That gun with a open style Red dot sight would work wonders in the swamps for hogs.
Nice gun!

I need a spicier large pistol primer

UPDATE: with a revelation
Now I don't know if starline made a run of large rifle primed 45win mag cases or if my particular batch of brass is just all on the extreme big end of the SAAMI pistol primer pocket depth spec. But anyhow the WLP primers I were using were getting seated a whopping .007" below flush (I shoulda checked this sooner)
After some careful measurement on test cartridges it turns out my primer pockets are running deep enough to seat a WLR primer .001" below flush, 20 cases measured before and after priming with no change in OAL confirm this. For me this is good news as I now have a hot enough primer with a tough enough cup to take this wildcat (actually 450BFG PTG) where I want to go.http://74.125.47.132/search?q=cache...bfg&cd=2&hl=en&ct=clnk&gl=us&client=firefox-a
I'm hoping that the overly deep .007" primer may be a contributing factor to the somewhat underwhelming accuracy I've thus far experienced, around 3moa for 5 @ 100 with WLP primed ww231 and the aforementioned WW296 loads.
More testing soon

krochus,
I've also found WLP primers aren't as "hot" as magnum specific primers from other companies even though they're marker for both standard and magnum use. When I want a LPM primer I use CCI LP Magnum primers. I feel they have the thickest cups and they are a true magnum primer.
If the brass you have will accept a LR primer that might be the way to go. Did you test the CCI LPM primers yet? (or did I miss that post?) If you did were the results better?
I doubt you will achieve acceptable results using a fast powder like W231. You might want to give H4227 a try since it's not nearly as hard to ignite as W296 although you won't get the same velocity. HS-6 will give you good velocities in the 45 Win Mag and it's an accurate powder too. (although I'm not sure of it's accuracy in the 45 Win Mag)

It wouldn't supprise one bit if they are made for LRP's, Starline have been know to cater for what reloaders seek, on occassion.
To me it seems that, with that light bullet weight, for the calibre. Theres gonna be some irradic ignition concerns when using slow ball powders, regardless of which primer ignites it.
Heavier bullets or a faster/easier to light powder may be options to explore, but since this is your project I only make the suggestion.

I haven't tried either of the new primers yet. But I'm about to hit the range within the hour.
Stay tuned!

well the results are in
shooting the previously mentioned load of up to 29grs of ww296 with 200grn xtp's now with a LR primer yeilded almost 200 fps more, virtually 100% propellant burn and ES numbers less than a quarter of those numbers with a WLP primer.
So yes primer does matter!
The problem is though that throughout all this testing my groups get no better than 3" at 100 for 5 shots, EVERY TIME. It's frustrating for sure, I guess I'll have to start over with a new scope and see if that helps.

I hope it's an optic or rifle issue for sure. Because at this point I don't have any more handloading rabbits to pull out of my hat.
