Ask the Factory!........those weights are the weight of the powder in the rounds originally, the average for the 20 rounds was 49.45grs so I have reloaded them all at 49.4grs using the original powder.

Alpha.....how do you propose removing live Berdan primers?......and yes they are Berdan.

As Saddler said I would rather clean my barrel properly than p#ss about with live primers!.

That doesn't make sense......if they were Boxer primers you could remove fired ones, replace them and reload the cases......it's Berdan primers you are stuck with (although there are ways and means......)

No mate, I've run out of N140 at the moment and was bored so I thought I'd see if I can improve on the milsurp ammo I've got........I reloaded around 220 Berdan-primed Egyptian brass milsurp cases with Egyptian 180gr lead-core BT bullets and 42.5gr of N140 last week as I was bored, I had tried that load the weekend before and they were pretty accurate so I knocked a batch up.Still got around 150 of the cases left, plus some Russian and Polish cases,and a load of 180gr and 150gr bullets left so need to get some more N140 sharpish.

i've not touched my n140 in a long time, other straightwall cals have taken over the need for loading. I bought new lead bullets from rog for my 303 but i haven't loaded a single one yet, i keep thinking i'd be better loading them slower anyway as i've mainly shot 303 at 100 yrds... the full load of n140 seems wasteful and not to mention shoots a fair distance off the sights...
one day i'll get over to severnside and shoot at the range it was meant to.

I shoot at Sennybridge with Offas Dyke, it's good to stretch the range out some as it can get a bit samey shooting at 100m at my local club range.

Well.....I tried out the "improved milsurp" today and I have to say I'm impressed, got consistent 1.25" five shot groups at 100m and a couple that were a smidge over an inch so quite an improvement and pretty much as good as 7n1 54r sniper ammunition.I reckon that could be improved on even more with a good quality 150gr bullet so the hunt is on!.

Anyone know of a producer of .311" 150gr BT FMJ bullets other than PPU?.

We's been motivated 'as us !

Just pulled 120 rounds of 7.62x54R milsurp with the plan of disposing of the original steel cases and reloading the bullets and powder into some nice new brass cases. The bullets were 150 grains with hardly any deviation at all to them in the random selection of 30 that we weighed. We weighed 30 powder charges too, again at random, and found they were between 48.7 and 49.1 grains. We plan to reload all the rounds to the modal value, 49.0 grains.

We did notice that, occasionally, one of the cartridges would take a little more effort to pull than most others, perhaps a tighter crimp? That occurred with roughly one in 10 cartridges.
