Home Forums Hunting & Shooting Hunting Rifles Winchester 100 308

A sample size of 1 isn't statistically significant out of a universe of 262,838.

Fair enough. How about six?

My probability and statistics professor at Northeastern University, Bob Parsons, taught us that the smallest statistically significant number in a random sample is 30. A random sample size of 30 will get you on the target, more than 30 is dialing in the zero.

I've probably owned 15 or so Winchester 100s over the past 40 years, not enough to be statistically significant. The only problems that I had with Winchester 100s was that the 284 magazines would work fine in some rifles and not work well in other, it drove me nuts and it prompted me to quit on the 284s. The 243/308 magazines have all worked fine if they weren't damaged.

With over a quarter millions of them made, there were bound to be some lemons in the basket.

So here is an issue that my 100 exhibits from time to time. After firing three rounds, the last one fails to eject. When I pull it out, the spent cartridge is COLD, indicating there was no gas present to eject (the other two that ejected corrclty are VERY hot). I do have a spare gas gizmo...

I have a 22LR that is a dead ringer for a 100. Winchester, I think it is a model 490 if my old brain is still workin. It has been a good one.

FYI
I have a set of Pachmeyer pivot mount base/rings that fit model 88 and 100 if anyone is interested.

Back in the '60's when we all hunted out of deer camps that drove deer for one another, a M100 .308 carbine seemed to be just the ticket. Aside from it being a little fat around the grip, the mushy trigger and my lack of lubrication knowledge with WD40 gummed mine up, that little carbine always worked pretty well even with handloads. I seem to remember that it didn't do too badly at the range either. We had an old curmudgeon range officer who took every opportunity to tell me what a pos I had there. Probably a Redneck relative, but respectable 100 yard groups stifled him somewhat. Growing up shooting 870 and 1100's made me think that an early Tootsie Roll forearm 742 carbine would be better. Both those carbines have been replaced by one and done bolt actions, but they did the job when we thought our hunting methods needed them.

I have 2 Winchester 100s, one in 308 and the other in 284 Winchester. The only caution I'd mention is in taking it apart for cleaning, know the correct procedure. The action rods are easily bent if you don't pay attention. One of mine needed the new firing pin which was no problem to get from Winchester. Both shoot really well and I have had no problems at all with reliable function. If I come across a deal on one in 243 or 358, I'll likely add it to my accumulation...
