6.5 PRC 153.5 grn Berger for 1000yds and 1 mile. - Long Range …
2023年11月13日 · At sea level, JBM ballistics does suggest you'll be pretty close to the super/sub sonic transition at 1760 yards, which could have some unwanted effects, though it appears you'll still be above mach 1 unless your shooting on a cold day. Just for perspective, a 1 mph wind is good for 20" of drift at a mile...better get those wind calls right on...
Harmonics and temperature? | Long Range Hunting Forum
2015年2月24日 · 2,766. Jan 2, 2020. #2. The metal properties in barrels don't significantly enough to change its resonant vibration low frequency and the several harmonic higher frequencies across most temperatures they're shot in. The zeros will change a lot more with altitude and powder temperature changes. Get zeros for each.
Winchester 21 Sharp - Long Range Hunting Forum
2024年10月3日 · AP2020 said: So my take, if Federal/Remington get on board through licensing, then it has a chance. Winchester does not have the best track record in terms of supplying ammo [look at 17WSM and 400 Legend]. Supposedly, the non-heeled bullet of the 21 Sharp is cheaper to produce than the heeled 22LR bullet.
Stock fit - Long Range Hunting Forum
2024年10月11日 · Location. South Carolina. Oct 10, 2024. #1. I have a Winchester Model 70 338 WM. It's stainless, CRF, and Boss. It has a Jewell trigger added by the previous owner. I hated the plastic stock so I bought an HS Precision with an aluminum bedding block. The trigger would not fit so I used a Dremel to remove some aluminum.
Barrel/caliber change on 69 30-06 Winchester model 70
2024年4月2日 · For .28 caliber, my recommendation is .280 AI 26" or longer barrel with the right twist for the bullet you are going to use. If you venture to a wildcat, I would take advantage of the 6.5 RPM case capacity or as-is. Peterson will be the brass soon. .25 caliber: .25-06AI. .26 caliber: 6.5 RPM. .27 caliber: 270 AI.
Shilen barrel rifling-4 groove ratchet vs traditional
ND. May 3, 2014. #2. According to Mr. Bryan Litz in his book "Applied Ballistics for Long-Range Shooting", the smoother and shallower the engraving of the rifling is, the greater gyroscopic stability will be at extended long range. It doesnt make a huge difference but the difference between a 10% +- roll dampening coefficient results in a 4% ...
Muzzle brake for 300 Weatherby Mark V - Long Range Hunting …
2023年7月30日 · Mar 28, 2024. #7. A/1-61 said: I am having trouble deciding what the correct move is for a muzzle brake for my 300 Weatherby Magnum, Mark V, bought circa 1980. To start with, the outside diameter of the barrel at the tip is .610. I believe this means that I need to find something with a 1/2 by 28 thread.
22 Creedmore loads with 75 Bergers and ELD-m 75?
2016年1月17日 · Apr 7, 2019. #5. Built mine in a 22" so I could run a can. With 41.5 GR VV 550 at 8000ft elevation I get 3525. Only problem is the powder is way to temperature unstable. Because rifle is my out of big game season truck gun it gets used in temps from 25 below to 100 above zero! VV550 in this case is just too unstable!
7mm-08 pistol for elk hunting? - Long Range Hunting Forum
2009年10月9日 · 10,718. Location. Texas. Nov 16, 2020. #10. I hunt with a 7/08 Pistol and have been successful at distances of 500+yards on white tail using a 150 grain Ballistic tip bullet for the weight and ability to expand at lower velocities. For rifle hunting, I prefer the 120 bullets for the velocity (3000 to 3150 ft/sec).
Carbon Fiber Barrel with a Suppressor - Long Range Hunting Forum
2017年1月20日 · I think that setup might be the cat's *** for a deer rifle. There is no pressure issue inherent to using a carbon barrel and a suppressor versus a steel barrel. Suppressors do create more back pressure due to the powder burning through the suppressor baffles. This is what also helps to create more FPS from the same load while using a suppressor ...
