The twist is 1-38 , but I think that's more from the backer boards on our range that are getting a touch shot up again . I've run a good number of 375 grain bullets through this barrel and several others with the 1-38 twist with very good results .

This ones making me contemplate taking it up to 47.5 and 48 grains . A load that shoots inside 2" at 100 yards and clocks 2000 FPS + at the muzzle wouldn't be shaby at all especially when one considers the velocity is from a 19" pipe !

Is that at 100 yards? If so that's plenty good hunting accuracy. 8-)

Maybe the stability is getting better as velocity goes up?

That's at 50 when I was clocking loads Wednesday . Me shooting at 100 with a 4x scope isn't always so great on paper . This little short rifle usually is hunted in places where a 75 yard shot is long . I plan on using a different target this week and shooting some 100 yard groups . Wanna try 46 and 47 grains at 100 yards and then perhaps try 47.5 and 48 at 50 yards over the Chrony .

Loaded some more of the MM/RD 432-365GC for in the morning H322 46 , 47 and 48 grains . I could not get 49 grains in the case and seat the bullet deep enough .

Also put some targets in the truck with a larger black bull for use with the 4x scope at 100 yards .

I think I'm gonna go with my original game plan in this rifle . During the Damage Control Season in this rifle I'll use the Lyman 429650 first and once I get a deer with that one I'll go to the RCBS 44-300SWC and once I kill with that one then the Saeco #433 and finally if I kill with the three of them the LBT 431-300GC . All are loaded with 50 grains of H322 except the LBT bullet which has 49 grains .

And once the DCP season is done I'll switch this rifle over to this MM/RD 432-365GC bullet in the little rifle for the regular gun season here in Virginia !

Just returned from the range !

I have my circa 1967 rifle sighted in at 50 and 100 yards with the RCBS 44-240SWC , Lyman 429244 , Saeco #431 and the LBT 430-250GC . Also have the sight settings determined for the LBT 431-280GC in that rifle as well .

Got the sight in on the Retro 444P with the Lyman 429650 , the RCBS 44-300SWC , Saeco #433 and the LBT 431-300GC .
I also took velocity readings on the four 300 grainers and got the average of three shots as follows .

Lyman 429650 with 50 grains H322 2005 FPS
RCBS 44-300SWC with 50 grains H322 2026 FPS
Saeco #433 with 50 grains H322 1945 FPS
LBT 431-300GC with 49 grains H322 1956 FPS

Not bad velocities for a 19" barrel I think .

I also did some more work with the MM/RD 432-365GC with H322 . And I am now getting decent groups at 100 yards but I believe with more magnification then 4x I could do better as the groups were averaging between 2 and 3 inches . I also took velocity readings for the charges and they are the averages of three shots .

46 grains H322 1908 FPS
47 grains H322 1946 FPS
48 grains H322 1984 FPS

I wanted to go to 49 grains as well but I couldn't get it in the case and seat the bullet correctly !

Perhaps later this week I'll hit the range again and do a little more with the MM/RD 432-365GC and perhaps my circa 2001 Marlin 444 and some of the 400 grain plus bullets .

Thanks for the data. Those are some thumping loads. :)

I was hoping for 2000 FPS but I didn't get it and as I said I couldn't get 49 grains of powder in the case and seat the bullet deep enough .

To be honest the other 46 and 47 grain loads shot better at 100 then the 48 grain load . But for what I'm gonna do there is no great accuracy difference . Also for what I plan on doing with the bullet 100 FPS give or take isn't gonna matter either .
