Many, if not virtually all of us, want as flat of a trajectory as possible, least recoil necessary, and adequate terminal performance which includes enough energy to get the job done efficiently. 45 cal guns let us shoot both 0.450-0.452 bullets sabotless if they are resized and 40 cal bullets saboted. 40s allow us to shoot 0.400" bullets w/o resizing and just knurling. A problem that exists, IMO, is the lack of hi BC'd bullets in the 0.400" size. I get appx 0.265 BC by my drops with the 200SST, close to 0.235-0.245 with 195B(DaveDaub gets less and his calculations may be more accurate than mine: I think I have higher velocities), and a lot less with the other 40 cal bullets.
I e-mailed Bob Parker requesting his consideration of a 225-275g 0.400" BE. It could be used sabot less in 40 cals, saboted In 45 cal smoky and smokeless, and by far in the largest market of all - smokey 50 cals. For twist purposes of most 45s and 50s, the 250g or even 235g bullets might be optimum.
Parker could lay claim to having the highest BC'd, jacketed MLer bullets commercially available.
Thoughts?

I too have sent Bob Parker a messege reguarding the interest in a 225gr or 250gr .400 bullet for us all. maybe if we all bombard him with some messeges he'll throw some at us soon enough? my reasoning with wanting a longer bullet isn't so much flatter trajectory, although I wouldn't complain, but is more of having a higher sectional density. I think this would help with not just holding energy at longer ranges but also help to get those of us who are into speed in getting a pass through at the shorter ranges.. just some of my thoughts  |

If it could be made to shoot ACCURATELY, I can imagine a
Lehigh type bullet (perhaps not even the same material), with a
plastic pointed tip that could have a BC better than .3. Anyone
who has seen them know why they are long for the weight they
have--that HP is a CRATER! Cover it up and who knows? An ogive
change might also give such a bullet a better BC.
P.S. If they kept the diameter more consistent and placed the
knurled rings further apart, that just might take care of the
accuracy problem.

Hawks already offers a 235gr and a 225gr but they are hollow points, Im fairly sure they also have some heavy flat points too. Ive shot the 225gr and it is a thumper even with BH209.
Ive been talking to them lately about a .400 220-240gr semi spitzer like a Barnes O. I should know more about it in December. I need a 3 box minimum at $44 a box to get them.
Any preference on jacket thickness?...they offer .025 and .035.

Well I remember the Hawks didn't work very well in the .50 cals saboted,,, not enough bearing surface wasn't it

The 225gr is the 2nd from the left, next to the hard cast.  MeisterCast260grRNFP/Hawks225grHP/Xtreme 220/200gr plated/Lehigh200gr/SST200gr/Harvester200grHP/Lehigh185gr/MontanaGold180grHP/Hornady180grXTP/Barnes175grMZ/MontanaGold165grHP The bearing surface is about the same as a 200 SST but that is why its taking awhile. Trying to figure out which weight and ogive shape that gives a good sized bearing surface. |

i talked to Bob personally about the same subject and from the way he talked to me i seriously doubt it will happen BUT i hope it will as i would also like to see it

Sounds like a great idea SW, let us know about Bob's response and how we should approach (pressure) him!

As I recall the 250 grain Hawks bullets had two problems.
Short bearing length and also a large base radius.
edge.

It's a great idea, I went so far as to price swaging equipment to solve the same problem a couple years ago. I thought someone talked to Bob about this very subject a few weeks back and it was said it would be $2 or more a bullet if done?? If it were a dollar a bullet I would shoot a lot of them.
The major limitation may become twist. If it won't stabliize in 1:28 you lose the BP market.

As I recall the 250 grain Hawks bullets had two problems. Short bearing length and also a large base radius. edge. He did have a few heavier spitzers left when i got my 225gr HP but i didnt try them and now they are out of them. They do have several round tip and round nose bullets in the .406+ range that can be resized in a minute with a $17 Lee resizing die if you have a press. The ogive is likely too long though vs the bearing surface. Resizing them might help a tiny bit. The bearing surface seems to need to be over half the total length or longer depending on the ogive shape. 2/3 the length is probably best but that will likely eat into the BC quite a bit at smokeless speeds. I resizied those 260gr hard cast but IMO they shot just as well at .406 at BH209 speeds. |

I still have a few boxes of the .458 and .452 I think
