| What do you like or dislike about shooting compressed loads, such as are they more consistent or not? |

Lightly compressed loads are usually with the "optimum powder" and generate high velocity with good accuracy.

| I have to agree with 7mmmag to much compressing is trouble bulging brass and poor preforance, but if the load I want to use is to much for one case I will at times switch brands of case's in genral I find that R-P cases have less capasety than Winchester |

| Remember that case capacity will increase after the brass is fire formed to your chamber. New, unfired brass won't hold as much. I learned that the hard way after loading new brass with my full loads for hunting. MagPro in a 300 WSM at 76 grains is a compressed load. That much powder won't even fit in a new case. |

| Thanks for info, i have found that alot of reloader's really just want load a cartridge (none of them) to the max load period. While other's say compressed loads are the best. Though some cartridge's you never hardly see a compressed load listed for then on some about every load when at max is compressed so i was just curious! |

I rarely load compressed loads. In fact, most of the time I find, with most of my rifles, that I get the best accuracy a grain or two under maximum.

Also depends on powder. I compress Varget in all my loads and I still don't think it's enough. |

For bottleneck cartridges I follow a routine selecting powder and compressed loads is part of the routine.
1) I prefer extruded powders to ball powders as ball powders don't like to be compressed and may have unexpected pressure spikes when compressed.
2) I research which extruded powders have the lowest ballistic pressure with the highest velocity and offer the ability for 100% or greater loading density within safe ballistic pressure limits.
Don't listen to me, I have only been doing it this way for 50 years and my lifetime best is only a 5 shot 6.82 inch group at 1,000 yards.

I prefer compressed loads for accuracy, but working up is always necessary. Just because it's listed does not make it right in all rifles, the throat being the first variable.
I, too, prefer extruded powders, but single-base, as there are SOME double-base. The single-base tend to be some cooler-burning.
Too much compression will make many powders burn erratically, but as it's worked up, the accuracy and velocities will change, and you'll be able to see where the difference comes in.
Almost all my shooting is done over the chronograph, so it's easy for me to see when that happens.
Have fun,
