Why did Ideal make these molds? (Read 6018 times)

	I am curious as to why Ideal made several .25cal bullet molds in the 120-140gr weight. I have never seen anything in print (new or old) describing anyone using these extreme weights in a quarter bore. I wonder if it were a sales gimmick or if there was actually a use? The bullet shown in the pic is from my 25717 mold and casts a full 140gr bullet in #2. It measures 1.055” long and as cast measures .261”.Note that the three molds shown in the Ideal Handbook cut were all available in the 140gr range. What rifles could have possibly stabilized these long bullets? Not saying any were used in this rifle but the tightest twist in any of my old .25’s is the Remington Model 14 at just over 9.5”. I am anxious to hear from you guys on these bullets.

	Note that your mold is marked as to be used in the 25/35. The 25/35 has a standard twist rate of one turn in 8". Another aspect of the mold, is that it's very common in the "Perfection" (adjustable, nose pour) mold and in that mold, you can have almost any weight/length you want. So, that makes it a kind of univeral mold design. Frank

	Thank you Frank for the twist info. Any idea what twist Marlin used on the 25-36? I am familiar with the Perfection molds as I have (2) of them. The 25717 mold shown in the pic casts the full 140gr bullet(not a Perfection adjustable). I just thought it odd that Ideal would even make this. I bought it off EBay and when it came see that it has never been used and was brand new! I have yet to see any reloading books (new or old) that list anything heavier than 120gr for ANY .25caliber. Has anyone here played with 120-140gr 25's in their single shots?

	Could possibly be for black powder? From the start of offhand competition, there was a constant move toward smaller calibers. 45s went to 40s went to 38 went to..... and smokeless came along. Smokeless wouldn't have needed so many grease grooves. Black didn't really need loading manual support. Just guessing of course.

	Barnes says the 25-36 Marlin had a 9 twist.

Since the Ideal catalog lists those two as the .25-36M and .25-35, then my guess is that's what they were intended for. The 1893 Marlin lever action, and the 1894 Winchester lever action.

	Back in 1967, I ordered Lyman 285221, not realizing that it was one of those with multiple weights, where the buyer was supposed to order by weight. Lyman sent the mould for the heaviest bullet, 175 grains. I cast a few and tried one shot in my 28-30. At 50 yards, the bullet went through the target sideways. I then tried it in a 7x57 Remington #5 military roller. The flat nose and wide shoulder did not seat properly. If I got it to fit in the chamber, the base of the bullet was well below the base of the neck, extending into the powder space. This bullet would have required a pretty quick twist (9" or so). Does anyone have an idea of the original application?

	Weren't they available with an adjustable base plug that allowed the shooter to cast bullets of varying weights?

	AFAIK, not in the 1960s.

	Waterman - 7 x 57 export (Mexico, Peru etc.) Mausers had an 8.9 inch twist. The standard RN FMJ was 175 gr. When I was a kid (back before the invention of clocks) you could buy 7 x 57 hunting ammo with as 175 gr RN SP. I have a few rounds in a Peters blue box somewhere.

	285221 is a semi-wadcutter, a cylinder with a short flat point. The diameter at the wadcutter band is greater than the diameter-at-ogive points of the 175 grain jacketed round nose bullets. I still have some of those old 175 cast bullets somewhere. If I can find them, I will make up some 7x57 dummies and provide measurements.

	Those bullets look like the type designed by Guy Loverin a long time ago. they might work well in cartridges like the 25 Krag. They may be a little long for the 257 Roberts, but might work with that too.
