    Hi, guys I have been flitting between ideas for this one and I mean a whole myriad of different thoughts! Like anything from 218 bee, 220 swift, 257 Roberts, 277 Weatherby Magnum, 7x57R, 300 Win Mag, 33 Winchester, 358 Norm Mag, 375 H&H, 405...

    "The next shot sounded slightly, very slightly, different. But nothing for me to suspect a squib load, it had a report almost as loud as a normal shot." If the OP's loads were correct it sounds to me like the 2nd shot was a "squib load" and the...

    The original 7.65 Argentine was loaded with a 211 gr RNFMJ at a nominal velocity of 2130 fps out of the long rifles. That was changed to a 185 gr FMJ BT at a nominal velocity of 2467 fps out of the longer barrels. I believe the rear sight...

    You might use the data in Lyman CBH #4 for the 265 gr cast as a guide.

    Back in the late '60s and '70s I had probably a dozen of them (both Colt and S&Ws) go through my hands. Also a couple M25s. I still have one S&W M1917 that had been altered with a M1911 rear sight dovetailed into the top strap and a higher blade...

    Major problem I had with a couple 30 cal Lee GBs that were supposed to be duplicates of Lyman designs is the designer apparently spec'd them for he WW + Pb at 50/50 apparently based on the WWs he had stored behind his shed which he said we couldn't...

    Larry Gibson replied to a thread Leading problem in Cast Boolits
    There is no disagreement. What I said was "fit is not always "king".......". I also said; "My testing has revealed that a bullet over .003 of groove diameter will give less accuracy and probably some leading if the lube isn't correct." Thus...

    Many shoot "off the book loads" that are safe for the firearm used in. How many here develop loads for milsurp powders that are not "book loads"? How many here develop safe loads for wildcat cartridges that have no "book loads"? Again, there is a...

    andym79 started a thread M17 in 303? in Military Rifles
    Hi guys, I know that the M17 was based off the P14, but it was the US Enfield in 30-06 rather than 303! If a rifle is an M17 in 303, is it likely its a M17 with a P14 bolt?

    Wasn't your bad, was mine. H&R didn't make break open revolvers in 32 H&R......I was thinking of the wrong models (the 38 S&W and the 32 S&WL's in the H&R 900 series revolvers) and said so in response to MT Gianni's post. However, as both MT...

    The 358156 is my favorite top end performer in the 38 SPL and the 357 Magnum. It also is a solid performer in my M91 Argie 35 Remington. I was under the impression the 358156 was designed for 38/44 level loads with 2400 with the bullet seated...

    Larry Gibson replied to a thread Leading problem in Cast Boolits
    I'm going to be a heretic here and state; fit is not always "king"....... Before I read about the bullets just had to fit the throats of a revolver or you'll get leading and bad accuracy in gun rags and on forums I shot thousands of of commercial...

    Larry Gibson replied to a thread Leading problem in Cast Boolits
    What "Lyman lube"? What % of tin is added via "a touch of solder"? Does the "leading" clean out with normal cleaning or do you have to use other than patches and a bronze brush? I shoot that same bullet cast of COWW + 2% tin, sized .430 and...

    "Quite early in the game I learned the true advantage of using bullets with gas checks on them. Further, bion, I found the ubiquitous 358156GC to have been one of my best performers." That is exactly my own experience with the 357 out of several...

    Hi guys, I was thinking about doing a martini in 40-70 sharps straight, has anyone done this or something similar? My concern is about the length, will it make it around the turn, the case is 2.5" long. Its basically a 408 calibre version of...

    I believe you are correct. I was thinking of the H&R 900 series top breaks. My bad. Yes the H&Rs were/are much weaker than the Rugers. I first read of loading up the 32 H&R in an article by Ross Seifried (SP?) in G&A magazine years ago. Then...
