More hornet bullets.

I got that 3300fps with 12gn lil-gun in a Hornady K case & small rifle primer.

This one is 10%+ better than the book velocity.

That's 10% higher than the same combination but with 12.9 gr of lilgun out of same model rifle based on what I'm getting.

Now got two boxes of Sierra 40gn 1200's on the way to my RFD which I'm looking forward to testing, I think I'll abandon further testing the Hornady 45gn until I've had a play with them.

Let us know how you get on. Mine was better with the 45's than the 40's

Well I can already say that mine's as good with 40gn in .223" (Sierra 1100's) as I've managed with 45gn Hornady 2230, so the .224" (1200) should do even better.

But it did "one hole cloverleaf" my last 3 factory 45gn Remington rounds at 50yds.

[angrybear]

OK so I've got my Sierra 40gn SP's and just made up a selection of loads but I notice that on the vernier the coal is inconsistent

Closely comparing the finished rounds I can see the problem is with the bullets, the lead tips are inconsistent in shape & size, so that a more pointed tip is being seated a fraction deeper than the more rounded.

My Tester to set the die was spot on at 1.720", but the batch I've just done go from 1.731" down to 1.704" although the vast majority are 1.719-1.721"

I doubt that's going to help the grouping much

I guess it depends on if hey are all consistent to the ogive which they may well be, one thing I noted when loading soft points is if you squeeze the vernier too hard you squash the point and shorten the COL anyway!

Just thought you'd like to know, when I put your recipe into Quickload, it shows that your shooting way above the maximum safe load.

Wow - even more comfusion! It's a bit of a job when the bullet and powder manufacturers can't agree about load limits.
When working up loads by steps I always check for signs of over pressure and have never encountered any.

dickthomas - I'd be interested in seeing what Quickload says about Hornady V-Max in 35gr and 40gr with Lilgun.

[223AI]

I'd be interested what quick load would make of hornady brass, 45gr Speer soft point, fed 205 primer and 11.5gr IMR 4831

[Eligus]

Boydy it would probably tell you your insurance was invalid !

[223AI]

I know but I'm dying to try it, my sensible side screams nooooooo

[sackot]

Quickload says:
1) You'll barely fit it in.
2) It's too slow for hornet, half will burn after it exits the barrel.
Won't hurt you though (unless you stick a bullet) so no harm in trying.
Would need proposed OAL to give you precise predictions, it affects available case capacity.
