Tried 2.75" Nitro Gold Rems once and after no more than 5 loadings they were cracked and burnt junk with 7/8 oz. light loads........
I have been shooting 2.5" hulls ALSO in 2.75" LC Smiths with over 20 reloads per hull.......that's all the proof I need........and I shoot every day............
Sorry, again you are not reading and comprehending Larry....here, for your easy review........
The Nitro Gold 2.75 " were tried in 2.5" chambers...just to clarify..........the mouths cracked and were burned as they folded partially out into the cones........every one.....rounds reloaded and fired numerous times for a total of about 500....maximum on some were 5 loadings....some less.....
Plastic residue formed in the bore from the shot wad as it was forced through the cone with part of the hull already there, excessive plastic in my opinion.....what it did to pressure, who knows...........I discontinued the experiment permanently and forever...........
No Larry, I have NEVER been in favor of shooting long hulls in short chambers, just tried it as mentioned above.......
The 20 loadings per hull are 2.5" cases in 2.75" chambers.....
I don't even load 2.75" anymore in any gauge.....if I need a heavy load for my Baretta's I use factory ammo, I still have several cases of Eley Grand Prix's which are not available in the states anymore...........
And Yes, there is some magic always........and my weird unique loading techniques........
