Re: Huge Disadvantage with Internal Magazine?
Much is going to depend on the way the match is setup.
When time limits are short and targets plentiful a top-loader is going to be an issue.
Keep in mind I still own a couple and strive to run them to their limit. There are a couple tricks to maximizing a top-loader.
The first is practice. You need to be able to drop a round in the loading port without breaking position. If you can't do that, you are screwed. Train to do everything with your cheek glued to the rifle and your eyes looking downrange.
Second, you need a stock pack with ammo loops, a Redman Ammo Card or something similar stuck to the stock. You need ammo close at hand and oriented the correct way. When I can stay prone for the whole stage, I open one of my Ammo Burritos and pre-stage the cartridges partially out of the loops. This allows me to grab them quickly and not fight with boxes, carriers, etc.
If you fumble a round and drop it, forget it. It's gone. You will spend more time trying to pick it up then you will just slamming another one in. If you fish for it, you will run out of time.
Run what's in your magazine and then single load the rest. This is KEY. The only time you should stop and load the magazine again is if you are ABSOLUTELY sure that you have enough time to finish the stage firing all the rounds in the magazine. Wasting time putting rounds into the magazine that you will not fire is stupid. If you practice, single loading is FAR faster than pressing that round into the magazine.
If you blow the reload, don't waste time unfucking the rounds in the magazine. Dump the floorplate and drive on. I have watched guys blow their allotted time trying to correct a round when they could have dumped the mag and at least gotten a couple downrange single loading.
Given the choice, in a big match I will always take the removable magazine rifle. If it's not a long range match or requiring razors edge precision, I am beginning to lean more towards the AR10. It has been seeing more and more of the local matches because the accuracy is only slightly less than some of my bolt guns and the speed is amazing when you learn to really drive it.
