I have Wolff 4.5 springs in all of mine and have never had a reset or a light strike issue.

Are you asking about the 124 grn. TC Match Winner?

Yes, in short order.

No issues. N320 is somewhat slower than it used to be out of all my guns.

Yes, I used to buy them in bulk until I tried the RMR bullet. They are excellent.

After trying every "gun oil" on the market I have settled on Amzoil 75W-90 weight synthetic gear oil. It does not thicken when in very cold conditions, it stays where you put it, it does not evaporate in heat or in time. It provides a superior lubrication in all climates for all things firearms related. A quart of it used with a needle oiler will last for many years and so far it has shown me less wear and better lubrication than anything else I have tried.

If it's the same diameter above and below the crimp line and the bullet does not move forward under recoil go with it.

I'd give it another half a turn just to make sure. LOL!

Since the edges of the primers are still nice and round that is not a high pressure sign. Flattened and cratered primers would be a different story. As others have said, it's the hole in the breach face causing this. Just shoot um.

Be very careful not to over crimp plated bullets. This is 99% of the people who hate them because over crimping them reduces their diameter resulting in bad accuracy and or tumbling. You can get away with over crimping jacketed bullets because the jacket will spring back considerably but the plating will not. Over crimping will produce a bullet that is under sized in the forward portion of the bullet so only the tail end of the bullet catches the rifling properly and the bullet will simply rattle down the bore. This will result in terrible accuracy and in the worst case tumbling. You only want to straighten the case, any further and you will have a bad experience. Pull a bullet, if there is a ring around it formed at the case mouth you went too far. I use them with great success but it took me a while to figure this out. I get match accuracy out of Everglades and X-treme bullets but you will need to work at it to find the magic spot on the crimping die. My load consists of 3.3 of N-320 @ 1.080 OAL for a velocity of 880 FPS with these flat nosed bullets. Using the STI you will be able to load longer. I choose the short OAL so they work in all of my guns.

Yep, this is normal.

The safety plunger hole was the culprit on mine. They sent me a replacement slide but it had the same issue. I reamed and polished the plunger hole and that cured the issue.

I use them because they are THE most accurate bullets I have tried in the last 45 years in all of my CZ competition guns. They are reasonably priced, quickly shipped, make a clear round hole and provide match grade accuracy. They are also available when most others are in back order and the customer service is A-1.

Plated bullets of the same weight will always be faster than the copper jacketed RMR Match Winners. Plated bullets offer much less resistance to the rifling than the much tougher copper jacket. Deeper seating produces more pressure therefore a higher power factor. I use 124 RMR Match Winners exclusively in my CZ's and get the same results as you do with N320 or SP.
