Which Bullet in a 6mm Creedmore Gas gun? 105 or 109 Berger Hybrids?

[ReaperDriver]

I have a 6mm CM upper on order and 6 months out and I'm trying to stock up on components as I find them in stock. Are there any issues with shooting the 105 or 109 Berger Hybrids in a gas gun? Especially the 109s as I assume they are longer.

Are there any other bullets you guys are having really good success with in the 6CM? TIA.

My biggest concern would be running the 109s at mag length.

Is your barrel going to be throated so you aren't jumping too far?

I'd probably stock up on 105s if you can.

You can’t jump the 109s too far. They are very insensitive to seating depth.
