I'm new to the 6.5 CM bought some Nosler 130 gn accubonds and some IMR 4350. Whats a good powder charge for this combo? i kinds fucked up Last time and misread the load data and almost blew my dam rifle up . SMH so I come seeking knowledge . what say ?
Little help ?

Hodgdon thinks that powder is slightly slow for your bullet as it only has options for heavier bullets but I would start at 39 and work up in .5 gr increments to 43 gr, stopping when you encounter pressure.

No IMR 4350 but H4350 is close-ish

I typically grab a couple of different reloading manuals to compare powder charges and work my way up. As stated before every rifle is an individual and you must treat it as such. Even if you get a good load from somebody here, ALWAYS verify it with printed data as everybody can make a mistake.... I know that in my rifles I'm never able to get the velocities that many list here and just take it with a grain of salt.
I went to the nosler site but their data seems to start at 135 gn , cant find the data for 130"s
I have several diff. powders , IMR , VARET , AND WIN760. Not sure what to use.. First time loading larger cals. I just use cfe223 for my Ar15. but this Haus is a lil different . lol
What spife said.
Depending on how much shooting you want to do and information you want to gather in one trip.
I usually do at least 3each at .2 increments. Starting a couple below max into a couple above max. Run the chrono and shoot at small dot targets several per page on 8.5x11 cards. Labeling each group what the charge was. I'm looking for Velocities/groups/max pressure signs.
I can usually find a good enough load from that or at least have enough information I can come back and fine tune.
As a general rule your best consistency and accuracy will come from filling your cases close to 100% fill (load density). Other powders will work but look for the powder that best suits your bullet/powder combo. Load density is a general rule of thumb.
You should be able to access load data for free from most bullet and powder companies. If you can't find what you are looking for in the Nosler manual, check Sierra or Hornady. Just don't try starting anywhere near max loads, work your way up.
this is what i found on accurate shooter that i use to develope a load
there are many ways people use to develope their loads, this is just one way
always use common sense as you have a small bomb going off in front of your face
if you get it wrong you can guess what could go wrong
make sure you've read your reloading manual because the first part (many pages) of the manual will go through how to reload
- Find the lands by seating a bullet long on an empty piece of brass (no primer or powder).
- Chamber the round & close the bolt.
- Open the bolt & measure the base to ogive. Do it a few times to confirm.
- Load a known powder/primer/bullet combination. Load 4 of each powder charge in 0.5gr increments & seat bullets at -.020". Use one shot of each load & keep an eye for pressure signs. If you encounter pressure on the hotter rounds, don’t shoot groups with those loaded rounds & pull the bullets when you get home. Do not shoot in round robin style because position & natural point of aim will be compromised.
- Shoot 3 shot groups starting from lowest charge to highest charge & shoot all groups over a chronograph.
- Examine target & find the place where consecutive groups line up vertically & ES is the lowest & speed increases the least from one group to the next.
- Load to the middle of the found powder node & test seating depths.
- Load 3 shot groups starting from -0.005" all the way out to -.040" in .003" increments.
- When you find the seating depth test that shoots the best, load towards the longest side of the node to allow more room for throat erosion.
- Final step is to load the new seating depth & load 5 in 0.1gr increments 0.5gr on each side of node (if pressure limits are not reached). This will cover an entire grain of powder & you will be able to pinpoint where the powder node starts & ends. In the summer, load towards the low end of the node, & do the opposite in the winter.
