I am in possession of a reasonable ammount of H4895, and a number of 110gr round nose soft point bullet heads (four different types). I had been hoping to make up a "gentle" round for my Sako 75 in 30-06, for target, plinking, and occasional vermin use. I started off with 48gr of H4895 to give 2800fps, with a COAL of 2.915". The best group I could achieve was just under two and a half inches at 100 yards. Thinking that the problem may be in the velocity I worked my way up to 56gr. The result was the same. I also tried 55.5gr of CFE223, without improvement. If I did a group of five shots I was able to get two bullets close together, but the others were like a shotgun spread. When I fired 125gr Nosler's, 0.873", so it is not me or the gun. The heads are Speer 1845, Sierra 2100, Speer 1846 and some made by Norma. Am I right in now thinking they are for slower speeds in a Carbine, or my twist rate is not fast enough ?

Strange. I've used quite a few of those types in my 30-30 rifles to good effect.
I don't know what to suggest other than maybe a faster powder for a slower load to plink with or small game.
If you want to dispose of them I do a recycling service for unwanted bullets. It's totally free, except for the postage of course.

You are mixing terminolgy up a fair bit in your post.
Bullets are bullets, heads are at the opposite end of a cartrige from a bullet.
Does your Sako 75 in 30-06 have a 1:11" twist ?
Did I read right that the 125gr Nosler bullets grouped ok ?
If you measure the length of the bullets you have from Speer. Sierra and Norma and plug this into Don Millers formula what does it tell you ?
Are the stability figures coming out below 1.4 ?
Are the Speers and Sierras longer than the Noslers ?
This will give you a good indication of the length-v-stability

I've used the 110's in a few rifles , including an M1 Carbine . I've never achieved outstanding accuracy in any of my bolt rifles with them If I pushed the velocity . My loads shot better than what you're getting , about 1 1/2 inches , but that was about it . I eventually went with " The Load " ( 13 grs of Red Dot ) in various 308s , 30/30s and 30/06s . They shot really well inside of 50 yards or so and accounted for a lot of Snowshoe Hares and Grouse ( legal here ) over the years . Not exactly what you're looking for , but it is an option .

I have a Weatherby in 300win, 1 in 10 twist.
Before I purchased a 243, I tried to calm the 300 down a bit for Roe. I used Hornady 110g vmax #23010 with N140 66g to get sub 1" at 100ydrs.
The Speer 110g #1855 bullet didn't do as well.
Given N140 is in a similar position on the fast/slow burn rate scale as H4895, you might be a little low on powder.
However, my guess is that the COAL of the loaded round, with 110g bullets, is TOO short for your rifle and the jump to the lands is the issue.

I used to use the Sierra 110 RNSP in my Blackout. They were superb thumpers at short range but if I tried to push them too hard accuracy went to pot. 20.5gn of powder was very good, 21 was awful. I'd imagine you'll get to that point pretty quickly in a bigger cased 30cal.
try using the h4895 with a 60%reduced load <reduced from maximum charge?> dont reduce by more but slowly increase the charge until you get the grouping you require. my 308 shoots the 110gr under an inch with 31.8 grs BUT that from a 1 in 10 twist 20" barrel 308 win .h4895 is an excellent powder for reduced loads . send hodgdon an e-mail or look on line for hodgdon reduce load data. good luck.

i never had a lot of luck with those bullets , i think they are really designed for smaller cases with possibly less jump to rifling? also it's unlikely your rifling twist isn't fast enough more likely it's too fast for such a short bullet ?
also , for me you can call the components whatever you like and if i am not sure i'll just ask you.........

The 110gr RN bullets are designed for the M1 Carbine which has a 1:20" twist.
TBH, I wouldn't expect any better grouping than what you're getting.
.30 CALIBER/7.62MM 110 GR. RN - Sierra Bullets
These rifle bullets were designed specifically for proper feeding in the 30 M1 Carbine. The 110 grain Roundnose #2100 is a soft point expanding bullet that expands reliably at carbine velocities. This bullet can be used in all 30 caliber cartridges (at reduced velocities) for small game. In...
