simply load several charges near max and take the best at 100/200 yards then verify at 200/300yards and call it good? Should I run 100 yard OCW, 200 yard OCW, or 300 yard ladder? Please leave comments below and I am sorry if this thread sounds dumb, just looking for ideas from you experienced shooters/reloaders. Note I will not be able to verify past 300 yards until next summer. I will not be shooting this rifle past 300 yards at deer until next year as well.
