My father in law, father and I all recently bought each 300 ultra mags in the rem model 700 sps. Each has a leupold. We got together a month or so followed a break in procedure and now we are wanting to work up a load. next weekend we will get together again to shoot, so this week we all have the homework of loading some rounds to start with. we will also have the availability to reload at the same location that we will be shooting ( 5 minutes on the quad). We all hope to shoot H-1000 and the 200 grain accubond. we all have measured the col to max length based on mag length. I have read most of the posts on the subject and there is some really great info! I just wanted to run my summary by all of you to see if I missed anything or if any rounds could be saved by doing something different. 200 grain accubond & H-1000 step 1 89 grains (2 shots) 89.5 grains (2 shots) 90 grains (2 shots) 90.5 grains (2 shots) 91 grains (2 shots) 91.5 grains (2 shots) 92 grains (2 shots) = max load in book i am using total = 14 shots step 2 pick best two groups from step 1 and shoot a 5 shot group each? total= 10 shots step 3 pick best group from step 2 and load in .2 grain increments on either side of it and shoot these in 3 shot groups to find sweet spot? total = 6 shots total shots = 30 Not sure of what the rifles are capable of, but my question is? with this method should we able to find the best possible load for each rifle. or rather, is it likely? any help is greatlty appreciated. sorry so long of a post!
