Thread: Kimber Load Development

So here's the 7mm08 5 shot group



1 was the clean bore shot. For reference all load development in my kimbers is down allowing 1 minute between shots as this is most relevant to me as I care what a cold bore does. I don't clean between hunts I leave the bore fouled and just rush a dry bore snake through before and after a hunt. Once I sort a load I do usually do a 3 shot group with about 10 second between each shot (just however long it takes to set back up without rushing like you would with a follow up shot on an animal) to give me an idea of what to expect if I ever needed to use the whole magazine. (I try to avoid this though as by 3 shots the barrels warm and I don't like to burn barrels).

Here's the 280s 10 round ladder mainly just looking for velocity nodes on the labradar but interestingly they often line up with groups on paper.



Rifle wasnt sighted in at all do #1 was a slighter then after #2 I adjusted 6 clicks (1.5 Swaro MOA or 1.5648inchs at 107 yards this is shown by the circle I drew to represent its adjusted point in the ladder. As you can see a pretty good 4 shot group between shot 2 and 5 (1.5 grains difference). I did hit pressure signs at 6 with a marginal swipe that didn't occur at load 6 but returned for in shots 7-10 not sticky bolt lift or any other signs showed except a significant jump in velocity at load 10 I feel comfortable that in this setup a node between load 2-5 will be fine.
