147 MG vs Precision with VV N320

[srrch]

I went to the range today to test out some new loads. I basically loaded the for two different bullet types MG's and Precisions. I thought that I'd post the data.

Common characteristics for both bullet types

Firearm: Smith & Wesson M&P Pro 9mm, Stock barrel.

Primer: Winchester small pistol standard

Cases: mixed

Caliber 9mm

Powder: 3.5 gr VV N320.

C.O.L; 1.110 to 1.115

Montanna Gold Bullets 147gr CMJ

12 shot string

High 898

Low 858

Extreme spread 40

Average 875

Standard deviation 12

Power Factor with stated weight of 147 gr = 128.6

Power Factor with actual average weight of 147.1 = 128.7

I excluded a low velocity round that registered 825 fps on my chrono

Precision Bullet Polymer Coated

10 shot string

High 963

Low 944

Extreme spread 19

Average 954

Standard Deviation 6

Power Factor with actual weight of 148.2 gr = 141.3

Power Factor with stated weight of 147 gr = 140.2

Welcome to the forum.

Temperature, where are you located?

Good info shows the extreme spread between the bullet that takes the most powder to make PF MTG, and the least.

Was there a noticeable feel between the two?

Next some accuracy testing.

How much smoke did you get off the Precision's with 320?

I want to try some Solo with the Precision 147.

There was definitely more felt recoil with the precision bullet. I was suprised about the difference in velocity. I didn't know it would be that significant. The temperature at the time of testing was between 65 and 70 degrees

A long while back I did some 9mm testing to compare the Precisions with various jacketed and plated bullets and had basically the same results - higher velocity with the Precisions, all other factors equal. If i can dig the data back up, i'll post it here.

For a long while now Precisions are what I shoot almost exclusively and am very pleased with them. I just finished a single stack 9mm sans a fully ramped barrel for my son that won't feed the Precision flat points, but that's hardly the bullet's fault. I was pretty disappointed, I now have to stock something round nosed for that that gun.

I want to try some Solo with the Precision 147.

I'm using Solo 1000 with precisions in 9mm, .40 and .45 without an objectionable amount of smoke. I tried VV320 with the Precisions a while back and didn't really notice much difference in the amount of smoke between it and Solo 1000. Now, TiteGroup, don't go there, it's awful.

Did some accuracy tests at the range tonight. At 25 yards benched, I got 3.5 inch group from the MG's and a 4.5 inch group from the Precisions. I'm not impressed with the accuracy at all. I've been reading about this on other posts. I may be in the market for a fitted after market barrel.
