hey folk. so i have a new cva accura... sold my optima v1 last spring. i posted recently and you all suggested i either shim or use o-rings to eliminate blowback... but on to a new issue.. here is what im currently shooting... cci 209M blackhorn 209 - 100 grains HARVESTOR CRUSH RIB SABOTS(green) Hornady 44Cal .430"Dia PISTOL BULLETS 240 GR HP XTP right now im getting 3" groups at 100 yards, and 6+ at 200. im set up on sandbags, and im a reasonably capable shooter, so im pretty confident that the problem is not me. i have a vortex diamondback 4-12 im swapping on to it to eliminate the possibility that it is the hardware(currently using a cabelas 3-9 powderhorn). but beyond that, what do you all think i should start with to tighten up my groups? will the o-rings do much? if not, i was thinking the rib sabots might be too loose for the blackhorn? i have some non ribbed green HARVESTER PREMIUM SABOT that i have laying around. im not sure if those would seal up any better... or if i should go straight for something else. i have limited time to spend at the range, and a limited amount of time before the season, so id like to try to figure out what might have the best chance of fixing my groups. maybe i should drop/raise the powder? am i way off on the bullet weight? the other concern is all of my knowledge on inlines is adaptations from what ive learned with my flintlock, and a bit of what ive picked up searching forums... so random inline/muzzleloader pointers that could be affecting my groups might be helpful to. some thoughts that i have... at the range, should i be reloading the gun immediately after firing, or will the heat and residue from the previous shot introduce moisture into the new load and cause inconsistent shots? when hunting, should i toss the unused primer that i pull out at the end of the day? im just learning about headspace and primer crushing and all that jazz. ive typically tossed the primer to the side to use the next day. should i be drying the barrel or anything before reloading after the last clean? aka, i clean today... next month i go to the range... should i be swabbing out the protective oil? ive seen folk say that they fire a primer down the barrel to pre foul the barrel for a good seal, ive seen others say they do not. i could always save the discarded unused primers from hunting that i mentioned above. ive seen people speak about the importance of cleaning the flash channel with a drillbit. now often does this need to be done? between every shot, or after cleaning? how about the flash hole? thanks everyone!
