What do you think about the look of that Bullet Chris ?http://www.mattsbullets.com/index.php?main_page=product_info&cPath=66&products_id=198&zenid=0d8uthkkdr4dgns01cmrl90a14
My concern is that the slug may not have enough steam behind it to stabilize from impact to exit. Maybe a tuned .50 DC could swing it....maybe not. 700+fps wouldn be fast enough I'm sure.My tuned 909 doesn't have the power of a 909S, but when I shoot 270+grain WFN thru it velocity goes way, way down. I shot an old plank of wood about 2 inches thick with my 909 with a to-heavy 270+grain WFN, and then with an EPP/UG. The to heavy WFN stopped sideways in the middle of the plank, while the EPP/UG plowed thru clean. I'm sure a 240grainWFN would have plowed thru fine.....my rifle just appears to meet diminished returns shooting boolits over about 260 or so grains.

Butcher, I am not quite sure I understand what you are saying there in the part I highlighted. Are you saying that for each caliber you think there is a minimum acceptable velocity for hunting, no matter what the FPE or weight? And I guess that velocity might change with what you were hunting and how tough they are? Sounds like it can get a little complex?? I know some guys like to keep the velocity above 850 all the time anyway just to reduce the hold-over concerns.Care to expand a little?Thanks,Lloyd
....................For now I'll ask: why did the slow 270grain WFN wind-up sideways, and get out-penetrated by a faster 154grain?
The longer a Conical Bullet is ,The better it is on being Stabilized
Could it also be that the 270 gr. was long enough to not be stabilized by the rifling.....Bob
Rsterne, Good point Bob, The longer a Conical Bullet is ,The better it is on being Stabilized. Also I think A conical is stabilized by the rifling also. The longer & Heaver A Conical, The more Stable. A heavy Conical Bullet is effective on game even when the velocities are relatively slower than a light bullet. A Lighter Bullet may have higher velocity and therefore greater muzzle energy than a Conical, However it will also shed that energy much faster. The momentum of the heavier Conical allows it to shed its energy much slower. That same momentum retention remains when the Bullet strikes big game. A combination of Bullet Weight, Diameter and Velocity are Key, And important to increases both penetration and trauma to an animal. Conical Bullets also have many Disadvantages, The more weight in the projectile ,The more Energy needed to get it started down the Rifle barrel. Conical Bullets can only be made so short before it becomes unstable. I know Butcher knows all the factors that have a role in the De-Stabilizing of Lead Conical Bullets. All the information Butcher has passed on to me has been Rock Solid , Butcher knows his stuff. We are all lucky Butcher and many others are there for us when we need advice. His knowledge He & Others pass on is Very Well Valued IMO. The Veteran Big Bore Air Gunners on the GTA Big Bore Gate are the Best Around for All Pertinent Big Bore Air Gun Questions. However sometimes, Some of the Super Technical Answers such as ones in Physics and Stuff are a bit mindblowing to me and usually takes me a couple of times to read it to have it sink in. IMO,There is no Question nor has there been one that could not be Answered here. Jetman
