I've had an apex since they came out with them.  At 100 yds with 110gr  Blackhorn 209, I shot a 3/4" group. I used to be able to shoot 1-1/2 groups at 200 yds.  Went to the range, and 100 yd accuracy was great.  I shot 3 shots, and it shot the same as before. I moved to the 200 yd. target, and was clear off the paper. I shoot powerbelt 250 Aerolites. I thought there may be plastic build up in the bore from the tail section of the projectile.  I sprayed the bore with plastic cleaner and then scrubbed it really good, thinking the plastic is the problem. I just wondered why the loss of accuracy so sudden. Anyone else encounter this? I have not shot it since I cleaned it to really know.

Check the base mount. I purchased an Apex that had the flat bar for the base and multiple pieces for the rings. After a couple of years and many shots working up loads for different bullet and just experimenting the base became loose. I ordered a Durasight Dead-On from CVA to replace it. haven't had a problem since.

Could very well be the scope/ scope mounts. One other thing is the breech plug. Depending on how many shots are through it, the flash hole could very well be worn out to the point its causing poor accuracy. I'd start with the simple stuff like checking the scope base/mount screws and then replace the breech plug.

FG, how many thousandths off factory spec does the flash hole need to enlarge before you start losing accuracy Question

thats a good question Marty. I honestly could not answer it and be right but mileage will vary with charges used, pressures from the sabot/bullet pressure, a lot of things come into play on how many shots you can fire before its kaput.

Before BH209 always recommended a .035" flash hole for best results. Now it seems, anything over .035" is worn out LOL. Its just one of those deals when your accuracy goes south, take a look at the plug as its a lot cheaper to replace than going through scopes and resighting.

well, did not have to worry about real long range accuracy this year.  I missed a trotting coyote, then crunched a doe at a little over 100 yds. Aerolite went exactly where the crosshairs were.  I guess I can't complain.  It all could have been me.

I met a gunsmith that builds ML's on rem actions last week. So my Apex, and new never fired Nitride Accura may be on the butchering block.  Wait and see, Kicking it around.
