Rock Island BBR 3.10 .45 ACP range test !

Very windy and chilly day but went down to the range to try out this little beast 1911. Before I left home I put the slide in the mill and opened up the rear sight about .040 for more light around the front sight.
So the ammo to use was Fiocchi 230 gr. for factory loads... my 230 gr Xtreme loads using 6.0 Unique.... and my 230 XTP load with 6.5 Unique.
Ran 6-8 rounds of each load thru the 10 and 13 round mags and could see right off the 13 round Para mag will need the stronger spring as the rounds did not want to feed well. The spring in this one is weaker feeling that the factory 10 round mag and I have a spring coming.
The factory magazine worked fine with the factory ammo and my 230 Xtreme loads. However the beast did not want to eat the 230 XTP loads with a jam one right after another and will have to look into that.
Sights were not adjusted from the way they came and looks like no adjust needed! The pistol shot and handled very well without excess jumping around like I have heard. No issue with anything hurting my hand and could fire off multiple quick rounds on the steel.
I also wanted to test penetration in the ballistic gel with the XTP bullet since the barrel being a bit shorter than my Springfield XDE and the porting can slow down optimum bullet speed. That test revealed that with a bit less expansion at a reduced speed it traveled thru the 16 inch gel block and hit the wood behind and bounced back into the gel block. Looks good to me with that ragged looking bullet!
So very pleased with how the BBR performed and will see what needs to be done to get the XTP bullet to feed. Would have shot more today but that cold wind started to really get up and that was a head wind from my shooting position.
