i need your best guestimate on a load
as i am doubting the velocity numbers im getting on my older chrony, i would appreciate some educated estimates on a load im using. .44 magnum, 16.0 grs. of blue dot, 180 gr. jhp ( rem. bulk )..im using a 7.5" barrel..i realize data will vary some between guns, just looking for a ball park figure here please..thanks

That is a very low weight for blue dot in a 44 mag. My manuals give a starting load of 17.8 gr. I would guess velocity would be around 1100 fps. If you are wanting a light load, I would use something like Unique. I would be afraid that that light a load of Blue Dot would be very erratic. Blue Dot is very temperature sensitive, especialy to cold weather. 0 -
pear..for what its worth..the hornady manual gives a starting load of 11.2 grs using their xtp in that weight with blue dot.... 0 -
I have an older Hornady manual and it shows 16.6 gr with a 200 gr bullet. It does not list a 180gr bullet. Lyman no 47 is the one that I got the 17.8 gr starting load. 0 -
When you model this through a ballistics program, the following information is derived.
16 grains of Blue dot w/ 180 gr. JHP and a 7.5" barrel.
1300 FPS. (rounded off)
17,200 PSI. (top pressure is 36,000 PSI)
80.2% of powder burned. (20% of powder wasted)
** This is with a 180 gr. Sierra JHC confirmed with my Sierra reloading manual **

Alliant's web site lists 19 gr for 180 gr bullets at a velocity of 1725 with a 5.7 inch barrel.
