Just wondering from everyone's experience were is the most accurate load most commonly found?? 10% down from max is were everyone usually starts. Do I really need to start that low?? With every gun that i have ever done load development for i started at 10% under max and worked my way up to max. My most accurate loads are always at 5% or 4% under max. Were does everyone else find there most accurate load at? I think from now on I'm going to start at 4% under max and if it's good I'll just stay there. if it's not good I'll try up or down 1%. Give me your opinions!!!!!!

please delete this thread!!

It varies greatly from gun to gun.I have found the best accuracy at the maximum load for several guns,and slightly reduced for others.If a load only produces good accuracy at 5% below maximum,I will usually try other loads.
 
The 300WM, showed pressure signs about 5% below max.

If it showed pressure signs you were well past the maximum load for that rifle.

When I refer to maximum loads,I am meaning the maximum load for that rifle ,determined by my load development,not the maximum load in the manual.The difference can be significant.
 
We've found it not only varies from gun to gun, but even more from calibre to calibre
Here's what I mean: I've had 2 300wm's. Both like it on the hotter side. On my wife's 30-30's(one bolt, one lever), a mid range load is by far more accurate with both 150 and 170gr leads of all makes tried.

Keep in mind when talking about max loads check different manuals. My standby is still my oldest(1956) manual, but I use the newest Lyman for some calibres.

I guess to answer your original question, I always start about 3/4 of the way up the suggested loads and go from there, but it's not always up.

Re read the replies mentioned, and gotta say, they both sound to me like they know what they're talking about, from experience.

Sure does not sound like it to me!!!

Max load for a particular gun will not be less than max load suggested by the manufacture of the gun powder!!! Unless there is something seriously wrong with the gun!! Powder manufactures do not want to hurt someone and get sued!!!! that is why the have a substantial FACTOR OF SAFETY!!!!!! They base there max loads on what the lowest quality guns can handle with out causing damage and than they still back it off from that point!!

Flat primers can occur at even 25% less powder than suggested maximum load!!!! Flat primer is not a sign of over pressure!! A primer with a hole blown rite through it is a sign of overpressure!! Over pressure is most commonly indicated by a horizontal circle rite at the top of the web!!!

A split case is also not a sign of overpressure unless it is split horizontally on the web. if it is a vertical split or a horizontal split further up the case it is from thinning due to the amount of times the brass is been reloaded!!! Lower load with a tighter chamber will of course allow more reloads than a higher pressure in a slack chamber!!

All I was asking was were do most people have the best luck. In other words how far under or over maximum suggested load to most people find the sweet spot for there rifles?? I was not asking for a bunch of crap about how to tell if your are over pressuring your rifle from someone who does not even know how to tell!!!! Such a simple questions does not require such a convoluted reply from someone who is trying to make them selves sound smart!!!
 
I am really starting to wounder if there is any point in asking questions on this web site because 95% of the people who try to answer them don't have a clue. The other 5% that know what there talking about don't voice there opinion because they get so sick of listening to the first 95% of the peoples bull#### that the get frustrated and say the hell with it!!!!!!
 
P.S. you start 3/4 of the way up the suggested max load?? Why would you start at 25% under max load!!!! your bullet cant even spin fast enough to stabilize it's self!! What a waste of time!!
 
I loaded my 308 cal Tika T3 with a range of powder from 45 to 47.3 grains of IMR4895 pushing 150gr SP interlocks from Hornady. All produced good groups, with often 2 holes touching at 100 yards, so I simply loaded up from then on with 45 grains only, figuring it would extend the life of the rifle and brass. The combination worked very well on Whitetails so all in all it was a loading success.

I'm currently spending a fair bit of effort trying to find a good load for my Ar15 with 75 gr Hornady match bullets. Can't seem to get anything to do better than 1 moa for 10 shots. Maybe I need a different bullet, but supplies are scarce.
 
here it comes!!! this is when i start to laugh!!! It's always funny when people start telling me that the Military explosive Expert sitting beside me is wrong. Maby you dogleg need to read a few more books!!!! If anyone at all on this website was held accountable for the even half bull#### they spread there would suddenly be very few people with opinions!!!!!

P.S. Factory ammunition is at maximum load!!!!!! Some factory ammunition is actually loaded higher than suggested maximum load such as Barrett 661gr FMJ M33BALL and guess what!!!! no overpressure!!!!!!!! if you can imagine that!!!!

If you have any worries on load methods , or other concerns, please use factory ammo...:D
