good to hear, I have 5 lbs of H4350 that I bought to try to use for this rifle.

H4350 is THE powder. Might want to also try Re17, H100V, RS-Hunter, Re19, H414

How are they as far as seating depth sensitivity goes? I have a box I haven't tried yet.

 

[hondo1312]

I don't really know. I use AICS mags, and the 140 Hybrid is a LONG bullet. I seated the longest bullets to 0.010 less than mag length, measured the base to ogive, and used that measurement for my initial load development. I THINK I'm jumping them about 0.065, and they shoot well at 100 (consistent 0.5ish MOA) and I had a 10-shot group at 600 that measured a hair over 0.6 MOA. I think the whole point of the Hybrids was to be less depth sensitive than the VLDs.

The hybrids are not as sensitive as the regular bergers from what I have found. I run my 140's .002 off the lands which has given me the best results in my rig. I have tried the hybrids from .002 off to .040 off and have done very well with them.
