  1. Anyone know how big a jump the velocity would change as a result of temperature change, particularly those using win 231 What I am after is if I have a load that produces a 990 fps on a 40 S&W 180gr projectile during winter at 8 degress, Will the velocity go up when outside temperatures are say 36-38 degress?
  2. out of curiousity - do you all cant the gun or retain upright when shooting weakhand? I just find that I hit the target more consistently when canting. How about elbows, stiff arms straight or bent?
  3. I also noticed that the new projectiles I have has a diameter of 0.3995 which is slightly slimmer that the CMJs I was used to which was 0.400 but when I tried to load dummy rounds the crimped them to a diameter at the lip of the case at 0.420, I could press the projectile by hand and the bullet would slip right into the case. So I had to adjust my crimp which is now 0.418. What crimp measurement do you have?
  4. By switching - does your OAL change like mine or I suppose both your 180 and 200 have the same profile and therefore no need to adjust the seating die? I am using a 2011 STI pistol and a Dillon square deal.
  5. I have been using win231 and an OAL of 1.169 on a CMJ FP 180gr which produced a power factor of 175, suitable of IPSC standard division. I had to change the bullets due to low stock to a FMJ FP 180 gr and without changing anything on my press, as I am hoping to get the CMJs once they become available, I noticed that the OAL has reduced to 1.149 and I believe this has caused the spike in my velocity reaching 1,030 fps or a power factor of 185. I am thinking not to adjust my press so that when I get back to the CMJs it will be back to the OAL of 1.169 and I once again have my match ammo ready. I guess the angle of how the Flat point on the FMJ is causing this to seat more deeper thus creating higher pressures. Question is this 1. Is it safe to run a 40 S&W at 1030 fps resulting to a power factor of 185 or is this going to beat up the gun badly therefore maybe I should just dial the powder less?
  6. I have seek tungsten sleeved barrels from Akai pistols too
  7. So a "tungsten sleeved barrel" is not weight attached to barrel?
  8. I havent had your experience of a nose dive but I made it a ritual (at least someone told me), to load the mag full and let it sit for a few days for the spring to "normalize" and then start use. My MBX mags work well on my STI Edge and DVC. At first I had problems seating it on the Edge for some weird reason it just wont catch on the magazine catch - but it sort of sorted itself out after persistently trying several times.
  9. That looks interesting - So you just used a dremel I suppose. Did it take long - is this hardened?
  10. oh, how I had a brain fart.... When I saw your reply - it was Aha! your right.... I will do that - I did have it screwed all the way in and the trigger shoe is hitting the mag release button even before the bow could get to the sear. Thanks.
  11. Hi Idaho shooter, I am having the same issue with my xline trigger. What exactly did you do so that I can replicate it?
  12. question please on the X line triggers. I have a DVC and was changing over the trigger to the x-line and thought I would do that without changing any other part. Fitted the trigger into the plastic grip and installed. To my dismay the bow is either angled incorrectly or too short as when I depress the trigger, even with the overtravel stop adjusted loosely so that it does not get in the way, the gun would not fire. It is not able to reach long enough to activate the sear I think. I give it 3 times strong pull on the trigger and the it finally drops the hammer to the half cock notch only...and I tell myself what the ....... is going on. Repeated the whole thing and same thing always happens. Put back the old trigger and it works like a charm with no hitches. So, these x-line triggers appear to be - non drop in - in a way that the bow does not appear to be correctly angled.... Sorry but am I missing anything here ?
  13. this one was a strong hand only stage (requiring one foot on a platform behind target) and you can shoot pretty much on the side. I tried to keep shots deliberate here but left most target had an Alpha and a Mike, Second from the left is an Alpha and a Mike, third and fourth target had two Charlies each. - I cant believe I missed them.... I will look at how the sights are when dryfiring next. I wouldnt say I was rushing to the next targets on this stage but still having Mikes - had literally zero'd this stage. Trying to see where I'd go wrong to improve.
  14. So I did a bit of dryfire and noticeably draw from the holster and pulling the trigger, I see my front sight marginally moving left. when shooting strong hand only - it is magnified now with first shot on A zone and the second no where to be seen.
