Is the performance jump that great that it's worth it? I can easily get the replacement breech plug if it is for next year.
There is no great performance increase with BH209. You can get the same velocities with 777 it just takes a little bit more powder or an extra pellet.
I'm getting about the same velocity with 105 grains BH209 (by volume) as I did with 130 grains of 777 pellets (two 50 gr and one 30 gr).
The advantages of BH209 is it doesn't deteriorate and lose accuracy ... 777 does.
And there's no swabbing required between rounds.
Some folks claim to get better accuracy with BH209 but a lot of that has to do with BH209 being loose powder. It gives you the ability to try different powder charges to dial it in.
At 75 yards none of this is going to matter except the ease of loading a follow up shot.
