CZ527 22 Hornet - Bobsled/Single Shot Magazine
Got my CZ527 bobsled today for my 22 Hornet. Looks a decent, simple bit of kit. I can now load rounds longer than 1.730" which is max mag length for the standard mag.
Bought some 40gr V-Max and measured the cartridge length to the lands. Turned be 1.918". Loaded x20 40gr V-Max 10thou less using 12.4 - 13gr of Lil' Gun. Looking forward to seeing how they perform.
When I was last out testing loads I had decent results using the Hornet specific 40gr Sierra SP with 13gr of Lil Gun. Measured these to the lands and found that they touched at 1.800" so I loaded four rounds at 1.790" to see if i can improve on things.
With the 35gr V-Max I'm getting decent results with 12.5gr of Lil Gun with a COAL of 1.729" but I think I may be able to improve on this too. These touch the lands at 1.777" so I may experiment with OAL from 1.739" - 1.777" using the same powder charge and see how I get on.
I'm kind of hoping I can get a good load developed with the 40gr ammo, preferably the V-Max, due to the increase in BC. I find the 35gr V-Max get blown off course quite easily.
Should be fun
