Fozzy357

Give VV340 a shot. I used 340 (3,6 grain)with my 147grain beveld base cast bullets, in my Pardini GT-9. Now all is good..

I fire a 143 grain slug with 3,5 grain N340 powder load. With a very light Dillon crimp.. This is THE only round I will compete with! But that is just me.

I am running 147 grain copper plated bullet over 3,5 grains of N340 in my Pardini GT9-6 at 915 fps. Never had any sign of tumbling.

I had a hard time getting the precision I needed in my Pardini GT9-6 until I loaded a .357 143 grain copper plated bullet over 3,5 grains of VV 340. Average velocity is 918fps. Now all is well

Yes, as you demonstrated with your Pardini. If you stay within reasonable pressures, no. I've shot .358 LEAD bullets from my Beretta 92 with no problems. I wouldn't try it with jacketed bullets. My standard size for lead bullets in 9x19 is .357. It makes a difference both in accuracy and in decreased leading. I stay with .355 or .356 with jacketed bullets. To slug your barrel: Get an oversize soft lead bullet and force it through the barrel. If you have a squib rod, that's the perfect rod to use to force the oversize bullet through the barrel, pounding it through with a rawhide or plastic hammer. When the bullet comes out, measure the groove diameter - the largest distance across the bullet. You should use lead bullets that diameter, or .001" larger. Thanks for taking the time to share this good information and advice

Not really sure how one slugs a barrel. Please tell me!

I have been trying a lot of reloading combinations for my 9mm, Pardini GT9-6 with a polygon barrel. So after another day of head scratching at the range, I see that my buddy has some new slugs for his 357 magnum. To make a long story short = I put a .357 RN copper plated bullet on top of 5,0 grains of VV340 and all of a sudden I was getting 40-50mm groups at 25 meters! Now here comes the questions: 1: Can larger diameter bullets cause better grouping? 2: Can this damage my barrel? You all must have known this one was coming 3: Can I try a .358 bullet or is this the bonehead move of the century?

A couple of table spoons of lamp oil does the trick for me!

I use 4,7 grains og N340 behind a selfcast 124 grain RN in my 6" Pardini. Average speed is 1130 fps. This load works wonders in my gun, but just dont do as I did the first time: I over crimmped and the bullit never touched the grooves. This resulted in a boat load of foul language, and 10" groupings

Kinetic energy (Ke) = 1/2 * M * V * V or, in the case of using weight instead of mass... Ke = m * v2 / (2 * 32.1739 * 7000) (where m is bullet weight in grains) See: http://en.wikipedia.org/wiki/Muzzle_enegry .45 230gr @ 725 FPS = 166.75 PF, but... 230 * 725 * 725 / (450,434.6) = 268.39 ft. pounds 9mm 115gr @ 1150 FPS = 132.25 PF, but... 115 * 1150 *1150 / (450,434.6) = 337.65 ft. pounds! That's about 25% more kinetic energy in your hand, but why does the 9mm (at minor PF) feel softer??? Well... Power Factor = M * V = momentum at muzzle (or shortly thereafter), but... Perceived recoil really has much more to do with impulse. Impulse is force applied over a specified time period. This explains it well...(impulse-momentum equation). So, to us shooters, the heavier bullet has more stationery "momentum" to overcome by exerting force, but also more time in the barrel (due to lower velocities) to achieve the desired terminal momentum (PF). So, this should explain now how two identical PF loads have different perceived recoil... .45 230gr @ 725 FPS = .40 185gr @ 901 FPS = 166.75 PF BUT (last one, I promise)... Since Force = M(ass) * A(cceleration) you have to create (901/725=) 24.28% more acceleration with only ((185/230)-1=) 19.56% less mass. Therefore, the force is greater with the .40 185gr projectile! Now, don't you feel smarter!? Ehh..I thought I was but now...........

My new Pardini GT-9 feels like it has a lots more "snap" or sharp recoil, the the .45 Pardini. Is it just me or, is there a good reason for this?
