Switching to loose powder finally

[LCguy]

After another inconsistent day at the range, I am finally going to make the switch to loose powder. My groups with my CVA Wolf V2, T7 pellets and cheddite primers are always lights out (sub 1") at 50 yards with both Hornady Bore Drivers and Barnes Expander hollow points but always open way up at 100 yards. Are the groups still good enough to kill an elk or deer? Yes. Are they good enough for me? No. Especially since I drew a premium unit for elk. I drew the same hunt last year and had multiple opportunities at 300+ bulls.

So I am making the switch to loose powder. My local Cabelas always has Triple 7 FFG in stock so I will be using that. I'm open to different primers to try out. I only use the cheddite because a local gun shop has a ton in stock for cheap. My hope is to use the Barnes or Federal BOR Lok 350 gr. lead bullets for elk and the bore drivers for deer. I have killed a cow elk with bore drivers in the past but would like a more stout bullet for elk.

Anyone have a similar set up and have any tips/advice/load data to help out with?

What’s happening between 50 and 100 yards? Open sights? Shooter input?

Yes, using open sights. I'm getting around 4 inch groups at 100. I'm using a EABCO peep rib and a Williams front globe with the 0.019 green insert.

I'm sure there is some shooter input issues but I am usually pretty good about calling that out to myself before I even look down range. Obviously not perfect.

I'm hoping that maybe going down to 90 or 95 grains will really tighten the groups up.

I'm also curious if barrel temperature has anything to do with it? The last few times I've gone out it has been in the 80s to start and warming up to the mid-90s.

Sabots don’t like heat so you definitely need to let the barrel cool sufficiently.

As for the groups opening up - my bet is it’s the sights. Nothing magical happens between 50 and 100 yards. If youre consistently shooting ragged holes at 50, your 100 yard groups should be roughly twice as large.

Might try putting a cross hair insert in with the fiber optic sight. I will also try to be a little more disciplined with my shooting approach. Still going to give the loose powder a shot so I have more control over charges and velocities.

Definitely the way to go.

With T7 are you swabbing between shots? As a crud ring can lower accurancy, so keeping powder build up down is important & could also widen your longer range groups. As you did not mention your process between shots.
Just a thought.
