i have some 7.62x54r russian 148 grain bullets. has anyone ever used the pulled bullets in their enfield? i have a savage no4 mk1* i am going to start reloading for. i'm going to get some partizan ammo, fire form it, then reload with those cases. these are .311 148 grain bi-metal jacketed boat tail bullets.
has anyone tried this before? i'm hoping to get some good groups with this ammo. my bore is very good on this gun. eventually i also want to cast bullets for this gun (more economical) i am new to this forum, and i hope you welcome having me thanks |

Yes I have reused pulled bullets as long as they are not deformed or damaged

Just be aware some older, more worn 2-groove barrels don't like BT bullets.
Its a bit of a crap shoot till you know your individual bore.

The bullets I am using are boat tail but not overly so.
This one was fired in my 'rust textured' bore rifle. The rust has not actually altered the profile of the throat and this rifle shoots them pretty accurately. These are 180gr PRVI Partisan bullets. They have a fairly blunt nose, almost semi-spitzer which probably helps. They are .310 diameter so I was surprised they shot so well but when I found the bullet jacket I realised how large the support area on the bullet was. The bullet did not fill the groove which is closer to .318. I have some 308 boat tail's I'm going to try in it one day. Those are long and pointy with a long tail. I don't hold out much hope for them. But 148gr boat tails may have way too short a bearing surface and too much jump into the leade for bullet alignment. Only one way to find out.

I your groove diameter is running that large I would avoid using them as the gas seal will be poor and bore wear may be accelerated. The most accurate bullets (generally) are the 174-180 flat bases in my 303s.

Who makes the flat base bullets? I am using Sierra Match kings which are boat tailed, they do work well in my rifle, but I would like to experiment with some flat base ones in the 174 or 180 range.

I wish I could find some. I ended up going to 150 Gr ones just to get the flat base.

The Sierra 180 Grain Pro Hunter is Flat Based as is the Speer 180 Grain and the Hornady 174 Grain, Being in Europe you may be able to get the Sellier and Belloit 180 FMJ which is (was) flat based last time I checked. |

This bullet recovered by 303guy, is a perfect example of debunking that BT v FB myth.
Note the areas marked, from the left, maximum bump, on either type of projectile, occurs here, if a flat base, then the rear obturates and gives the effects of arrows centre and right.
If a boatail, it creates a pressure bump at the rear contact point, centre arrow and a sealing ridge as shown in right arrow. All current problems with inaccuracy these days are directly attributed to poor ammunition selection, poor reloading practice.ie: not duplicating the original spec's, or sloppy or worn out barrels. |

When I was able to recover most of a jacketed bullet, I also found evidence of swelling at the rearmost part of where the jacket is in contact with the barrel. Long range accuracy can be a different isse.

I get excellent accuracy using the 147-148 gr steel core boat tail bullets in my Savage two groove barrel. These are the only boat tail bullets that will work with my Savage.
As .303 guy says the broad lands of the two groove bore compress the body of the bullet extruding the jacket and core deeper into the grooves. The steel core soviet bullet has a sheath of lead between jacket and core. The core acts as a mandrel so the lead pushes against the jacket forcing it deeper into the narrow grooves. You can tell if your bullets have the steel core by examining the exposed base of the core in the open base of the jacket. A steel needle will not scratch the base of the steel core. You will likely see a small amount of lead around the base of the core, this is part of the lead sheath mashed out during the manufacturing process. I scrape away the flash while I'm at it. My 147 gr bullets all from the same lot of ammo miked at .3125, which may not be common for these. Soviet 7.62 bullets were designed for use in worn or over sized bores, and are an excellent choice for the Enfields. The crimping cannelure of the 147 gr bullet is too far back from the nose to allow seating to the groove while maintaining the proper OAL of the .303 cartridge. I seat mine to a OAL of 3" , with cannelure below the case mouth, and this works fine. I don't crimp my handloads anyway, instead using a tight neck sizer and a homemade expander that leaves the neck very tight. Flat base bullets are usually the best choice for the .303, but the Soviet bullet is an exception. Inaccuracy with boat tail bullets is most often due to oversized bore and blowby caused by eroded throats. The MkVII ammunition used a card between bullet base and charge which served to provide a momentary seal as the bullet bumped up and passed through the throat. This all but eliminated blowby. Over the charge cards are not feasible when boat tail bullets are used.

To answer the question that was originally asked:
I've used the pulled bullets from 7.62x54R ammo with good accuracy. They mike out at about 0.312 and seem to work fine in my 0.314 groove dia. barrel. Extensive tests have proven that the copper-clad soft steel does not wear barrels any more than regular jacketed bullets. The Swiss use copper-clad soft steel for their military ammo. In many cases they give lower pressures than a regular jacketed bullet of the same weight, all other things (powder charge, cases, primers etc.) being the same. I won't hesitate to use them in barrels with a groove diameter over 0.310. |
