help

bought a new t/c triumph with a cabelas scope yesterday.
I Shot it today but could not get it sighted in, gun seemed to have a mind of its own. Cabelas said my load of 110 grains of pyrodex with 295 grain powerbelts was too light, need more powder or less bullet. Does this sound like a solution or a bad scope?

Re: help

Yes I started at 25 yards with marginal results. The screws were very tight. I've never had an in-line before, but heard thier accuracy is good.

Re: help

Bull on the too light. If anything I would say you are pushing that particular bullet too hard. Start with 80 grains of Pyrodex and the 295. Are you shooting aero tips or hollowpoints? What's the load doing? Are you grouping at all? We need a bit more data.

Re: help

It's probably 1/28 twist at least; Maybe 1/24 twist; don't know offhand about TC Triumph. A 295 grain powerbelt probably won't group very well from that twist unless charge level is very low. They don't group well in my 1/28 twist even down to 80 grains which is where I gave up on them. Try at least a 348 grain Powerbelt or a saboted bullet at least 240 grains. Take the scope off until you get something that groups and then put it back on.

Re: help

I had no group at all even at 25 yards. What is the difference between a sabot and powerbelts?

Re: help

110 grains and that bullet are an elephant load, a fair amount of being in excess of white tail loads.

Re: help

In the end that bullet may just not work in that gun. But first a few checks before giving up on it. Did you notice if the holes in the target were perfectly round indicating stability or lack of? I use the PB 295 AT and HP in my flinter (1:32) with 90gr of 3F 777 and get very good accuracy. That dosn't mean you will in your gun but from a charge perspective I think we are probably very close. I think pyrodex is very close volume wise to real black 2F so my 90 of 3F 777 is probably pretty close to your 110 of pyro, add 10% for the 777 and then some more for the 3F granulation, must be real close to a 110 pyro charge.

How easy or hard is it to load? Hard? if you're using the 295 Aerotip what ramrod tip are you using, any chance you're deforming the tip? Easy? any chance the bullet is moving off the charge because it is too loose? Should be a firm push, not hard or easy.

Re: help

I shot a lot of different loads in my .50 Triumph, with pellet powder, loose powder, sabot bullets, and powerbelts but the best combination for my gun has been 100grs.(2 pellets) of Triple Seven Powder and 250 gr. T/C Shockwave Bonded Bullets (blue nose) with SuperGlide (yellow) sabots. Very accurate especially if I swab the barrel between shots. Makes loading easier, too. Good luck with yours.
