Does anyone make a device to simplify single loading for bench shooting? I use the SSAs in my CZ bolt rifles and find them very convenient to use. I'm not looking for a magazine that requires removing/replacing, but rather just a sled type of feeding device.
I would strongly recommend against this practice. I have made significant progress in building and determining the accuracy potential of the 1022 platform.
That said, it has been my very consistent experience that hand chambered rounds are the least accurate, recoil chambered rounds are much more accurate and consistent. It has become my practice to shoot the first round out of every magazine as a sighter when I am going for maximum accuracy, bull's-eye targets, or shooting for groups.
I know it sounds counterintuitive that there should be a difference between a hand charged/chambered round and one that was chambered by recoil of the rifle, but there is a distinct difference. I have tested this countless times through no less than seven proven rifles and can tell you unequivocally it is the truth - measured targets do not lie.
It is a simple matter to shoot the first round off target, as a sizing round or at the sighters, pull the magazine and top it off if you need to for round count.
I know it sounds like this process will waste some ammunition, and that is the truth. That being said, when you are trying to squeeze every thousandth of an inch out of these rifles - every little nuance in the shooting system and shooter will make a difference. This particular one is a no-brainer. Hand charged rounds tend to be the flyers in your groups and will be the most consistently inconsistent rounds you fire out of a 1022.
And with regard to magazines - I have also found that the BX 10 magazines do not produce the most accurate/reliable results out of my rifles. A properly tuned TI 25 magazine with it's four top set screws adjusted to properly set the magazine height and feed angle has produced the best results in my target rifles. I have been using them exclusively when going for maximum accuracy for two years now.
I am just sharing my experience here, and if you do not believe what I am saying, I would encourage you to move forward and experiment with this single shot idea but I think you will, in the end- come to the same conclusion I have - although it will cost you some money in ammo fired. If you do see this through to its fruition, please take the time to post your results back here for the benefit of all readers.
