The Barnes is very close to the 200 sst in tested BC. Very little difference in drop, even though the sst looks alot sleeker. Hornady lists the sst's BC higher than results show.

the bx is a great bullet, I wish they would put a tip on it to improve the bc a little. as far as a deer killer in the saboted .45 they are probably on top of the heap, I wouldnt be afraid to shoot elk of bear with one for that matter as long as it had speed behind it...Bill

Savage Shooter Yes the bottom radius of bullets is creating an issue for accuracy. This has cropped up more than once in both calibers. If it isn’t punching the sabot it probably is really deforming the base-cup of the sabot causing erratic groups. The higher and sharper the pressure the more pronounced the affect appears to be. Eventually I will be returning and exploring this condition with the 50 in trying to get a combination to work with the 200SST 40Cal. I believe Edge has the right idea of using a washer under the bullet to distribute the force of the bullet with the pronounced radius to the sabot’s outer perimeter inside the petal area. In the future I will be returning to play with the duel sabot and 40Cal bullet with observing what the washers will do.  As they say nothing ventured nothing gained. Don’t know if there is any useful info for you here but it may trigger another line of thought to work with. Ed |

Ed Funny you mentioned the washers, I looked to see if I had any aluminum washers that were .40 outside to try but only have some that will fit the .50......when I revisit the the .45 washers are on the list to try. I think the washer would give the support the bullet base needs to straighten out some. It sure helped the boat tail designs in the .50's. |

Yes, they have now changed ALL production to the flatter base on the 195bx. Due to oooutstanding feedback from shooters. Thanks to Barnes from us all...... Now if someone with any stroke with Hornady could make them understand what the difference means to shooters. As Barnes has recognized this change makes the bullet work just as good as before for the black powder guys but helps us smokeless crowd huge!! Now about a 225-235 Parker BE in a .400"......anybody got any pull with Parker?? I know some of us here are striving for the seemingly elusive .5 moa gun and IMO we will first need a .5 moa bullet!!!! ;D Here is the email I received from Ty just last week:::: Hi Mark,
We have redesigned the existing 195gr 45 cal MZ bullet to have less radius where the shank meets the base. This has increased the bearing surface of the base of the bullet and seems to help those that drive it to extreme pressures. From this point on we’ll only make the new version. You can tell it’s the newer design if the lot number is 4272 or greater. The part number 40016 (15pkg) & 40052 (24pkg) will not change. Please feel free to call me if you have any questions.
Thanks, Ty

Great news on the bullets. I think it has been brought up with Parker on a high BC bullet in .40. I think his answer then was no. If we could get something that comes somewhere near the 325 .45 Parker in BC we could shoot sabotless in a .40 or saboted in a .45 it would be a big step forward for us. The 325 shot to a decent speed would have a little more recoil than I care for, but I'm getting old and soft. I thought about if the DMB barrels shoot good, I might get a 1in18 8groove made fairly long (27or 28") and put a removable muzzle brake on it to tame a 325 Parker.

Mark...........here is something you might try with the SST's..............I took the .45 cal. .060" thick veggie wads and cut them to fit inside the blue Harvester sabots.....under the SST. I used a 7.62 x 39 case which I cut down until it matched the inside of the sabot. (probably a .40 S&W case would do the same thing) I then used it as a "cookie cutter" to resize the veggie wads. This gave some pretty good support to the base of the bullet all the way out to the inside of the sabot. Just like a washer would? My results did not show any difference........but then again, I was not having any problems other than a very occasional blown sabot when I was pushing above 3,000 fps. Your results might be different.
I have already turned the bases on six SST's for Tuesdays range session. My plan is to shoot a five shot group with the standard and five with the flattened bases using 62 gr. of H-4198. Flattening the bases causes a loss of 1.5 gr.

Richard Good maybe this will give an idea if it is just "my gun" won't shoot them at the higher speeds. I can keep them pretty much moa and a bit less at 59 and 60 gr H4198, but they will not hang in when I go up and it is just not enough pressure difference to cause this dramatic of change. I sure don't mind "having" to shoot the Barnes, just would like to learn "why"........ |
