35.0 grains of Lil gun seems a lower than normal charge. Risk of pressure events (detonation)
XTPs are not engineered for the pressures required in the 450 Bushmaster.
1:16 twist? 1:24 twist? The 1:16 twists are going to stress the crap out of non mag XTP jackets.
Would the working pressures be too low to cycle the bolt carrier consistently?
In most of my observations here and from other members experiences, I am predicting you’ll not get the performance and cycling dependability out of your load.
I have the 1:24 twist rate out of a 16 inch barrel carbine length gas system.
Thanks guys I'll play with that load. At 36 grains I was getting good results on paper I'd thought I'd drop it down just to see.
I suppose there is one way to find out how these will perform. All else fails I get rifle rated bullets and use these for targets what a shame though.
