rooster mcbee Posted August 14, 2020 Share Posted August 14, 2020 (edited) I need some opinion's for a light 9mm Steel Challenge load with Berry's 100 and 115 grain bullets out of a 5 inch barrel. Which would be better, Vihtavuori 310 or Vihtavuori 320? Also, would WST or WSF, or AA-2 be applicable with bullets this light? Thanks, Doug Edited August 14, 2020 by rooster mcbee Forget to put the caliber Link to comment Share on other sites More sharing options...
iflyskyhigh Posted August 14, 2020 Share Posted August 14, 2020 I did this with 95gr MG JHP out of a Gucci G34. I tried tried zip, PB, unique, TG, and HP-38 with terrible luck. Then I tried Bullseye and it was like a light switch. Finally settled on 3.6 grs 1083 FPS 17.1 SD / 49 ES (11lb Wolff recoil spring). It’s almost like cheating it’s so soft. No experience with the VN powders, but AANo 2 might be worth a shot. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
zzt Posted August 14, 2020 Share Posted August 14, 2020 Check to see that you can actually feed the 100s at the short OAL required. N310 no; way to temp sensitive. N320, WST, AA2; yes. If you want another recommendation, Alliant e3. Link to comment Share on other sites More sharing options...
iflyskyhigh Posted August 14, 2020 Share Posted August 14, 2020 I run the 95gr FMJ @ 1.020” in an agency arms barrel. No feeding issues. Not sure what gun you’re using. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
stick Posted August 15, 2020 Share Posted August 15, 2020 I toyed with the idea of making some 100gr Berry's with WST. Fail. I didn't like the load. I've heard that WSF works though, but I've never tried it. I simply kept shooting my 124gr loads with TG. Link to comment Share on other sites More sharing options...
Jmo2011 Posted August 15, 2020 Share Posted August 15, 2020 I’ve loaded quite a bit of Nobel sport Vectan BA-10 with both coated and fmj 115 bullets. Seems to work well down into the 90 power factor range if you tune the pistol for it. Link to comment Share on other sites More sharing options...
Sigarmsp226 Posted August 15, 2020 Share Posted August 15, 2020 I load W231 under a 124gr bullet at 3.5gr and it is a wonderful fully functional powder puff load and works 100% of the time in my P320X5 and my PCC rifle..... Link to comment Share on other sites More sharing options...
Dwbsig Posted August 15, 2020 Share Posted August 15, 2020 I’m using 3.7 grs of A#2 under a 95 gr coated lead bullet in my pcc, very soft load. Haven’t shot this load in any handguns yet. Link to comment Share on other sites More sharing options...
missed it by that much Posted August 15, 2020 Share Posted August 15, 2020 I've shot bayou 105 grain coated bullet with 3.5 grains titegroup. Plenty accurate and soft Sent from my SM-G960U using Tapatalk Link to comment Share on other sites More sharing options...
CZ85Combat Posted August 16, 2020 Share Posted August 16, 2020 I load N310 for my steel Challenge load. 115gn RN Blue Bullet, 3.4gn N310 @ 1.130 1009 fps very soft shooting. A 10# recoils spring is needed in my SP01 Shadow. Link to comment Share on other sites More sharing options...
tomv Posted August 17, 2020 Share Posted August 17, 2020 I use N310 exclusively for PCC SC loads. My current load is 2.4 gr N310 under 95 gr Montana Gold JHP seated at 1.085". 61 PF in my Taccom 5.5" barrel. The high impulse of this very fast powder provides positive cycling and ejection with minimal dot movement. I've read that N310 is temp sensitive but have not noticed a difference in the way my gun runs in temperatures from about 50 to 95 degrees.

jrdoran Posted August 17, 2020 Share Posted August 17, 2020 Steve, You had a ton of experience here. As Tom and I share the same load info for PCC and Open guns, can you be more specific as to what the side effects of cold weather will be on the N310 performance ? I certainly shoot SC 12 months / year and don't want to end up with reliability or worse squib issues come Dec-Mar. Link to comment Share on other sites More sharing options...
mvmojo Posted August 17, 2020 Share Posted August 17, 2020 I've been loading with WSF for years and years. But, I shoot heavier bullets. 3.4 gr WSF over 145 RN Bayou bullets loaded at 1.13 OAL gave me an avg PF of 121, nice and soft in an STI Steel Master running a 7 lb recoil spring. I think I could get the PF lower and still reliably cycle the gun but it feels good where it is. Link to comment Share on other sites More sharing options...
zzt Posted August 17, 2020 Share Posted August 17, 2020 (edited) Jim, my experience with N310 is with 45 ACP for bullseye. I set up the load in the 70 degree range and decided 3.8gr under a 200 LSWC gave me the accuracy I wanted. My 85 deg data was chrono'd at a different distance so it is not relevant. I can say the slide slammed back. The best I can estimate by correcting the chrono range is approximately 800 fps. At 72 it was 767 fps. At 56 it was 733. At 41 it was 705. At 32 deg it was so week the slide would not go back far enough to eject the case. Now, I have heard from several people that if you go to 4.5gr under a 200, a lot of this disappears and the SDs get much better. Supposedly VV says that is a safe load even though 4.0 is the max load listed in the VV manual. I moved on. I now use Alliant e3 for all of my pistol loads, except for the Open pistols. 3.0 under a 124 for PCC for SCSA. 3.0 under a 147 for outlaw steel that has to go down to score. 3.6 under a 105 coated (just because I had some) for one club that does not allow plated or jacketed, and steel must only ring to score. 2.8 under a 180 for 140 PF, and 3.6 under a 180 for 171 PF for Limited. 3.4 under a 200 LSWC (726 fps) in 45 for bullseye. There is zero temperature sensitivity. SDs are single digits for the 40 and 45 loads. In fact, the SD for my bullseye load is 4.97. That is astounding for a light load in a huge case. With N310 i was happy to keep SDs to double digits that started with one. As I mentioned, my experience with N310 is with 45. It is possible it works differently in 9mm.

CZ85Combat Posted August 18, 2020 Share Posted August 18, 2020 For the past 16 months I have used 5 lb of N310 in 9mm with 125gn blue bullets, shooting two times a week + some weekend matches. I have seen no temperature sensitivity. Link to comment Share on other sites More sharing options...
warpspeed Posted August 18, 2020 Share Posted August 18, 2020 I've been using Vectan BA-10 for SC loads for about 20 years now. It is in the same area as VV N310 as far as burn rate but uses less and is cheaper. 2.5 gr under a 115 gr or 100 gr or 95 gr but the gun is set up for SC so keep that in mind. It isn't an USPSA open gun that shoots major pf loads. Link to comment Share on other sites More sharing options...
Texaspaul Posted August 18, 2020 Share Posted August 18, 2020 100 Berry's and 105 Bayou and Summers with 3.8 grain of Sport Powder lite and accurate. Link to comment Share on other sites More sharing options...
RickT Posted August 22, 2020 Share Posted August 22, 2020 I'm using 3.6gr of N320 with 115gr Bayou. Haven't chrono'ed but it cycles my 9mm 1911 reliably. I've recently decided that I prefer 3.8gr, still very soft but the gun seems to stay on target better. I've also tried 4.0gr which I run in a PCC (8" barrel) and in the 1911 the recoil was still pretty minimal. My Sport Pistol loads are about 0.2 gr less.

mpmo Posted August 24, 2020 Share Posted August 24, 2020 Good stuff. Thanks for all the info here! Just started a load for SC. Using Berry’s RN 115 and N320. Looking forward to the days when I can pick and choose which bullets I load! But I will say, I am very happy with this combo in my cz tso. 105aprox PF. (Note, new shooter, new reloader.)

IATURNKEY Posted January 13, 2023 Share Posted January 13, 2023 (edited) I have been using 3.0 Tightgroup with 147 Hornady FMJ. The original intention was for a suppressor load, but it shoots well in most all my other “non-suppressed” guns. However, I don’t know if I would recommend it for steel challenge. I find a lighter bullet to be more functional in steel challenge. Edited January 13, 2023 by IATURNKEY Link to comment Share on other sites More sharing options...
Braxton1 Posted January 13, 2023 Share Posted January 13, 2023 Generally speaking, 147s at "soft Steel Challenge load" velocities are going so slow that you get NO feedback at all, especially on longer range stages like Speed Option and Outer Limits. You're already moving to the other box before the "lack of a clang" alerts you to an issue. 100 grain Berry's 9mm bullets at 1100 fps are great. Be sure to stay away from the 100 grain .380 bullets. The nose profile is so different from the 9mm version that you have to load them very short to have any neck tension exerted against the bullet.
