need advice on load work up for 338

Ok all here goes. Im trying to get the most out of my 338 edge. Ive always just loaded 92 grains h1000 and shot it.. Iam getting more serious than that now. I bought some new brass expanded and skim neck turned them. Uniformed primer pockets, debured flash hole weight sorted and used the ones that were all within a grain of each other.. I then bought a gem pro scale and used it to check the accuracy of my hornady electric power dropscale. Hornady lock load d dispencer thing?... got redding bushing dies. 364 bushing 363 bushing . Bought sinclair chamber depth guage. Ok heres where i am now. This is the part iam thinking about now. Oh i guess i better buy a ced m2 . I own a pro chrono thats always gave me readings. A pact that has never worked. Guess ill get a ced m2 .. ok back to where i was getting. Now should i lo ad up say 2 rounds at 89 grains two at 89.5 two at 90 and so on till i get to say 93. And shoot them at 500 yards and go down a look for accuracy nodes. Or should i load up the same and shoot them through a chrono and see witch one has the lowest es. Or should i load up 5 at 92grains touching lands 5 at 92grains 5 thousand off the lands 5 ten thousands. 5 20 thousand 5 30 thousand off 5the 40 thousand and 5 50 thousand. Shoot them at 300 yards through chrono and look at group ,and mv for lowest es. The bullet is a berger 300otm hybrid. I stoped chewing a year a ago. But man this is driving me crazy thinking i might start that bad habbit again. My wife and daughters are gona be upset with me. I had a guy build this gun for me and my wife never batted an eye because she said she was so proud of me and i deserved. It .. help please!!!!

Well i guess since nobody seems to have any advice. Ill load up 5 at 89 gains and 5the at 89.5 and so forth till i get to 92. Shoot them all through a chrono. And the ones that have the lowest es. Go from there . In smaller grain increment. Till i have the one with the lowest es. Then play with oal and see how that affects es. And go from there. Guess thats what iam gona do.. if somebody had anymore ideas iam all ears and would like to hear them.. thanks.

I had the best performance out of my 2- 338 edges with RL25 and 300 gr SMK. I had a lower ES, better velocity and accuracy than H1000. H1000 can be very inconsistent lot to lot.

Re: need advice on load work up for 338

Why are you so worried about ES? The only time that I use a chrono is to find out my avg velocity for my shooter app. Even after doing that, I still go verify my drops so I guess I just use the chrono to get me close.

Just load up some in different grain increments and go shoot them at whatever distance that you want (depends on how far out you shoot in the future). If you are not going to shoot past 500 yds then you can test at 100 or 200 yds and be fine. If you are going to shoot to 1k or further then you might try testing at 300 to 500 yds and see how they do.

If you haven't shot longrange very much then you can start out testing at 100 and take the best three loads and then test them out further.

In the end, the target, not a chrono, is goingtotell you which load is better. Don't get too stuck on ES. I have a rifle that shoots a load with avg ES of around 20 and it holds half MOA all the way to 700 yards.

Re: need advice on load work up for 338

Hi all. I loaded up 10 rounds at 90 grains and ten at 90.5 and ten at 91 and 91.5 and 92so and 92.5 today all the same length right to the lands ok iam planning on shooting monday. Thinking of setting up my prochrono because it works or at least gives me readings. And shooting these at say 600 . Yards . Should i set up chrono or just shoot and see witch has least amount of verticle spread. Then later shoot through chrono after ive found witch one has proformes the best. ? Any other ideas? Iam all ears ..
