    Tite Group temp. sensitive?

    in 10mm/40 Caliber

    Posted

    I'm going to Florida next week for the Open and was a curious how much of a change I'd see over the chrono. Seeing as there is still 2 feet of snow at the range here I did a test today. I loaded my match load of titegroup and 180Fmj's with an OAL of 1.14, and went out to the range. When I got there I loaded 2 mags and put them in a plastic bag and stuck them in the snow. I loaded 2 more mags and stuck them in my pants pocket. I also took the gun out and put it on the table to cool off right away before setting up the chrono and stuff.

    With everything cold and outside air temp of +5C the first string on 19 rounds gave:

    AVG Vel 968.7

    SD 11.13

    AVG ME 375.18

    AVG PF 174.37

    HI Vel 987

    LO Vel 951

    Max Dev 36

    Then I had some practice time to get everything (including myself) warmed up. The second string of 17 rounds with everything warm gave:

    AVG Vel 957.0

    SD 9.78

    AVG ME 366.19

    AVG PF 172.27

    HI Vel 974

    LO Vel 942

    Max Dev 32

    So I'm happy with that for the Florida match, but may just bump the load .1 for summertime matches up here where major is 170pf.

    STI Trojan vs Kimber Match Stainless II

    in 1911-style Pistols

    Posted

    For those of you guys with the Trojan, what is your impression of the front strap stippling?

    Thx

    The front strap works good, I actually took a little off it with sandpaper. I started in IPSC with a trojan, I knew I wanted a .45, read lots, asked lots of questions, just like you are doing. Most of the guys told me I would probably end up having more than one gun from STI so why not get started with them.

    I'm on STI # 2 and very happy with both.

    Dry Fire Tip

    in Tips for Improvement

    Posted

    Great thread,

    I keep my dummy (no primer,no powder) rounds in a plastic bag on my desk with my dryfire timer, steve anderson book, and spreadsheet for times. I keep the mag loaded for dryfire drills and for reloads I use 2 mags. The one coming out of the belt is full and the one dropping out of the gun has one left in it (so that it's light).

    +1 for Dillon one more time

    in Dillon Precision Reloading Equipment

    When I bought all my reloading stuff a couple years ago, a bought a bullet puller along with everything else. At some point the plastic nut that holds the round in the hammer was broken. I really didn't want to order another bullet puller and didn't see the nut on the site. So I called to see if I could buy one, they said "no you can't, what's your address?" A week later there's a package in the mail from Dillon with the replacement nut.

    Thanks guys.

    failure to ignite wsr primer

    in Miscellaneous BEginners

    Posted

    Could one of you guys that has both the rifle and pistol primers measure them for depth? I was told that rifle primers are longer in depth, and therefore harder to get seated below flush. Just curious :) My .40 std gun never hiccuped until I tried rifle primers, then I was getting a fail to fire every couple hundred rounds.

    "Custom" work on a gun you don't expect

    in General Gunsmithing

    Sorry to hear about your frustration. The F/O front sight on my gun broke halfway throught he season this year, I measured it, and searched the net for the same sight. None, so I went to my gunsmith with a drawing on a piece of paper of the dimensions I wanted, and a slight change so it hopefully wouldn't break. 1 hour later it was done!

    Differances between Titegroup & Longshot

    in 10mm/40 Caliber

    Posted

    I have been shooting titegroup for 3 years, and a few friends suggested trying longshot, so I picked up 2 lbs (winter being the time to experiment). Talking with various people that are a lot of things about longshot that I like. 175 PF loads w/ titegroup in my gun is right at max, and the pressure is way up there, longshot is right at the bottom of the scale. Longshot also fills the case more, one less chance of a double charge when the bullet won't seat...

    I've run some loads over the chrono and was kinda surprised by the results.

    Here is my match load in titegroup:

    AVG Vel 968.9

    SD 9.69

    AVG ME 375.31

    AVG PF 174.40

    HI Vel 988

    LO Vel 955

    Max Dev 33

    Here was my starting load with longshot:

    AVG Vel 1004.8

    SD 21.01

    AVG ME 403.63

    AVG PF 180.86

    HI Vel 1029

    LO Vel 957

    Max Dev 72

    Second load of longshot .1 less:

    AVG Vel 972.4

    SD 24.07

    AVG ME 378.02

    AVG PF 175.03

    HI Vel 1007

    LO Vel 934

    Max Dev 73

    Look at the differance in SD and MD, it's double. I've looked at a bunch of my titegroup loads and they are all about the same.

    I'm leaning towards sticking with titegroup, but still have more longshot to shoot.

    Any thoughts?

    SVI slidestop in an STI

    in General Gunsmithing

    Posted

    I picked up an SVI slidestop for my Edge, after being very pleased with the ambi safety from SVI. The slidestop doesn't appear to be long enough, in that the springloaded retaining pin doesn't put any tention on the slidestop and it will fall back out. Anybody else seen this?
