Got the chrono out to test some polymer reloads and compare to factory loads.
Using "friends" Sig P226 (4.4" barrel), GL 17 (4.48'' barrel), GL 17 (4.48'' barrel w/ comp) and GL 19 (4.01" barrel)
Hogden says I should be getting 1075 fps w/3.9 gr and 1151 fps w/ max 4.3 gr w/ 4" barrel.with 115 gr LRN and TiteGroup.
I'm using 4.0 gr so I should be around 1094 fps.
Test with 4.4+" barrels
comparable 115 gr Seller Beloit 1140-1170 fps
comparable 147 gr Remington Golden Sabre 968-999 fps
Reload 116 gr polymer LRN w/4. TiteGroup 1200 fps
Test done using GL 19 (4.01" barrel) all fps was about 30-40 fps less than above but reloads still faster w/ less powder as per Hogden
The polymer coating adds 1 gr weight but because it fits a bit tighter in the brass, I'm getting a bit more (100 fps) "oomph".
50-75 fps ain't much but thoughts ?
