900_DRIVER Posted February 10, 2012 Share Posted February 10, 2012 What fps do most of you use to get the slide to function smoothly without any lag and with positive extraction? i have a completely stock G35 that i m loading 180 gr Berry's and VV320 (everybody's favorite here it seems) to about 3.8 Grs This combo is not doing any thing for reliable slide functioning, the chrono is averaging about 760-795 fps. My VV reloading manual mentions 4.1 as max, so i will bump it up. Just lookin for your 2 cents. thanks. Link to comment Share on other sites More sharing options...
SirLoin Posted February 10, 2012 Share Posted February 10, 2012 What's your OAL? What type of Berrys bullets are you using? Have you calibrated your reloader using, say, a digital scale or even a balanced scale? Link to comment Share on other sites More sharing options...
SirLoin Posted February 10, 2012 Share Posted February 10, 2012 More basic question: what do you mean by "not doing any thing for reliable slide functioning"? What exactly is happening? Link to comment Share on other sites More sharing options...
900_DRIVER Posted February 10, 2012 Author Share Posted February 10, 2012 (edited) I am using an RCBS 5-0-5 scale, (will be getting a digital in the future) Berry's 180 gr hollow point, set at 1.133~ This depth worked fine with Tite Group but i don't know what the FPS was with Tight Group because i didn't have a Chrono when i first started into reloading. I am using a Dillon 650 with Dillon dies. I thought maybe i should either seat them a little lower to build up a little pressure or just use more powder but I'm not sure which direction to go. to answer you question about the slide functioning - some times the slide will not eject the fired case or not feed the next bullet into the chamber or the spent brass barely clears the ejection port , sort of slow motion like, (the slide feels a little sluggish if that makes sense) Edited February 10, 2012 by 900_DRIVER Link to comment Share on other sites More sharing options...
SirLoin Posted February 10, 2012 Share Posted February 10, 2012 Okay. Your power factor is over the 135 PF base that most Glocks run well in, and your load specs look normal. What malfunctions are you experiencing? I'm guessing you might be getting stovepipe jams, from the stock recoil spring being too strong for your minor loads.

900_DRIVER Posted February 10, 2012 Author Share Posted February 10, 2012 i just edited the above to answer your question, I am an IDPA shooter and don't know the PF formula at this moment, sorry Link to comment Share on other sites More sharing options...
SirLoin Posted February 10, 2012 Share Posted February 10, 2012 No worries. Bullet grain * velocity (fps) / 1,000 = power factor. Basically, you need a lighter recoil spring, as the charge isn't strong enough cycle the slide fully to get rid of the spent brass. Get a 13 pound recoil spring to replace the stock recoil spring, and that should fix your problems. Link to comment Share on other sites More sharing options...
900_DRIVER Posted February 10, 2012 Author Share Posted February 10, 2012 i was thinking maybe the recoil spring was to strong since it is the Gen 4, and considered getting a lower weight spring also, i am just not sure which direction to go. i like the gun and the Gen 4 grip and bigger mag release so i am committed to making it work.

Whitefish Posted February 10, 2012 Share Posted February 10, 2012 I have a Gen 3 G35 that I run an aftermarket 15 lb Wolff recoil spring on a Jager steel guide rod. My major load is a 185 gr Precision Moly with 4.5 grains of N320 set at 1.135 OAL. I use a BarSto fitted barrel. Based on that, it would seem that your load is a little on the light side to reliably function one of the new Gen 4's with the dual spring recoil assembly. It might not even be enough to reliably function my Gen 3 with the 15 lb spring. Try a stouter load or a lighter recoil spring on one of the Jager steel guide rods built to replace the Gen 4 guide rod assembly. Link to comment Share on other sites More sharing options...
waktasz Posted February 10, 2012 Share Posted February 10, 2012 I shoot pretty much that exact load. I use a 13 pound ISMI spring with 2 coils cut off. Link to comment Share on other sites More sharing options...
SirLoin Posted February 10, 2012 Share Posted February 10, 2012 I'm assuming you're purposefully trying to load ammo that shoots soft / that attains a low power factor. The base PF in IDPA is 125, and your loads are hitting 137-143 PF (similar to mine), so you just need to change the recoil spring if you want to shoot loads these soft. If you don't want to change recoil springs and/or don't mind shooting stronger ammo, then load up to 4.1, and you won't have stovepipe jams anymore.

SirLoin Posted February 10, 2012 Share Posted February 10, 2012 I've been screwing around with 3.6 loads that get me to 130-135 PF, using 180 gr flat-point straight shoulder Berrys at 1.125 OAL. I was getting a stovepipe every 100 rounds or so, so I dropped to an 11 pound recoil spring, and that fixed the problem. I got the polymer guide rods and the 11 and 13 pound springs from Jager.

900_DRIVER Posted February 10, 2012 Author Share Posted February 10, 2012 yes i am trying to make a soft shooting load for the .40 so i can sort of fine tune the whole shooting system. Link to comment Share on other sites More sharing options...
900_DRIVER Posted February 10, 2012 Author Share Posted February 10, 2012 (edited) Are you guys generally happy with how the gun shoots with the lower lb springs? What weight is a stock Gen 4 spring? Edited February 10, 2012 by 900_DRIVER Link to comment Share on other sites More sharing options...
SirLoin Posted February 10, 2012 Share Posted February 10, 2012 I am. I'm a girlie old man, and my elbows/joints don't hurt as much after I shoot if I stick with soft loads. Link to comment Share on other sites More sharing options...
SirLoin Posted February 10, 2012 Share Posted February 10, 2012 17 pounds. Are you guys generally happy with how the gun shoots with the lower lb springs? What weight is a stock Gen 4 lb spring? Link to comment Share on other sites More sharing options...
waktasz Posted February 10, 2012 Share Posted February 10, 2012 Are you guys generally happy with how the gun shoots with the lower lb springs? What weight is a stock Gen 4 spring? Definitely yes. I like it better than 9mm. Link to comment Share on other sites More sharing options...
900_DRIVER Posted February 10, 2012 Author Share Posted February 10, 2012 it looks like a lower pound recoil spring is on the shopping list, thanks you guys Link to comment Share on other sites More sharing options...
noexcuses Posted February 10, 2012 Share Posted February 10, 2012 I would (and did) buy a 15# and a 13# springs when you buy them. At around $10 a piece its not real expensive to ge both to be able to experiment and see what youre gun likes. Link to comment Share on other sites More sharing options...
Paul-the new guy Posted February 11, 2012 Share Posted February 11, 2012 That gun should cycle fine with that load with all stock parts. I was shooting the exact same load in the exact same gun with an OAL of 1.135 and was getting 860fps I was getting 795fps out of a Glock 22 Link to comment Share on other sites More sharing options...
