    Larry Gibson replied to a thread 8 x 57 in Military Rifles
    Years back I had 2K of the Rem 185 CorLoks. I worked up a load using 47.5 gr of slow burning lot of milsurp IMR 4895 which was very similar in burn rate to IMR 4320. I measured the psi (Oehler M43) using a VZ24 in new condition. The psi was...

    30calflash If your Marlin has a 20" barrel then 200 yards is realistic with the 150s using LvR powder. With the 160 FTX Hornady 250 is very doable. If you've a 24" barrel then 300 yards is certainly possible. With a 20" barrel expect...

    In the H.P. White test Keith used a 429421 cast of 16-1 alloy at 250 gr, sized .429, lubed with Lyman Banana lube loaded over 22 gr Hercules 2400. He does not state (that I could find) what the cases and primers used were but I suspect the cases...

    What was the alloy? Weight of the bullet? What was the length of the barrels from the breach face to the muzzle (the actual "effective barrel length)? What was the cylinder/barrel gap of each revolver? You merely post results (which is...

    The SAAMI MAP for the 35 Rem is based on the original ammunition time pressure curve as developed for the Remington for their recoil operated M8 semi-auto rifles. Basically higher pressure loadings in that rifle can cause malfunctions and/or damage...

    B R Shooter I understand what you're doing, no problem. Only suggestion I have is, since the owner obviously reloads, is to get 3 - 5 fire formed cases from the owner. Measuring how much those cases protrude from the barrel breach face. That...

    About how long I've been using my Redding scale. It started acting uup a while back. Gave the fulcrum aarms a good cleaning and the V recesses. Works like new now. Also the way the eyes are these days I double ccheck the setting.

    Back in the '70s I had a 4 5/8" barreled Ruger 357/9mm. I did like it and found, just as Outpost75 mentions, that with .357 sized bullets accuracy was on par with 38/357 loads. I found milsurp 9mm was moa of grouse out to 25+ yards and the bullets...

    I have never tried Elmer's load of 22 grains because the 21 grain load is very hot! kingri You might want to check that powder weight and make sure it is 21 gr. That is really not a "hot" load under a 250 gr cast.

    I recall probably the same publication. I wondered why Alliant would have changed 2400 given it's success. As I recall the writer was loading 240 gr jacketed bullets instead of cast and made his "assessment" based on the 21 gr max load for 240 gr...

    Alliant has publically stated they have not changed the formula of 2400. They still use the same formula as Hercules used. As fecmech mentions, in 2010 I did and extensive side by side velocity/pressure comparison test between Keith's load of...

    Properly mounted scout scope (1.5X Burris) works for me as does the low mounted regular scope (2.5X Weaver). The M94 Carbine also has a Lyman receiver sight on it.

    Old Coot I don't know if the results would be any different using a GC bullet with and without the GC(?). That remains to be seen. With the 30 XCB bullets from Time Killer I should be able to run at least a 10 shot test string of the GC XCBs...
