Are those loads on those charts max, how many gr down do you go down from to start with,4gr enough?

if you know the twist rate of your barrel, the length of your barrel and your muzzle velocity go to the site and run the numbers JBM
Barrel is .22" I will get the twist rate from Winchester site. Thanks for the help Mucko.

If I do happen to get to split necks or or discoloration in the brass how much do you back off?
VIVA LA HOWA
Split necks is a chamber,die, brass thing rather than load. Brass work hardens. It stretches out to the chamber is squeezed in by a die and if full length stretched out again to final size.
Anealing can prolong case life in this instance .

308Win One chambering to rule them all.
Show's how much I know, That's what you guys are for until that bloody book gets its ass here. So How do you know your loading too hot?
VIVA LA HOWA
burns your finger
Google search what ejector marks, cratered primers and flattened primers look like , they are your most basic and easily noticed pressure signs. it all depends what brass your using. I have only ever had split necks in my 204 and that is from brass fatigue I believe, they have been reloaded many times.
if you are loading the 300wsm buy norma brass. it is just over $100 for 50 pieces and is far superior to winchester at not much greater cost.
when developing loads I usually increase in .5 increments 2.5 grains below stated max. if I still haven't found decent accuracy and haven't seen pressure signs I will push past max a few grains until accuracy improves orppressure signs appear.
reloading is not by any means difficult and is only as complicated as you want to make it. just make sure you do everything right the first time and get into good habits, checking and checking again.
Oh thanks for that tip about brass. How many reloads do you average per shell?
VIVA LA HOWA
with my 204 I'm using hornady brass which I have found to be terribly inconsistent in weight but don't really care as i can still get .2-.3 inch groups with it. they have only been neck sized and have been loaded 8 or more times.
I have loaded my wsm brass 3 times with only neck sizing. I expect to get 7? reloads.... I really don't no how many i will get.
Oh yeah cool thanks. would 6.5x55 and .308 last a little longer then wsm?
VIVA LA HOWA
if your only neck sizing they will last a long time. even with full length sizing they will last a long time. I have never used the 6.5 so can't really comment. buy quality brass and you will be rewarded with consistency and durability. you will probably loose your brass before you wear it out haha
I have 3 batches of 300 RUM brass that is VERY different in weight - spent time weighing etc, then shot a mixed bunch with no difference in groups
I'm not convinced brass weight is of any real concern (providing you dont have massive differences in internal volume), where as neck tension is a priority
