"Blackout Contender" | A Few Groups from the T/C 300 Whisper Barrel

Great kit🎉

[@WilliamCChapin]

@@bigracer3867 Thanks! I just finished moving that T/C scope back to a Super 14 .223 barrel, and set the 300 Whisper up with a fixed 2x Weaver on a Leupold Dual Dovetail base. It’s been scope-swap day around here - I also changed around the setup on my 10” 221 Fireball barrel for 1/2 scale.

I think that’s an accurate summary of the video: A goofy guy makes fireballs with a flag in the background. 🙂

Looks like fun… need to get a rest for my 309JDJ SSK50 but was fun first 50.. making progress too

[@WilliamCChapin]

@@ewetho Super cool! Get ‘er dialed in!

[@ewetho]

@@WilliamCChapinhave you ever used Bellm oversized hinge pins? I have used them very effectively on my 5 Encores… this SSK50 and SSK barrel definitely has play when the Pachmayr forend is off. Got a pair coming….

[@WilliamCChapin]

@@ewetho I haven’t had a need for them. I do have one of the old adjustable collet style pin sets that came from my Dad’s stuff.

Hello Mr. Chapin! 🤛🏻🔫🇺🇸

@@viejo2a Good morning, Mr. Bunning! How’s the weather out there on the coast? We’re at 64 degrees headed for a clear and sunny 71, with an overnight low of 48. Early fall weather here…and it’s wonderful!

[@viejo2a]

@@WilliamCChapin clear and 60deg here at 8:30. Headed to the range right now 😀

18 to 20 gr of CFE blk does well for me with multiple bullet weights in the 300 . I think the powder case fill helps ?

[@WilliamCChapin]

It seems like case fill is a more significant detail than the powder charge size itself.

[@jamespollard1670]

@@WilliamCChapin For the most part , yes. I rarely work up loads anymore . I start 1 gr and 1/2 gr below max with a powder with good case fill . My hunting bullet loads are normally .6 and target bullet loads are .4 to .5 with this method . With cast bullet loads I settle for 1 moa as it's hard to get any good case fill with those . Some of those 1 1/2 moa are a struggle . Low case fill = higher ES most of the time

[@WilliamCChapin]

@@jamespollard1670 I should have specified that I was referring to CFE BLK specifically. I shoot other powders that are not at all fussy about case fill. CFE BLK is by far the most goofy, misbehaving powder that I have used. 🤪

[@jamespollard1670]

@@WilliamCChapin yes , it does misbehave with partial case fills I've noticed . Just like h110 can at times . But for cartridges like my 243 and others I can get ES's in the single digits with a good case fill even with a ball powder. I believe powder choice and case fill makes load development much easier if you want accuracy and good es .

[@WilliamCChapin]

@@jamespollard1670 I’d like to see the single digit ES in .243 with ball powder. 🤭
