increments

when working up a load i normal go by half grain increments. maybe it was just the rifles i had but is there really going to be much difference between say 42.5 and 42.7? (just and example)

Now your diggin' where the 'tators are!

Re: increments

Probably not noticeable in most factory guns. Keep in mind though, it will be noticeable in say a 223, not so much in an ultra mag. Case volume plays an important role. In custom guns it will definitely effect accuracy, things as small as different primer manufacture's will impact accuracy

Re: increments

There could be. I use to spend a lot of time shooting groups and sometimes went to as small a difference as .1 or .2 of a grain. Now I do not have the time, money or patience to do it in most circumstances.

Now I look for a group that will do what I need it to do.

There are more variables in primers, powder lots and case capacity that will affect group size than one or two tenths of a grain.

But then just sometimes you just have to make that hole smaller!

Re: increments

depends on the rifle you are loading for. for the larger caliber rifles one tenth of a grain wont make much difference, but calibers like the 204 a couple tenths of a grain will.

Re: increments

I am also in the camp where I don't worry about increments much under 1/2gr when loading stuff like my 300H&H where I'm throwing 72gr of powder, or my 264WM that gets 76gr.

My 204 I might....although that rifle is so NOT fussy, it probably doesn't matter. It shoots factory ammo into one hole, so once I start reloading for it, I'm not sure if I'll need to get that picky with it.

Re: increments

what kind of H&H do you have? mine is an old Remington 721 300 H&H. I load it with 66.5 grains of 4350 and 165 grain hornadys btsp. shoots great and will drop a deer in its tracks.

A prewar pre64 Model 70.

I load 72gr RL22 and a 180gr Nosler Partition, averages about 3015fps at the muzzle and does a number on deer.
