With 3031 I would think 2850 to 2900 would be close to the top end with a 25" barrel. I will run some loads in QL.

Bore size. Is 3500fps realistic? Drop Jeff can get 3800 out of my .452 350gr, so I guess a .40 cal 225 gr at 3500 is doable. The problem lies with the fact that not everyone shoots a bullet at the same velocity. Furthermore what one person considers to be bullet failure the other considers to be bullet success. A 3500 fps .40 cal bullet that doesn't blow apart might have to have a .040" thick jacket or more. That bullet might as well be a FMJ for guys shooting low velocity. Designing an accurate bullet for killing paper and deer is a balancing act. I'm trying my best for you guys! |

Kyle, Good luck with the tight rope - balancing act , I'm sure whatever you come up will be worth the wait for all of us.!!! Very interested to see the finished product, I'm of the "killing deer" camp. |

I would think you could push them to 2800-2900 ft/sec. Some might push them a little faster some may be slower. Accuracy is what is important.
Waiting to see what you come up with Kyle

How fast can we push it? Drop Russ..... I plan on pushing my 325 40 cal at or above 3800... Speed kills...... |

I'm talking about pushing the 325 that fast ? Will you build another gun like your Cyclops ?

You should cross section a 200gr SST. Ive heard the jacket is pretty thick already. IMO more mass is going to be just as important as a thick jacket, maybe more so. Its a shame Hornady never made the 200gr in a bonded jacket or a 40cal 225-240gr.

Just cut one a couple of days ago. Base, including first 1/4" of bearing surface is .045"
Remaining bearing surface and starting into the ogive is .035" The nose is .025"
They do some strange things above 3000fps.
I won't hunt with them again unless I slow them down.

How's these bullets coming? I should have my custom 40 cal barrel together in about 2 months or less and would love to do some testing.

I won't hunt with them again unless I slow them down. Thank you for making my point. Jacket thickness alone is not going to make a typical 40cal 200gr much better than what is currently offered. More mass is needed. A heavier bullet is the key to a slower bullet and faster bullet goals. Its easier to get the BC from the heavier bullet. It could easily be shot a little slower than a 200gr SST but fly as well or better. IMO those shooting 55-60gr loads of 4198 in break action 45s would see very little velocity loss and peak pressure increase would be very reasonable. I know that 40cal bullets in the 240gr to 260gr range shoot very well in Knight 1-20s. A 15-20% increase in sectional density over a 200gr SST makes sense to me if you want to make it hold together better. I know plenty of guys still shooting smoker 45s that would love a heavier option besides the PR bullets too, myself included. |

40 cal would make it legal here in Minnesota. This certainly has my interest. I'll take as high of BC as I can get. I will be watching with great interest. I would be smooth forming.
