Have any of y'all seen a significant degrade in accuracy in the modern inlines over a period of time? My CVA Accura was real squirrly last year on accuracy even though I clean everytime it's been shot (BH209 I might add). I'm considering dropping from 110 grains BH209 to 100 grains BH209 and maybe switch around sabots. Any tips?

Make sure bore is dry before loading and firing. I run an alcohol patch to remove residual oil or solvent.

Not familiar with your breechplug, but make sure the flash channel is free of carbon and flame orafice is not eroded to a large diameter. It can and will happen with BH209, just takes longer than smokeless.

I own 3 breech plugs and swap them out frequently while I deep clean the others.

Last year was the first year I left my muzzleloader "loaded" between hunts. I wonder if I was getting condensation issues even though I shoot BH 209.

BH209 is non-hydroscopic, it will not absorb any moisture in its unburned state. The residue it leaves after combustion will, hence barrels rusting after firing and left uncleaned.

Not sure what's causing your grouping issues. Somebody else will chime in I'm sure.

bad scope, loose mounts, even a loose stock screw will really mess up accuracy.

Whats your current load set up?

I have a Bushnell Elite 3200 with Burris rings and mount. I don't think its the rings or mount. I'm considering dropping down to 100 grains and trying the Barnes TMZ 250 grain.

Current load:

CVA Accura (Original without Speed Breech plug)

110 grains BH209

300 grain Harvester Scorpion PT Gold

Federal 209A primers

Bushnell Elite 3200

Burris rings with the aligner cups in the ring to ensure 100% contact

Drop your powder to about 60 grains and just shoot a 3 shot group for a test. If its good you are using too much powder. If not you have a bad scope. Muzzleloaders are very hard on scopes.

My encore shoots 100 grains of BH 209 better than 110 grains ,so I guess every gun has a sweet spot.

no way with 60 grains, thats just a plinking load.

100-110 grains BH209 will be the key for accuracy with the 300gr PT Gold.

One thing I would do, jb bore paste the bore about 50 to 75 strokes, changing patches every 25 strokes, clean that out, light oil " no bore butter!" swab bore once with a dry patch to mop up excess oil and before shooting it next time out, an alcohol patch to remove oil.

3mm or #32 drill bit to remove carbon from breech plugs flash channel, that really can mess with a guys group when it hasnt been cleaned.

Loose stock bolt possibly.

If it shoots a couple shots decently and then goes all over the place after that, its a bad scope.

I didn't say to hunt with it now did I? That's just my starting load to check accuracy then you can increase powder in 5 grain increments until accuracy suffers. But I have killed several with 60 grains way back in the day.
