Hi John Boy. 

Just curious what rifle/barrel/twist you're using with the resurrected Lyman bullet? Also what is the difference in the two cherries used ? 

                                      Joe.

John Boy,
The 375166 looks quite close to the 37579 that I have in the 325 grain weight. I was wondering if you may have been able to shoot both styles to make a comparison.

Joe, they look like 2 different bullets to me.  Ogive radius's are similar though.  No, I have never shot this bullet.  A current production 38-55 that I have had good results with is the Lyman 378674
#2 - On all my BPCRs - iron sights, LR verniers, except mid range ones on my gallery rifles.  I shoot 1000yds about 4 times a year and so far, the verniers haven't let me down - neither have my eyes  
#3 - I hear you about the 10 shot groups.  At this point, if it will shoot 3 then for 10 it should shoot the same barring no bad let offs or other goofy things that do happen.  You know what I'm saying.  Since this is a bullet that has never been flown in over 40 years, I wanted to see quickly if it would or never will be.  Today, I took another batch to the range with recipes different than the 1st batch.  I'm an x'perimenter and also am a devote fan of felt wads.  Today's batch had 3 variable changes and yes, I know it should only be one at a time.  Anyway, construction paper OPHW instead of Red Rosin paper - variable powder charges (42-44-45 and 48grs of Swiss 1.5) and 0.10 dry felt wads.  I also shot up the remaining 42gr Goex CTG from the 1st batch ... which is a coin toss with this bullet!  I'll post up the groups after I get them measured.  The groups today are holding in there to say, that the bullet is A-OK in my book.  And when I find the right recipe combination ... no looking back.  Then, I will shoot 10 shot groups based on the best recipe(s) group averages.

John Boy,
Here's the 37579 version I was wondering if you had tried out. OAL in this 325 grainer runs at 1.175 inches.

My older copy of the Lyman Cast Bullet Handbook shows that the 37579 was available in seven weights from 135 gr. up to 325, the only differences being the number of grease grooves, based on how deep the cherry was positioned in the mold blocks.  That was a very common practice for many of their older bullet designs.

John Boy, you probably have already come to this conclusion, but just in case somebody is coming late to the Ideal/Lyman show, there were certain of the Ideal designs in a series called the "Perfection" moulds.  they were all nose pour with a movable base plug to lengthen or shorten the bullet by a specified amount (based on the number of grease grooves.)  Some of these designs survived as single weight, base pour moulds as well.  This is possibly what we are seeing here, especially in view of the low number.  BTW, if somebody would reintroduce those old Perfection moulds, I bet they would be brisk sellers!!  I've got an old .25 and .32, but would love to own one in .38 and another in .45.

1:18 is mentioned.   Anyone shooting this in a 1:15 twist?   

I was considering a Hoch nose pour but have several Accurate molds I like quite a bit.
