Hornet K

[223AI]

Mines also a CZ 527 groups were not as tight with lighter loads 12-12.5-13gn but the 13.5 was a raged single hole.

got some done to try at 100-150yds when I get the chance.

I think I'd struggle to get more than 13 in the case, definitely wont get 13.5 in apparently rem brass is a bit more roomy and will take up to 14 grains of some powders.

Hmmmm k hornet reamer perhaps

Hmmmm k hornet reamer perhaps

or a different powder ?
H110 maybe, my book quotes 12.3gn as max load with 35gn V-max for 3100fps in a std case.

Yeah that's a good point, the hodgdon site gives the same weight for the max load for the 30 gainers out of the standard case, giving 3150 fps

Well I had a nice afternoon re-zeroing, having changed mounts to a weaver rail to get the correct eye relief, and It definitely seems to like the 30gn barns @ 13.5gn lilgun,
easy sub 1/2" groups at 50yds & 1" at 100yds. I suppose I ought to try some fine tuning at 0.1gn increments to see if I can get down to 1/2" at 100yds

Unfortunately the V-max 35gn @13.5gn were only doing 1.5" at 100yds so I guess a bit more testing of those is required.

I can see this rapidly becoming addictive

Too late !!!

Today I think I learned a loading lesson the "heart breaking" way

Having got "in the right area" with 13.5gn lilgun & a 30gn Barnes varmint grenade, I made up a batch of 5 each at 13.3gn/13.4gn/13.6gn/13.7gn to fine tune all using the same brand case to be accurate,

except that I found 1 case damaged so had to make the last 13.7gn in another brand.

tested at 100yds those 13.7gn just put 4 through the same hole with that (spit) odd case, 3mm off low right that would have been my first 100yd single hole.

So always batch load with the same brand of brass.

These Hornet are fussy little buggers ! Don't even try grouping on a full moon !

Even using the same brand from a different batch can make a difference, I have some RP Rem .233 brass that I reload with, I bought some once fired on SD, with the same charge they shoot about twice the size group. When I weighed them they're about 2 grains heavier empty so must be thicker.
