according to hornady's 10th... min charge for lil gun is 25.2 grains... with a max of 37.9 under the 250 ftx.
although like many folks, in my bushmaster 20" upper - as well as two others i've helped friends do load developement on (another bushy 20" and a BCA 18")... 38 grains is the sweet spot.
so while those min loads are relatively light, they shouldnt be anywhere in the range of dangerously low.

Long story short, 33.7 grains and 34.1 grains produced the best groups so far. I need to go up a bit on the charges as I'm getting a bit of soot at the mouth of the case. 33.7 grains yielded 2129 fps and grouped three into 1.003" at 75 yards. 34.1 averaged 2114 fps but only grouped three into 1.139". My replacement stock finally arrived that has the varmint weight barrel channel so the barrel is free floated all the way back to the barrel nut. The original stocks barrel channel was tight on the barrel even though I opened it up as much as I could. Groups should get even better now.

With the 250 Grain FTX, I continued to have sooting all the way up to 40.0 grains of LilGun. after that it diminished. After much research for all three of my 450 bushmaster‘s, I have found that 39.5-41.5 grains of Lil Gun is my sweet spot for most of the 250 grain pills from Speer deep curls to Hornady Shockwaves and the FTXs. A .474” taper crimp is good. Add the LeGendre side crimp to that taper crimp is even better.

No two 450b rifles are exactly the same so remember: YMMV
