I'm still pretty new to smokeless. I looked in the data but couldnt find this particular load. I am currently shooting 60gr IMR 4198 with good accuracy. Since the season is wrapping up I am planning on trying different loads.
My current setup is the APEX 45/70... I have knurled up some 200gr SST's and some 195 Barnes to go with the Smoothe Blue Sabot. Previously my gun didnt like the barnes so I stuck with the SST's.
Would 50gr 4198 and 10gr 5744 (I would be using 5744 because I have a bottle on hand from my previous Savage) be a good starting point? What are the particular benefits with a duplex load using sabots? I have contemplated trying sabotless, just not on the immediate radar.
Thanks for the info!

I have not used 5744 for a starter but I have used 10 grains of 4759 and 50 grains of 4198 with those bullet weights in a 45 with good results.

tenn.guy: Not long ago, I traced that load in a 45 cal barrel, 5744/h4198 10/50gr 195bx (63h,load archive). FWIW, it may not be as temp insensitive as 4759/h4198 10/50gr, 195bx. In my barrel, I begin to see sabot failure when peak pressures get much above 32kpsi.So, if my numbers are meaningful, at temps exceeding 60 deg F this may be a problem for this load, tho YMMV.

TG Thanks for the info. It does make sense... Do you have a link to load archive, I couldnt find it? Also I would assume, I wouldnt want to increase the booster over 10 but it would be acceptable (safe) to lower load to 8/52 ? Any idea of potential FPS with your findings? I appreciate all the advice. |

I had to drop booster back to 7 grains to keep sabots from intermittently blowing in 65 degree temps. Didn't test any warmer than that due to finding SR4759 to be a better booster due to grain size, IMO.
When testing with 5744 I found Slufoots load to shoot real well with 4198. I was shooting it at 7/53. It would need to be wrung out over time to test reliability, but the couple times I shot it was very accurate.

With very little time for getting ready to use the HandiRifle(20" barrel), I used Slufoot's load of 7/53 5744/H-4198 with both 200 SST and 195 Barnes, with a wool wad and LBH. This was extremely accurate. Great starter load. I didn't chronograph it. Bet 2630'/sec.
I'll try 4759 and VV-110 to see how they do. Note: the 20" barrel of the H&R likely is optimized at a slightly(faster burning) load than a 22,25,etc. Example with the 20 and 22" H&Rs if the 20 does well with 7/53, possibly the 22 might do better with 6/55 and the 32 might do better with 7/65 4759/Varget or 3031or H-4895. Don't know Apex length(20"?).

It will be interesting to see how the 7/53gr load does for you over temperature swings. FWIW, and as noted above, in my barrel, there was significant temperature effect on both pressure and velocity for the 7/53 load, though the numbers I have are limited. And, as always I may be wrong about this and YMMV. Good luck.  TG |

And, as always I may be wrong about this and YMMV. Good luck. TG Yeah I would buy that! I noticed when it was in the 60-70 degree range it made about all the pressure a Harvester Sabot could take. When picking up sabots I notice quite a bit of stress... Didn't realize velocity fall off was that bad when cold. With this load combo I would bump up booster a grain to like 8/52 if temps were cold. POI will remain pretty consistent to warm weather sightin with 7/53 in doing this. Just any opinion as I have NOT tested this. |
