All of the Improved versions of the 219 Zipper pretty much gave 200 to 350 fps more than the standard Zipper. But the standard is no slouch in the velocity department. When I tell people I can easily reach 3500 fps with a 45 grain bullet, 3450 fps with a 50 grain bullet and 3300 fps with a 55 grain bullet, some look at me strangely. 9 21 ZIPPER - Hornady Manufacturing, Inc.Zipper was and is a respectable performer. Top velocities possible for the cartridge are only 100 fps lower than those which can be developed in the 224 Weatherby Varmintmaster. The Hornady 53 grain V-MAX or the 55 grain Spire Point are ne choices for the 219 Zipper and the cartridge is large enough to propel the wind-bucking 60 grain SP
A 709 Gr.50W Weathering Steel Description ASTM A709 Grade 50W equal grade are EN10155 :S355K2G1W,NFA 35-502E 36 WB 4.A709 Grade 50W is the specification used for steel plate used in the manufacture of bridges. A 709 Gr50W Weathering Steel Delivery Conditions ASSRA Forum - 219 Zipper loadsOne load for this was 32 gr of 4320 behind 40 gr. bullet, with groups at 100 yards said to have ranged from .350 to .750 inch. One load Ackley used for his Improved version was 37 gr. 4320 with 50 gr. bullet. Clarence Hill of Dixon, Illinois had an Improved Zipper design but I ASTM A709 - SSABASTM A709. The ASTM A709 is the Standard Specification for Structural Steel for Bridges and encompasses carbon, high-strength low-alloy, and quenched and tempered alloy steels used as structural plates in the construction of bridges. SSAB offers the following five grades of A709; 36, 50, 50W, HPS 50W and HPS 70W.
ASTM A709 Grade 50W I Beam also maintains excellent corrosion resistance, allowing it to maintain long lifespanseven during the most harsh atmospheric conditions. These properties make ASTM A709 Grade 50W I Beam ideal for applications such as bridges, and is a standard material employed by the American Association of State Highway and ASTM A709 GR.50W steel plateAccording to the different main chemical elements contains, A709 Grade 50W was divided as A709Gr50w type A, A709Gr50w type B, A709Gr50w type C.These three steel grades are equivalent to specification ASTM A 588/A 588M A588 Grade A,A588 Grade B and A588 Grade C.Low alloy steel plate A709 Grade 50W also owned the same minimum limited yield ASTM A709 Grade HPS 50W steel plateASTM A 709/A 709M A709 Grade HPS 50W is a kind of weathering steel plate with Cr,Ni,Mo alloy when rolling. The low alloy steel plate A709 GR HPS 50W shall have an atmospheric corrosion resistance index of 6.0 or higher calculated from the heat analysis in according to steel guide G 101-predictive method based on the date of larabee and Coburn.When properly exposed to the atmosphere,these

ASTM A709 VS ASTM A572 steel plate in - Bebon ChinaASTM A709 steel encompasses carbon, low alloy high strength, and quenched and tempered alloy steels. And ASTM A709 steel plate is utilized primarily in the manufacture of bridges. ASTM A709 steel consists of A709 grade 36, A709 grade 50 and A709 grade 50W , etc. ASTM A709 steel grades are often specified with Charpy tests referring the specific Corrosion Resistance of A709 Grade 50CR Steel ASTM A709 Grade 50CR, also specified as ASTM A1010, is a utility-grade stainless steel which performs well in corrosive environments. To date, six bridges have been constructed in five different states across the United States, with more bridges planned.
