Furthermore, I’ve never experienced (nor heard of) any failures from a reduced 30-30 load; worst case would be a few annoying flyers (which I feel I have personally experienced with reduced loads of 2207 and 2206H).
more volume for weight) than your traditional smokeless powders, meaning the cases are a lot fuller for the equivalent charge. You will be redirected once the validation is complete. Trail Boss granules are physically less dense (i.e. The fact that it was a lever gun was also intriguing to me.
Lever guns were something I had little experience with, so the whole lever action concept was a field that I was yet to explore. What is the rising action of faith love and dr lazaro? Here is another interesting read about simply using tissue paper as a filler. In fact I was having to increase the crimp pressure so much, it was at times denting / buckling the shoulder of the shell when seating. Copyright © 2020 Multiply Media, LLC.
EDIT: Another amazing 1 moa group using a 150gn FP semi-jacketed over 35gns of H335 (similar to AR2206H), again shot by a moderator from http://www.marlinowners.com: Berry’s copper-plated 150gr 30/30 bullets are extremely accurate over 21gns of AR2207 (aka H4198), yielding approximately 1850fps. Without it, projectiles in the magazine can seat deeper and deeper after each shot, equating to a progressively smaller ignition cavity that can ultimately result in a catastrophic detonation. The powder will always (to a lesser or greater degree) be in contact with the primer.
It’s not the most suitable powder for jacketed (a bit fast-burning for full-power 30/30 loads), nonetheless yielded good accuracy at around 2100fps. Generally speaking, the faster you push a lead projectile, the more leading you’ll get. This helped me realize that constant 2moa for target work.

At this stage I cannot conclusively comment on the significance of a slightly larger projectile in a Microgroove barrel, you would really need to slug your barrel before running over-sized projectiles, something I am still yet to do.
A real no-brainer, but not necessarily any more accurate than your traditional FN projectiles. non-circular holes. ADI’s/IMR’s new Trail Boss powder is also an option for lead. This large sample size group was achieved by pan lubing the coated projectiles. This was shot through a clean, cold barrel. Ok so back on to lead; gas-check-less (checkless) cast-lead is perfect for varminting and plinking (at close ranges), but is really not appropriate for classic, medium to large 30-30 game (like deer).
This process is automatic. The coating restricts the amount of lead that rubs off as the round moves down the barrel. I’ve also read about stories of catastrophic failure due to an unusual pressure wave forming from a very light load in a large case (like a 45/70). Just make sure you are usin Apparently 30.0gns of Bench Mark 2 (aka IMR3031) and 35gns of H335 work pretty well with the 150gn projectiles too; although please double check your manuals first for these two powders, as I’ve never personally used them. Same load as above, but no lubing (just the standard coating on the commercial projectile). I sanded my forend back a little and then re-coated with some tung oil so the forend band fits slightly looser now. Your marlin model 336 was produced in 1976.

Ano ang Imahinasyong guhit na naghahati sa daigdig sa magkaibang araw? Another bonus is that reduced loads prevent beginner-shooters from developing any kind of flinch from the normally heavy-recoiling .30 cal carbine.
Handling a cartridge in different ways prior to loading can in fact lead to different muzzle velocities (and therefore, theoretically, different POI’s). And I totally agree about your sights; it’s definitively best to develop your loads with a scope if that’s an option. Reloading the Marlin 336 in .30-30 Winchester; Coated Cast Lead vs Jacketed. People suggest chamfering the mouth further, but this will only reduce the lifespan of the brass. As it turns out, Marlin…
To reiterate, if you push any kind of checkless lead too hard, and gas will “cut” around the sides of the projectile upon pressurization.
Nevertheless the fancier 160gn Hornady FTX “Leverevolution” are probably best paired with HODGDON LEVEREVOLUTION POWDER.
This stunning 1moa group of a cast-leads was shot by a moderator on http://www.marlinowners.com: Generally speaking, for semi-jacketed hunting projectiles, the modern 30-30 demands a medium-burning powder. I’ve got a 336TS with 18.5inch barrel. We’re talking in the realms of 1/5th (or less) of the price of commercial semi-jacketed projectiles, and even cheaper if you cast yourself. ( Log Out / DISCLAIMER: This load data should be roughly translatable across equivalent (non-ADI) powders, however as stated on ADI’s website, there could be up to 5% variance, so be careful. When did organ music become associated with baseball? Fill in your details below or click an icon to log in: You are commenting using your WordPress.com account. What are the problems loading a Marlin 336? Five beveled “checkless” lead projectiles next to two gas-checked lead projectiles ( right ). The 30-30 (metric 7.62x51mmR) was the US’s first small-bore cartridge designed for smokeless powder. Thinking of using 2206h with the 170gr Sierra Flat point bullets. I have fired 100’S of rounds in my 30/30 using the HRBC 165 gn cast bullet and 16 gns of adi2207. For Australian customers, there are a few projectile manufacturers who sell beveled, checkless, “polymer-coated” .310″ 165gn RNFP 30-30 hard-cast lead projectiles.
The new 160gn Hornady FTX “Leverevolution” projectiles over 32.0gns of AR2208 (similar to H335) would be a solid start. When seating the lead projectiles, I noticed some of the lead was being shaved-off due to the tight mouth fit. In our case however, without gas-checks, brinell hardness is still not really a huge factor. Courtesy of Wikipedia, a .30-30 cartridge (center) between 5.56×45mm NATO (left), and 7.62×51mm NATO (right). Save them for varminting or the range. So you might ask, why would you even consider factory semi-jacketed? This 5 shot group was in fact achieved with a peep sight; get rid of those factory dovetail sights and heavy factory trigger ASAP. Change ), You are commenting using your Twitter account. My 12 yo son likes this load, as it has little recoil. It’s age means there is a lot of handloading data available. These days I run a williams FP-336-TK receiver with a Lyman 17AHB front peep, this gets me to 300m with a 1500fps cast-lead projectile with acceptable consistency. They have a gummy spire-point and thus a higher ballistic coefficient than your traditional FN projectile, meaning a flatter trajectory and a bit more stopping power over those medium distances (200yd+).
Very little, as far as I can tell. If you’re unsure, do more homework first and verify your new load from another source before reloading. Fast hunting loads heat a light sporter barrel very quickly, meaning stringing long groups of shots together will result in poor accuracy. Focus is placed on shooter ergonomics rather than long range performance. Both of these projectiles are more than adequate for true medium game. The idea of polymer coating is to provide integrated lubrication to protect from leading. Trail Boss in contrast fills considerably more volume relative to its weight; 9gns fully fills the case yet outputs a mellow muzzle velocity of ~1200fps!
AR2206H yields around 2.5moa with ~18.5gns of (over a 165gn RNFP lead projectile). One thing I learnt not so long ago was the tightness of the barrel bands and screws can affect accuracy, particularly when the rifle starts to warm up. I was able to achieve a consistent 2.0moa with a reduced load of ~16.0gns of AR2207. Here is a really interesting article relating to this issue, and part of the reason I prefer to use ADI’s Trail Boss powder over these traditional powders (for reduced loads). Basically, they are simpler and easier to use. DISCLAIMER: Especially for your full power loads, ALWAYS ensure a proper crimp. Down here in Australia, most use (and supply) ADI powders. I noticed a lot of people throwing around the idea of “hard-cast” lead projectiles. In saying that, I think any kind of failure would be highly unlikely in a 30/30 (with these two particular reduced loads/powders), as they both fill more than 50% of the cavity. As it turns out, Marlin produce some of the best value “no frills” lever-action hunting rifles on the market and the 336 ended up being a great entry into the world of lever guns.
