Interesting to know, that powder was labeled as a 6.5 Creedmoor powder when it came out. H4350 was tough to come by then and a lot of people went to the other new IMR powder 4451 because it was similar to 4350.

4166 is good with the 120's and lighter in the 6.5 creedmoor.. kinda comparable to varget .i use it in a 243 with a 75 gr. Bullet.. and have used it with a 107 gr tmk in the 6.5 creedmoor.. both shot well and gave good speed in them applications..

Plan on shooting Stabal 6.5 loads tomorrow in my 7mm-08 improved.

Obviously from it's name it's a ball powder, it's very fine as in leaks out of the powder measure on my auto thrower. Pours well though and settles very nicely allowing more powder to be used.

I'll have some velocity numbers soon.

Hello all

Issues with the following setup: Hornady Case, Alliant RL16 and Hornady SST 129gr

The minimum OAL recommended from Alliant's data is 2.825in.
http://alliantpowder.com/reloaders/powderlist.aspx?page=/reloaders/powderlist.aspx&type=1&powderid=41&cartridge=184

With that OAL the bullet is not fully seated according to the markings on the neck of the SST bullet.



If the markings on the bullet was met then the OAL would be 2.7". At that point there is little movement inside the cartridge for the 44.4gr of powder to move.

Please help with a suggestion.

I wouldnt worry about that crimp line on the bullet.. it doesnt have to be seated that deep.. alliants recommended oal is just that.. a recommended seating depth.. myself i like to know what the oal is to the lands.. or more importantly what the cbto is to the lands.. then back off that .020 and start my load development..

Just a thought, should the oal be measured from the "tip/end" of the bullet? Or should I be measuring the oal from the ogive using a Bullet Comparator set to zero on the calliper?


Thanks

Base to ogive is what most use.. there can be a few thousandths difference from the ogive to the tip of a bullet.. so if you measure bullets from base to tip there can be some difference in length that probably isnt there when measuring from the base to ogive on the bullet.. its good practice to log both measurements though..
