If it is on the shelf and works well there is a good chance I will buy it.
I try real hard to keep things simple and not have a huge variety of powders on hand. Hodgdon has many IMR4955 loads and surprisingly had some for the 6.5-06, a wildcat round.
Upon looking at the available data for IMR4955 on Hodgdon's site I compared IMR4955 with H4350 and H1000 that are 2 of my go to powders in the .280 (162 grain), 6.5-06(100, 120 & 140 grain) and .243 (87 VMax, 105 Amax). General performance in all three appeared to good and sort of similar despite the big differences in burn rates between H4350 and H1000. Hodgdon does not have any 87 grain data for the .243 so I looked at the 90 grain data.
Of note is the 6.5-06 with 100 grain bullets, a sort of spectacular up to 400 yard round. IMR4955 velocities were slightly more than those of H4350 but pressures shown were identical but powder charges were some 9 percent more using IMR4955. For heavier bullets I will probably stay with H1000, provided I can buy it. The 6.5-06 does well with bulky low density powders and a 57 grain charge of IMR4955 is not compressed and appears to fill the case to near 100 percent capacity.
IMR4955 appears to be real good in the .280 with 162 grain bullets. It is roughly comparable in velocity with H4350 with lighter bullets and H1000 with 105's in the .243.
Having the Hodgdon data on an Excel spread sheet would make it easier to play around with it.
