2005年12月18日 · Your H4895 is 94 on the burn chart, IMR4895 is 96 on the burn chart. I've got one pound of the IMR I was going to use. But until I've got more of it I don't want to do load development on 1lbs of powder (308). I think you would be fine to develop loads with the IMR. Maybe some one with QL can chim in with some numbers.

2012年6月14日 · H4895 is a great powder for a .308. I would rate Varget, H4895 and IMR 4064 as my top three choices. The H part of H4895 indicates that it is a extreme line series powder made by Hogdon. This means it is temp stable, a common complaint of RE15 powder. Work up a load, I have found good velocity with a accuracy.

2020年3月24日 · Tried the H4895 out today with 168 SMK's and my gun definitely likes it better than varget and 4064. It's a little faster than those 2 powders also. With a charge of 41.6 and 42 GRS of H4895 put me at 2670FPS with SD's in the single digits and dam near shot one hole groups. Tested with Lab Radar.

2015年6月21日 · The powder used, IMR 4895, CCI BR2 primer, Starline brass, 465gr Wide Flat Nose cast of 50/50 Wheel Weights/lead - water quenched and sized .460, 5 shot groups.. 42gr - 1462fps - 2 3/4"group 43gr - 1528fps - 1 3/4" group - 5 into 3/4"

2013年5月18日 · Looking at the Hodgdon website it says 20.0gr -22.6gr max for H4895 powder for 77 SMK. However I also have a Sierra "manual" specific for AR15 reloading (.pdf I downloaded) that calls out loads of H4895 of 22.2gr - 23.6gr max for the 77 SMK. It is not as great a difference for the Varget (Hodgdon says 21.0 gr-23.7 gr and Sierra says 22.6 gr-23. ...

2010年12月13日 · Re: What Alliant powder is close to H4895 RL15 works fine in the M1A. Its burn rate is similar to IMR 4064, which had been a go to powder for the heavier bullets (ie 180-190s) in the M1 and M1A for many decades when those guns were used in HP shooting. My M1A NM shoots the 168/175s better with RL15 than with 4895.

2010年10月2日 · H4895 is a very good powder in the .308W with 150, 155 and 175 gr bullets. It is also an "Extreme" powder and is less sensitive to ambiant heat changes. I use the following loads in my M70 target rifle with a 26" barrel of 12" twist.

2011年3月6日 · Re: Powder! IMR4064 or H4895? I just performed my first reloading for 30-06 on an S1050. I used one pounders of IMR 4895, IMR 4064 and Varget. Not sure what your using for a powder measure but it was my experience that IMR 4895 flowed the best through the modifed (polished)Dillon measure = +/- .1 grns.

2012年4月11日 · I'm playing with 165g Nosler BTs and H4895 powder out of a 308 Winchester (Remington SPS-T) whose barrel has been cut to 18". It's going to be my hunting load. I started out testing near maximum loads (43.5g) per Hodgdon's site. Today I completed my third test, and have quite literally blown right past their recommended charge weights.

2010年4月18日 · The newer IMR powders are less temp sensitive and have copper eraser additive in the powder. (extreme powder plus copper erasing) H4895 = 0.23 fps change for each degree of temp change. IMR-4895 = 1.10 fps change for each degree of temp change. RL15 = 1.52 fps change for each degree of temp change. (Caliber 7.62mm, NATO, Ball, Special, …
