What about a 7-300 Norma imp?
I am running the 195s at 3125 from a 26" BartleinThose of you that shoot a 28 Nosler what velocities are you seeing with the 180's and 195's?
As for those folks in the magazine articles... Until they've shot a .300 Ackley with a 215 Hybrid...they'll keep thinking the .300WM is the standard.

I use new Nosler .300 Weatherby brass to form for mine. Works perfect, and there's literally ZERO prep work that needs to be done. No trimming, no nothing. Just load a starting load powder charge, and fire. Fire-forming is as easy as loading for a standard SAAMI case. Because it's a belted magnum, the case headspaces off the belt. So you don't have to seat the bullets into the lands to get a perfectly formed case (like you have to do with non-belted wildcats). So fire-forming cases for it, as as simple as can be.What's the parent case of the 300 ackley?
What speed are you getting with the 300ackley running the 215's, what barrel, powder, COAL etcAs for those folks in the magazine articles... Until they've shot a .300 Ackley with a 215 Hybrid...they'll keep thinking the .300WM is the standard.

Between 3,000-3,100 average. That was with 7828 SSC, but I'm going to try IMR 7977 and see if I can get some more out of it with less pressure. COAL will vary depending on how your reamer is cut (this is a wildcat, so there is no SAAMI standard specs). Barrel is a 6-groove 26" fluted stainless sendero/Rem Varmint 1:10 twist.What speed are you getting with the 300ackley running the 215's, what barrel, powder, COAL etc
300 win 28"+ with a brake.
Have it chambered with this reamer and you will be very pleased

I keep hearing this exact response, but it never gets elaborated on as to exactly WHAT or WHY that reason is...There is a Reason the 300 win mag is used as the golden Standard...
