I've had some very slight hangfires in my .450 Dakota. Load was 405gr Rem SP over 92.0gr RL-15, Dakota max load (their data) is 105.0gr with 400gr bullet. When do you guys use a filler on the big stuff, what do you use, and where do you get it? Cheers, Andy | ||

What primer are you using. Should be Fed 215M. Some folks use kapok. The RL powders are double base, need good primer contact. All my experimenting shows it's much better to use RL-19 and fill case. Like 5 times better. Hangfires are scary business.Ed MZEE WA SIKU | |||

if it is under 80% you must use a filler opinions vary band of bubbas and STC hunting Club Information on Ammoguide about the416AR, 458AR, 470AR, 500AR What is an AR round? Case Drawings 416-458-470AR and 500AR. 476AR, http://www.weaponsmith.com | |||

My cut off point is 88%, or 7/8 fill. Little more margin, and there is the next slowest powder to make the space fill up.Ed. MZEE WA SIKU | |||

adrook Because the 450 No2 case is so big I must use a filler with ALL loads. So if you do decide to use a filler I recommend either dacron polyester pillow stuffing, or foam plugs cut out with a 50 BMG case. The filler MUST BE COMPRESSED between the bullet and the powder. I have fired over 3000 loads with fillers with no problems. DOUBLE RIFLE SHOOTERS SOCIETY | |||

Thanks everyone. Primer was Win Mag primer, have had a tough time getting Federal primers for the past year or so. I am going to try the filler. Cheers, Andy | |||

I use a filler ,pink foam board with my 700 nitro. I use 160 grains of Rel 15 and have had 100% ignition with it. | |||

Ed or Jeffe, How are you measuring the percentage of how full the case is? Do you fill it up with powder to where the end of the bullet would be and then weigh the powder and then calculate what the actual charge is as a fraction of total capacity? Cheers, Andy | |||

Andy- I always measure how much powder case holds to bottom of bullet.In grains. Then whatever load is I know the percentage of fill. Now straight cases are easy to make fillers for like above with the dense foam, like bigdoggy uses, or Like I use wads in 12GA FH or 16 ga wads in my 700HE. Dacron, tufting and other fillers work in necked cases. But as I mentioned if you doing 80-85% fill try next slower powder and load full. The slower powder will have a lesser and slower peak pressure, brass lasts longer.Ed. MZEE WA SIKU | |||

Under 90% of case volume use a filler. Dacron fiber seems to work very well.Hangfires are extremely dangerous. Seemy post on gun kabooms!

RL-15 is a position sensitive powder. In large cases it need to be held aginst the primer with either Dacron polyfil for Kynoch type foam plugs. Once you do this you will find that RL-15 will give you some of the most consistant velocities you have ever seen. It does in my 450/400 3 inch. Rusty We Band of Brothers!
