Anyone using N140 with Hornady 150gn SP interlock 303?

#1 Post by Rearlugs »

I've acquired some Hornady 303 150gn SP interlocks (to test the rumour that they are a bit fatter and have more bearing surface than PPU 174gn BT, and thus shoot better in some rifles).


I'm hoping to find an accurate load for target/competition shooting up to 600 yards (will take 1000 if that also works).


Vit themselves list a similar bullet - the Lapua 150gn Mega - and recommend a slightly faster powder N130 or N133. However, the only powder I have to hand in reasonable quantity is N140.



I just wanted ask if anyone has used N140 with these Hornadys and, if so, what sort of loads and results did you get?

Doh, I feel stupid!

You know what? I've got so used to using the Vit reloading data, which usually doesn't list any of the bullets available here in UK - that it never occurred to me to look at the Hornady reloading data for their own bullet.

Thanks!

Are you using them for .303 reloading or are you using them for 7.62x54r.....same diameter bullet.

Reason I ask is I have used the Hornady 150gr SP for reloading 54r with N140

I have found that just about every bullet listed as ".303/.311" are actually .310" in diameter, the one exception being the 170gr PPU FMJ which is actually .311"

More than a vested interest in 7.62x54r!

I'm using them for .303 reloading - in the hope that they are .311 or .312.

So far I have tried them with 38gn and 40gn N140, and tested them at 100 yds. Results are very good so far - they more or less halved the group size compared to the control rounds (PMP, HXP 76/83, PPU 174gn with 41.5gn N140). I think its probably the larger diameter thats fitting them better to the rifles (I was using four No4s to test).

Only problem is that they seem to shoot low, and I guess that gets much worse at range. I'd like to get them close to the ballistic performance of regular 303 7z, so that i can use similar sight adjustments for ranges out to 600 yds.

I think I'll either use Vit's recommendation of the faster N133, or use someone's load from another forum where they used 43gn N140 for the same type of 150 gn SP.

Interesting about the PPU 170gn - I'll try some of those as well.

Why dont you measure them then you will know for sure if they are .311 or .312.

All of Hornady data states that this bullet is .312 so I would be surprised if it isn't.

Do you know any one that has a copy of quick load if so ask them to run the numbers for you. I have ran the numbers you quoted out of curiosity. I wont put my findings on the forum but I am happy to pm you the results with the understanding that I can not guarantee you will get the same results in your firearm.

You need to reference the pressure tested data source for these loads as per the forum rules.
