T/C Black Diamond Problems

[Jason S]

Bought a new gun this year to go along with my Sidelock 54 and the pair of Austin Hellecks that I have.

It was a T/C Black Diamond NOT the XR model though. Had always heard great things about T/C's guns and I liked how light weight it was compared to my other three.

It doesn't shoot good though. I can throw round balls out of that 54 that absolutely put the T/C's groups to shame and not to mention how nice my A&H's shoot. So I have ruled me out of the equation because of being able to group my other guns. I have tried real BP (ffg and fffg Geox), 777 (fffg and ffg) and Pyrdoex RS in it from 80gr up to 120gr. Bullets (all all lead per my states rules) tried so far are 340 PR Bullet Dead Centers, 300 PR Bullet QT's, 375 Buffalo Bullet sabots, Great Plains 385gr and 405gr, and Powerbelts 295gr, 348gr and 405gr.

First off had to replace the factory sights with Truglow just to get it to have enough range of adjustment to bring the point of impact high enough. Now best I can do at 50yds is about 6" groups. My A&H's are one hole guns at the same range with the same sights on them. The stock seems to not fit the barrel and action correctly and does not seem to be stiff enough. You can flex the forarm up and it moves a lot. The barrel is free floated from about forward of the recoil lug under the barrel from disassembling it. The only ignition system I have used with it has been CCI Magnum #11 caps.

Like the little gun and want to get it to work. Would be a nice primary weapon if I can get it down to abouta 2" group open sights at 50yds. Have had it on the range many times and still won't do it. When I finally think I have it the next range session it will have lost it's point of impact totally.

Any suggestions before this thing goes back to T/C with a flaming letter about it not shooting well at all.

I really do not know what to tell you.. I have a T/C Black Diamond XR and it shoots about anything I want to shove down the barrel real well. Have you tried to shoot the 250 grain Shockwaves? And are you swabbing between shots? Also the XTP's shoot very well out of my BD. Like I said, if you are working your loads, swabbing, I just do not know what it could be. If you call T/C they will tell you to try the Shockwave.

When you shoot conicals, are you using small powder charges. 80 grains is plenty for them when you shoot conicals. Then again, I do not have the 22" barrel version.

[Jason S]

Always swab between shots. One wet windex patch both sides followed by two dry patches and two caps rpior to next shot. Same I do in my other guns (except the 54 where I clean when accuracy goes away).

I can't shoot shockwaves as they must be an all lead design by law to hunt with here in Washington. Was hoping to get it to shoot with the 340 PR Bullets as that what I useto hunt my other guns.

T/C did tell me to send it back I probably will.

[cayugad]

it will be interesting to see what they find out. I shoot a 460 grain conical out of mine with excellent results.



That was with a scoped BDXR.

Amen, if you tried all those load and bullets and swabbing/not swabbing and you still did not get accuracy, something is wrong with that particular rifle. Sent it back let them figure it out.

Those are all longer & heavierbullets thatcould beharder to stabilize. Why not trysome of the shorter & lighter bullets, 225 to 250 grains with 240 being among the most popular?
Also,it's claimed that whena sabot sticks too long tothe bullet in flightit can throw accuracyoff. Have you ever tried the TC Break-O-Way or other brands of sabots?

[frontier gander]

If the stock is that flexy, thats more than likely your problem. Just send it back and have them take care of it.

[RugerMike]

These were TC's version of a single bolt and free floating the barrel on a muzzleloader 99% of the time they don't work because everyone holds a gun different on these synthetic whichs pushes the bullets everywhich away. I have fixed several of these by bedding the stock so there is no flex in them. (yes there are exceptions as always!) Muzzleloaders are a different animals and free floating isn't the way to go on them, with their heavy barrels that don't heat up like tapered rifled barrels. Either bed it or shim it to make it consitent and it will shoot one whole lot better groups for you. I have been keeping count and to date I have made 31 happy customers with this advice. If your works out ok, please let me know. Thanks Mike. Happy Holidays to you and yours>>
