Troubleshooting Globe sights on Strikefire LDR

[zmellott0722]

I’m fairly new to inline muzzleloaders and am having a hard time getting my new Strikefire LDR to zero at 100 with a Western Williams Precision Sight.

Issue - Shooting 10” at 100 and have no room for elevation adjustment.

Grouping at 100 is fairly tight. Think a soda can

Shooting BH209 with 250gr Thor Hammer bullet

Attempted Solutions

-I have replaced the stock rear slider with a lower slider as recommended by Williams.
-I have experimented with different volumes of BH209 (95-110).. This makes a difference but only 2-3” per 5 grain by volume. I am hesitant to continue to lower powder by volume for an elk setup.
-I have shot 250 grain Thors and 300 grain Thors. This makes little difference.

Any thoughts on how to further bring this down?

Shim the front globe up a little.

And…IMO, 250 gr Thors are too light for elk - I’d definitely use the 300s.

There is an online calculator for how much to raise or lower front sights and rear sights. Helps take out the guesswork.

Will give that a try.

Worried about this as well. I will be using the 300 grain.
