I seem to hit a wall at about 1,275 fps no matter what powder and primer combo I use...

No doubt, but I had hopes of at least somewhere over 1,300 fps...

Can't help myself, just gotta "see what I'll do".... Whether its a gun, a car, a motorcycle, a horse, or a go cart... Lol.

And miss all the fun!

Hahaha, two heads are better than one.

I've about done all I'm gonna do on it for a while, I'm just not getting the speed I wanted out of the copper bullets... So they're on the shelf for the time being, until I decide to maybe try some 800x.

I'm back to the 200 grain XTP's and 12.6 grains of AA #9.... But I've switched to CCI 350 primers for all loads using #9... Decreases the compression issue a little.

Also, see my thread on modifying the RCBS seating stem so the XTP's can be seated without damage.

Loaded 3 at 8.5 grains of Blue Dot just to see where I'm at in the load data, since I'm using the mag primers.

They chrono'd 1,075 fps from the 7 inch barrel and sooted the case mouth a bit, indicating a very mild load and incomplete powder burn.

Gonna try 9 grains next...

Blue Dot spiked pretty good at 9.5 grains (1,170 fps)... No smiles, but VERY flat primers... Spooked me.

I stopped there and backed up and retested  Longshot with the new chrono and the 20# spring...

9 grains of Longshot, CCI 300 primer...1,286 fps at 25 feet... That is 1,305 fps at the muzzle and no signs of pressure anywhere. Primers look good, brass looks good, case head measurements are all within spec.

I am gonna try 9.2 grains again, just to double check to see if I still get the slight smiles with the 20 pound spring....
