[spence]

Bought a model 100 yesterday . Can I shoot military 7.62x51 ammo out of it?Can any owners give me a critque. are they any good? Thanks in advance . spence

Short answer, yes you can. But, I would advise staying away from steel case ammo. When practicing, I once had mine "double". A gunsmith who was well aquatinted with 100's told me not to very carefully touch off the shot. Use a firm press instead. They are a great rifle

Long answer, why would you? There is a reason we have .308 ammo and military 7.62 ammo. I believe the .308 chamber has less leade.

Research to see if it has had the recall done on it if you haven't already.

An older member of the gun club owned one of these Winchester 100’s. He sent it in for the firing pin fix and it still slamfired.

You can look at the diagram here:

And see that it looks as if the firing pin is not positively held back, there is a spring, but it sure looks as if there is the potential for a slamfire due to a sensitive primer.

This might be of interest.

This link claims slamfires were due to firing pin breakage. If you had a double, and your gun is not broke, it was either due to a sensitive primer, or you were not firmly holding your rifle and you tripped the trigger on recoil.

I don’t know what the firing pin modification was, I suspect it was a lighter firing pin. I would recommend, even if your rifle has the firing pin mod, to use the least sensitive primers on the market, which would be the “mil spec” CCI #34’s or Tula7.62. For factory ammunition I would look for ammunition that is made for the M1a. Federal makes ammunition that is appropriate for the M1a. http://www.federalpremium.com/products/details/rifle.aspx?id=809 The port pressure on this would be OK for your rifle and I have no doubt that Federal is using their mil spec primers in this ammunition. Federal has made their mil spec small rifle primer available to the public, because of all the AR15 slamfires, but to date, CCI is the only American manufacturer to release their mil spec primers.

I really like the 100's but if you ever need parts you are in trouble. Even with parts being nearly non-existent I would take a 100 over a 742 Remmy. If I could find a slick 284 that was priced right I would grab it in heartbeat.

What Captcurt had mentioned is right on. I happen to have a .284 and sorry no it will never be sold. It is my first big game rifle. I have found a number of sites that say they have parts for your .308 and the .243 version but the 284 is almost nonexistent. I've been looking for a second magazine for over two years. Mine still looks new compared to the ones I have found and they still want $75+ for them. I'm the second owner and the original owner never had the pin fixed, nor have I. Although the rifle has only had 60 rounds total down the tube in its life I keep reminding myself to have it done just to be safe.

I had a 88 and 100 in 308 and I understand about the mag. I had to pay $60 for an after market mag.

I forgot to mention the 490. It was a 22LR the same style as the 100. I should have my butt kicked for trading it.

A few suggestions:

1- Don't try to take it apart until AFTER you read the instructions.

2- Take good care of the bore, from what I've been told the barrels are pretty much non-replaceable.

3- Be very careful and deliberate when shooting your M-100 from the bench. Hold the trigger back after you fire and only release it after you've settled back down for another shot. That'll take care of 99% of the "doubling" problem. The only times that I've had it happen were when I first started doing load development shooting from a bench.

4- M1A magazines can be modified to work very reliably in an M-100 if you're good with welding and a file. Just make sure you start with a good magazine to begin with.
