I am surprised that all deer stalkers who have access to stalking ground dont have an improvised range where they can practice. I am lucky enough to have a number of places i can stalk and all but one have some form of basic flat bit where i can pop out a target, and we have ranges from 50 to 300 meters to practice on. In most cases it is just an old cardboard box with a stone in it and a printed target taped to it. Like many have mentioned here, i refresh the basic skills using quiet .22 rimfire or an air rifle if noise is an issue. I have spent many a summer afternoon, when any sensible deer is resting up, practicing and testing kit to make sure it suits my requitements. We have good rabbit numbers and the skills can be practiced when reducing the rabbit numbers on the base of the hill, and harvesting them for our game pies. In the largely heather hill and forested enviroment most of my stalking is done on this is done with the longest harris bipod, so it goes down to 9 inches for prone shots to 27 inches (from memory) for sitting shots. This covers probably 75% of my shooting and the full height is needed to get above the rank heather. I have a BT scope and have tested this set up many times at 100, 200, 250 and 300 meters and the BT is bang on, i just need to make sure i get my bit right and we normally aim to stalk to the most stable point we can find, often moving a little to get the right base so we are properly stable. I added in the 250 meter zero point as this became my nemisis range, and without the 250 BT zero i was struggling on some targets, the drop between 200 and 300 was considerable and so i needed the extra drop point, now i find it easy again. In addition i use the 5 leg viperflex sticks, they are the most solid platform i have tried and can be used for zeroing. They are required for some shots and we (my wee stalking group of pals) have all practiced at the 100, 200, 250 and 300 meter improvised ranges. I think all of us have 20-45 years of experience stalking with centre fires and still enjoy a day on our ranges, not just when someone has changed a scope or had a miss or poor shot, but also just when we have some spare time on a stalking day or trip. Its part of the enjoyment for us, and if we have planned a mornings stalking or a day out, and have harvested what we want in a couple of hours then it is fine to spend a little of the allocated time just checking everything is still bang on
