Jerry Lane tested the 225 grain Pittman AccuMax .402's in sabots today. The gun has a 1 in 20" twist Krieger Barrel. The load was 60gr IMR4198, Harvester Light Blue Sabot with the Pittman AccuMax .402' 225 grain. The first group pictured was 3 shots one after another with no cooling time between shots. Group 2 is a three shot group with 15 minutes between shots. This load is safe in the test gun, may not be, nor recommended for your gun.
The distance from bench to target is 122 Yards.

I think we were on the edge load-wise possibly being too hot for current temps. Not bad for no tuning at all. There are going to be some happy saboted campers this year!

Looking good! What ignition system did the test gun have? Did you get a chronograph reading on these groups?

Looking good! What ignition system did the test gun have? Did you get a chronograph reading on these groups? The test gun was my Hankins Custom Rifle with Hankins Ignition System, H.I.S., 28 1/4" barrel. No chronograph readings were taken on these 6 shots. Jerry may have a velocity estimation.

We were shooting 3 guns and just totally failed to chrono on the other bench. Velocity is estimated at 2750 to 2800 fps. This opens up a whole new world to saboted 45 hunters/shooters...A true game changer...Kudos Kyle

Did you index the sabots?

Sabots were not indexed to the lands.

BC is estimated to be .320 G1 at sea level.

Pleased to see the results for either a .40 sabotless or in my .45s with sabots for my daughters.

I thought they would work in a sabot!
yes lots of guys will be shooting these in their .45s and .40s
I will try to send mine down range this weekend in the Apex .40.

I kinda doubt its going over 2700fps with 60gr of 4198. I think that would be faster than what ive see with a 200gr bullet. If it wasnt so dirty, Reloder7 is a good choice. Slightly slower than 4198 and 63gr does clock around 2700fps+ with a 200gr bullet. It seems really easy on sabots too.

I think many who came into smokeless MLing fairly recently may not be aware of the saboted bullet potential of many 45 cal MLers. The lighter built rifles don’t lend themselves to faster bore sized shooting and have significant recoil shooting bore sized.
Shooting saboted 40 cal bullets with BCs >0.30 in these lighter 45s just makes sense to me if the longest practical ranges and lesser recoil are desired. A 225g, 0.032 BC bullet at 2700-2750 has serious power and range potential. I’d a lot rather shoot that than a 278g Bullet at 2500’/sec with a much poorer trajectory and higher recoil.
That said, I’ve cleaned out my gun closet and shoot a robust 40 with a light one in the works. I’d rather shoot a bore sized 40 than a saboted 40 in a 45; but if I only had a light 45 (I did), I would and did shoot saboted 40s.
Sabots used within their limitations (cooling, and sometimes with wads) are very viable for hunting.

I could not agree more with sew. I have tried smooth formed, full formed etc. and they worked OK. However for the ranges I shoot under 200 yards I just seem to gravitate back to proven saboted loads for the easy loading convenience.

Steve I also agree. Smokeless is by far superior but bullet to bore performance is not needed for many. Many people switch to smokeless rarely shoot over 200 yards much less 300 and in my opinion 300 is where you start seeing the difference of bullet to bore. I think if hunters starting out would start with sabots the deer would never know the difference and it would be cheaper and easier to start with. When the shooter is wanting to shoot past 250yards then I think they should be looking at getting their sizing die and start shooting bullet to bore.

Joel, I think that a lot of the smokeless entry rifles (breakopens and retrofitted Savages) are far better suited for saboted shooting. Granted that heavier bore sized bullets with heavy loads in robust rifles provide the most everything: accuracy, knockdown power, flatter trajectory, and recoil. And “bore sized” is integral to that. But when people have much lighter breakopens, thinner barrels on Savages, etc; then staying with bore sized may not be in the user’s best interest, but it might, - depending. If 200 yards, maybe a bit further, a lighter, but higher BC’d bullet seems to just make sense to me. A 228g AccuMax going 2700-2750 is a lot more preferable to me than a 275g bore sized bullet going 200-250’/sec slower with a lot more recoil. I think many recent entries into smokeless MLing don’t really appreciate just how accurate saboted shooting can be. The first 2 bullets can be shot as fast as desired. That 3rd one, needs the wait.

What powder charge are you using to push a saboted 228 that fast?
