This is the advice Deepseek gives: This is a fantastic and somewhat rare combination—a classic lever gun chambered in a very efficient wildcat cartridge. Reloading for it requires some specific knowledge, but it's very doable. First, a crucial point of clarification: The .250-3000 Savage Ackley Improved is a wildcat cartridge. This means there is no factory ammunition available. Every round you shoot must be handloaded, starting from fired brass. The process involves "fire-forming" your brass to the improved shape. Here’s a breakdown of the process and the components you'll need, focusing on your goal of small game hunting. The Two-Step Reloading Process You can't just load a finished round right away. You must first create the brass. 1. Fire-Forming the Brass: This is the process of firing a standard .250-3000 Savage cartridge in your Ackley Improved chamber. The pressure forces the brass to expand and conform to your rifle's specific, less-tapered chamber with a sharper shoulder angle (usually 40 degrees). This is your "once-fired" brass that is now formed to your chamber. 2. Loading the Finished Cartridge: Once you have fire-formed brass, you can reload it normally. The Ackley Improved design allows for a slight increase in powder capacity (5-7%) and higher velocity, but more importantly, it greatly reduces case stretching and extends brass life. --- Step 1: Fire-Forming Loads Your goal here is not peak performance, but to safely and consistently form your brass. A common and effective method is to use a fast-burning pistol powder and a filler like cream of wheat or grits. · Brass: New or once-fired standard .250-3000 Savage brass. (PPU, Hornady, and sometimes Nosler make this). · Bullet: A cheap, light bullet is perfect. The 60-grain Nosler Varmegeddon or a similar 60-75gr varmint bullet is ideal. You could even use a cast lead bullet. · Powder: 10 to 13 grains of a fast powder like Accurate No. 5, No. 7, or Red Dot. · Filler: A small tuft of dacron pillow batting or about 1.5cc of Cream of Wheat on top of the powder to hold it against the primer. · Primer: Standard Large Rifle primer (e.g., CCI 200, Federal 210). WARNING: The filler method is well-established but must be done precisely. Do not compress the filler. The charge is very light. Always consult multiple reloading manuals for sub-load data. --- Step 2: Finished Loads for Small Game Now for your fire-formed brass. For small game (squirrels, rabbits, grouse), you want a bullet that will not destroy the meat. This means lightweight, thin-jacketed, or frangible varmint bullets. Excellent Bullet Choices (60-87 grains): · Hornady V-MAX (60gr, 75gr): Excellent for explosive expansion on small game. Minimizes meat damage and has a very flat trajectory. · Sierra BlitzKing (60gr, 70gr): Similar to the V-MAX, designed for rapid fragmentation. · Nosler Varmegeddon (55gr, 60gr): Another top-tier varmint bullet designed to disintegrate on impact. · Speer TNT Hollow Point (70gr, 87gr): A classic, affordable varmint bullet. · Barnes Varmint Grenade (62gr): Made to fragment into tiny pieces, perfect for minimizing pelt damage on rabbits. Powder Choices: You'll be using rifle powders. Good options include: · H4895: Extremely versatile and has reduced load data from Hodgdon, making it great for lighter recoil loads. · IMR 4064: A classic .250 Savage powder. · Varget: Another very versatile and temperature-stable option. · H4350 / IMR 4350: Better for heavier bullets (100gr+), but can be used for full-power 87gr loads. Primer: Standard Large Rifle Primer (CCI 200, Federal 210, Winchester WLR). --- CRITICAL SAFETY INFORMATION FOR LEVER ACTIONS This is the most important part of your question. Your rifle is a lever action. 1. Bullet Profile (Shape): Lever actions have a tubular magazine. You cannot use pointed-tip (spitzer) bullets like the V-MAX or BlitzKing in the magazine tube. The recoil can cause the pointed tip of one bullet to set off the primer of the round in front of it, causing a catastrophic chain reaction in your magazine. 2. The Solution: · Single Load: Load one round at a time directly into the chamber. This is the safest method and allows you to use any bullet you want. · Use Flat-Nose Bullets: If you want to use the magazine, you must use bullets with a flat or rounded nose (meplat) that are safe for tubular magazines. · Hornady FTX bullets are designed for this, but they are typically for larger calibers (.30-30, .45-70). You might find a .25cal 86gr FTX meant for the .25-35 Winchester, but it may not be optimal for the .250 AI's higher pressure. · Speer Hot-Cor (87gr) has a rounder nose profile that is generally considered safer than a sharp spitzer. · Cast Lead Bullets: Many cast bullet designs have a large, flat meplat that is perfectly safe for tube magazines and excellent for low-velocity, low-recoil small game hunting. Recommended Load Path for Small Game: 1. For minimal meat damage: Single load a 60gr V-MAX over a moderate load of H4895. This will be very fast, flat-shooting, and the bullet will vaporize on a squirrel. 2. For using the magazine: Load a 87gr Speer Hot-Cor or a hard-cast lead flat-nose bullet (e.g., from Missouri Bullet Co.) over a reduced load of H4895 or a similar powder. This will be effective and much safer in the tube. Final Advice: · Start Low: Always start with the minimum listed powder charge and work up, watching for pressure signs. · Get a Manual: The Lyman reloading manual is excellent as it contains data for a wide variety of cartridges, including the .250 Savage, which you can use as a starting point for your Ackley Improved (starting 2-3% below max .250 Savage data is a common approach for fire-forming). · Consult a Smith: If you are new to reloading, especially for a wildcat, consider having a knowledgeable gunsmith or experienced reloader guide you through the fire-forming process.
