.22-250 36 Grain Varmint Grenades

Hi All,

 

I have a friend who is struggling to get these to work accurately in his .22-250 with BLC-2.

 

Even in the .223 they have a reputation of being a bit rubbish. I managed to get over this by going a bit off piste with the load data and actually run mine at Barne's data for COAL but with a load of N120 calculated on quickload and then verified on the range and indeed with excellent accuracy.

 

I'm wondering if similar success could be gleaned in the .22-250 by using a faster powder than usual, such as N120?

 

 

Cheers

Isn't 36 grain a bit light for 22-250?

I thought that calibre worked best in the 45-55 grain region

55g blitzkings work brilliantly for me- generally hole on hole accuracy with minimal (actually none) load development.

The very frangible and very light class of bullets show spectacular MVs in varmint rifles-some can show good accuracy-I've .3 at 100y in a 222,and emphatic terminals on small vermin while velocity remains high....

But the laws of physics won't be denied,and there is a considerable haemorrhaging of velocity from such very low BC bullets,so that any initial slight ballistic advantage is reversed within normal shooting ranges,compared to better BC varmint bullets for all round performance.

Hi All,

 

Yes not the most ballistically efficient bullet, but we have a local source here at around £12 per hundred. :D

 

The VGs are strange because they are very long for their weight so behave like a much heavier bullet, in terms of required twist rate, rpm to stabilise.

 

Anecdotally, I had heard a lot of bad news about their accuracy in the .223 but luckily a chap had success with N120 and that followed in my rifle.

 

I'm wondering if the harder sintered tin construction of these bullets needs a bit more of a sharper thump to get it to obturate into the barrels rifling.

 

 

Cheers

They will be comparably long for weight-tin is lighter than lead.

Poor performance on large varmints at 250 yaards is no surprise-too frangible (and maybe too much velocity loss).

I'm not quite sure,Clive,what a 'sharper thump' means,but a bullet passing down the bore won't ''obturate" better with a bit more velocity,and I doubt that the inaccurate BLC2 powered 22/250 bullets were slower than my 222 ones.How zippy were your N120 successes?

The ultra light (VG) class just seem finicky-and rifle variable? Their low BC also just can't maintain any advantage over even modest distance,compared to better BC/construction bullets.They are best seen as very 'niche' use bullets.

 

Price becomes very moot,if they are not fit for purpose-but fine 200y tin can plinkers -what isn't? :-)
