simple as it gets load data

8-)I’m going to try to make this short, neat, and thorough. Here is a load suggestion for almost every powder suitable for 10-ML use with the exception of the 4 factory listings (N110, Xmr-5744, Imr-4759, and Imr-4227) and Lil Gun. I excluded Lil Gun but only because the loads I would suggest would seem weak compared to what most want if they shoot this powder.

N120

250 grain bullet: 65-69 grains
300 grain bullet: 58-63 grains ( changed from 61-65 )
350 grain bullet: 58-62 grains
no other data

H and Imr-4198: Maximum loads should be reduced by 2 grains if shooting Imr-4198 data is for H-4198

250 grain bullet: 65 to 71 grains
300 grain bullet: 64 to 68 grains
350 grain bullet: 64 to 66 grains
400 grain bullet: 60 to 64 grains

Reloader #7
250 grain bullet: 64 to 69 grains
300 grain bullet: 60 to 65 grains
No other data

N130
250 grain bullet: 75 to 79 grains Note* perhaps a bit slow for this bullet.
300 grain bullet: 69 to 73 grains
350 grain bullet: 64 to 68 grains
no other data

10X

250 grain bullet: 74 to 78 grains
300 grain bullet: 71 to 75 grains
no other data

H322

250 grain bullet: 85 to 90 grains not recommended except to fast hard kickers
300 grain bullet: 72 to 78 grains
350 grain bullet: 70 to 74 grains
400 grain bullet: 66 to 70 grains

Xmr-2015 (very similar to H322)
250 grain bullet: 86 to 90 grains
300 grain bullet: 73 to 79 grains
350 grain bullet: 71 to 75 grains
400 grain bullet: 65 to 70 grains

Imr-3031
350 grain bullet: 77 to 80 grains
400 grain bullet: 73 to 76 grains
No other data

As with any load data there is a disclaimer: The only claim of validity is I have shot all these loads in my own 10-ML. None of the loads showed any sign of abnormal performance in MY rifle. Still if a load or any component is new always start 10% below maximum and work up.
