Greets all!

First, let me apologize, this has probably been cussed and discussed in this forum but I did a search or two on working up a load and didn't find the answers I need. I am not completly sure I need to do anything at all yet.

I have been hunting with aT/C Omegaforless than 14 months, this is my first blackpowder experience. Normally Ishoottwo50 grainpellets of777 and 250grain Shockwaves, and can keep 1.5 inch groups at 100 yards.

I would normally think that a lighter bullet, say 200 Grain and higher powder load would produce a flatter trajectory, hence more accuracy. However, I have been talking to a few folks and it has been suggested I check a heavier sabot, 300 Gr plus, and start with 90 grains of loose.

I have never been around anyone working a custom load for their rifle, soonly have hearsay and conjecture to go on.

I will probably never shoot in any competitions or anything like that and cant really gripe about the accuracy I am getting. Would this be a waste of time and energy?

Why would a heavier bullet produce a better shot group?

Is using a chronograph essential for this? If so hopefully they arent too expensive.

I understand why a heavier bullet could have more downrange Kinetic Energy,but not the accuracy thing. Also it would seem to me that a lighter bullet with higher muzzel velocity would tend to balance out the heavy weight but slower bullet.

In working up a load for my Omega, if I pursue it,it would be helpful if I dont have to completely reinvent the wheel, just fine tune it a bit.

Looking to hear from some of the more experienced than me. Oh, that would be just about everyone here.

Thanks in advance for your responses.
